REPORT OF RADIOLOGICAL SURVEY AT LOCATION MS00487

MONTICELLO, UTAH 84535
INTRODUCTION
The Surplus Facilities Management Program (SFMP) was established by the
Department of Energy (DOE) in 1978. SFMP is responsible for managing the
maintenance and surveillance of numerous DOE-ovned radioactively contaminated
facilities that have been declared surplus, and conducting a program leading
to the ultimate disposition of those facilities. The SFMP's fundamental
responsibility is to protect the public health and the environment from
potentially harmful radioactive contamination contained within or derived from
DOE-owned facilities. The Monticello mill site was declared surplus in 1981
and is currently awaiting remedial action to bring its condition up to present
decontamination and reclamation standards. Prior to performing remedial
action on the mill site, the properties surrounding the site and designated
privately owned properties in Monticello are being assessed. Oak Ridge
National Laboratory (ORNL) was directed by the DOE in July 1988 to assess the
radiological condition of privately owned properties in Monticello which have
been identified as possibly containing mill-related materials. If radiation
levels on these properties exceed EPA and DOE standards, the property is
eligible for clean-up under the Surplus Facilities Management Program. These
assessments are referred to as screening and scoping surveys. A detailed
investigation is referred to as a "screening" survey and an abbreviated form
as a "scoping" survey.
A radiological screening survey of location MS00487 was conducted on October
31, 1989 by Oak Ridge National Laboratory. This property consists of a vacant
lot containing one quonset hut. This survey was conducted using methods as
defined in the Vicinity Properties Management and Implementation Manual.
UMTRA-DOE/AL-050601 (March 1988) and the PAG UMTRA Project Procedures Manual
(April 1987), the Procedures Manual for the ORNL Radiological Survey
Activities (RASA) Program (April 1987) and the U.S. Department of Energy
Guidelines for Residual Radioactive Material at Formerly Utilized Sites
Remedial Action Program (FUSRAP) (Revision 2, March 1987). The radiological
survey of this property included: (1) a gamma scan of the entire ground
surface outdoors and indoors; (2) samples of outdoor soil; and (3) evaluation
of historical data when present. The gamma scan was conducted using a
Victoreen Portable Ratemeter, Model 490 which is a gamma scintillometer.
General location information is provided in Table 1, radiological survey
results are given in Tables 2 and 3, and supporting graphics are provided in
Figure 1. A view of the property is provided in Figure 2. All measurements
are gross readings; background has not been subtracted.
•
Location Number: MS00487
SIGNIFICANCE OF FINDINGS
A complete gamma screening survey was performed on this property. Background
gamma exposure rates ranged from 13-14 /iR/h outdoors and 12-14 pR/h indoors.
No regions of contamination were located on this property.
A reading of 17 pR/h was located east of the quonset hut. This reading was
from an old tarp that the owner stated was from the mine.
Status of adjacent properties is shown on Figure 1.

SIGNIFICANCE OF FINDINGS
A complete gamma radiation scan was done on this property. The general
background gamma exposure rates ranged from 12-15 pR/h indoors and 12-16 /jR/h
outdoors.
Two regions of elevated gamma exposure rates were found and labeled
Regions A and B (Figure 1). Radionuclide analysis of soil samples from
Region A yielded a net estimated area-weighted average 226Ra concentration of
3.1 pCi/g for surface soils and 5.1 pCi/g for subsurface soils. These values
do not exceed the DOE guidelines for surface and subsurface soils when
averaged over 100 m2.
Information pertaining to surrounding properties is located on Figure 1.

INTRODUCTION
The Surplus Facilities Management Program (SFMP) was established by the
Department of Energy (DOE) in 1978. SFMP is responsible for managing the
maintenance and surveillance of numerous DOE-owned radioactively contaminated
facilities that have been declared surplus, and conducting a program leading
to the ultimate disposition of those facilities. The SFMP's fundamental
responsibility is to protect the public health and the environment from
potentially harmful radioactive contamination contained within or derived from
DOE-owned facilities. The Monticello mill site was declared surplus in 1981
and is currently awaiting remedial action to bring its condition up to present
decontamination and reclamation standards. Prior to performing remedial
action on the mill site, the properties surrounding the site and designated
privately owned properties in Monticello are being assessed. Oak Ridge
National Laboratory (ORNL) was directed by the DOE in July 1988 to assess the
radiological condition of privately owned properties in Monticello which have
been identified as possibly containing mill-related materials. If radiation
levels on these properties exceed EPA and DOE standards, the property is
eligible for clean-up under the Surplus Facilities Management Program.
A radiological screening survey of location MS00254 was conducted on August 1,
1990 by Oak Ridge National Laboratory. This property consists of a single
family residence. This survey was conducted using methods as defined in the
Vicinity Properties Management and Implementation Manual. UMTRA-DOE/AL-050601
(March 1988) and the PAG UMTRA Project Procedures Manual (April 1987), the
Procedures Manual for the ORNL Radiological Survey Activities (RASA) Program
(April 1987) and the U.S. Department of Energy Guidelines for Residual
Radioactive Material at Formerly Utilized Sites Remedial Action Program
(FUSRAP) (Revision 2, March 1987). The radiological survey of this property
included: (1) a gamma scan of the entire ground surface outdoors and indoors;
(2) samples of outdoor soil; and (3) evaluation of historical data when
present. The gamma scan was conducted using a Victoreen Portable Ratemeter,
Model 490 which is a gamma scintillometer.
General location information is provided in Table 1, radiological survey
results are given in Tables 2 and 3, and supporting graphics are provided in
Figure 1. A view of the property is provided in Figure 2. All measurements
are gross readings; background has not been subtracted.
Location Number: MS00254
SIGNIFICANCE OF FINDINGS
A complete gamma screening survey was conducted at property location MS00254.
The survey found one region of elevated gamma exposure rates, labeled Region A
on Figure 1. Region A is located on the west edge of the property and is
likely due to spotty windblown contamination, as the property borders the
windblown line. A sample was collected at the location of the highest outdoor
gamma (HOG), and analyzed for Ra-226 concentration. The analysis revealed a
Ra-226 concentration of 3.6 pCi/g and 5.8 pCi/g for surface and subsurface
soils respectively. These values are below the DOE guidelines.
Background gamma exposure rates ranged from 13-15 uR/h indoors and 13-16
outdoors.

MONTICELLO, UT 84535
INTRODUCTION
The Surplus Facilities Management Program (SFMP) was established by the
Department of Energy (DOE) in 1978. SFMP is responsible for managing the
maintenance and surveillance of numerous DOE-owned radioactively contaminated
facilities that have been declared surplus, and conducting a program leading
to the ultimate disposition of those facilities. The SFMP's fundamental
responsibility is to protect the public health and the environment from
potentially harmful radioactive contamination contained within or derived from
DOE-owned facilities. The Monticello mill site was declared surplus in 1981
* and is currently awaiting remedial action to bring its condition up to present
decontamination and reclamation standards. Prior to performing remedial
action on the mill site, the properties surrounding the site and designated
privately owned properties in Monticello are being assessed. Oak Ridge
National Laboratory (ORNL) was directed by the DOE in July 1988 to assess the
radiological condition of privately owned properties in Monticello which have
been identified as possibly containing mill-related materials. If radiation
levels on these properties exceed EPA and DOE standards, the property is
eligible for clean-up under the Surplus Facilities Management Program.
A radiological screening survey of location MS00740 was conducted on July 18,
1990 by Oak Ridge National Laboratory. This property consists of a single
family residence with a commercial campground. This survey was conducted
using methods as defined in the Vicinity Properties Management and
Implementation Manual. UMTRA-DOE/AL-050601 (March 1988) and the PAG UMTRA
Prolect Procedures Manual (April 1987) , the Procedures Manual for the ORNL
Radiological Survey Activities CRASA^ Program (April 1987) and the U.S.
Department of Energy Guidelines for Residual Radioactive Material at Formerly
Utilized Sites Remedial Action Program (FUSRAP) (Revision 2, March 1987). The
radiological survey of this property included: (1) a gamma scan of the entire
ground surface outdoors and indoors; (2) samples of outdoor soil; and (3)
evaluation of historical data when present. The gamma scan was conducted
using a Victoreen Portable Ratemeter, Model 490 which is a gamma
scintillometer.
General location information is provided In Table 1, radiological survey
results are given in Tables 2 and 3, and supporting graphics are provided in
Figure 1. A view of the property is provided in Figure 2. All measurements
are gross readings; background has not been subtracted.
Location Number: MS00740
SIGNIFICANCE OF FINDINGS
A complete gamma radiation scan was done on this property. The general
background gamma exposure rates ranged from 12-14 fiR/h Indoors and 13-16 piR/h
outdoors.
No regions of elevated gamma exposure rates were detected anywhere on this
property.
One point source of petrified wood with a gamma exposure rate of 44 pR/h was
located east of the house (Figure 1).
Information pertaining to surrounding properties are located on Figure 1.

A radiological screening survey of location MS00309 was conducted on
May 17, 1990 by Oak Ridge National Laboratory. This property consists of a
residential single family. This survey was conducted using methods as defined
in the Vicinity Properties Management and Implementation Manual. UMTRA-DOE/AL-
050601 (March 1988) and the PAG UMTRA Project Procedures Manual (April 1987),
the Procedures Manual for the ORNL Radiological Survey Activities (RASA)
Program (April 1987) and the U.S. Department of Energy Guidelines for Residual
Radioactive Material at Formerly Utilized Sites Remedial Action Program
(FUSRAP) (Revision 2, March 1987). The radiological survey of this property
included: (1) a gamma scan of the entire ground surface outdoors and indoors;
(2) samples of outdoor soil; and (3) evaluation of historical data when
present. The gamma scan was conducted using a Victoreen Portable Ratemeter,
Model 490 which is a gamma scintillometer.
General location information is provided in Table 1, radiological survey
results are given in Tables 2 and 3, and supporting graphics are provided in
Figure 1. A view of the property is provided in Figure 2. All measurements
are gross readings; background has not been subtracted.
Location Number: MS00309
SIGNIFICANCE OF FINDINGS
A complete gamma radiation scan was done on this property. The general
background gamma exposure rates ranged from 11-13 pR/h indoors and 13-15 ^R/h
outdoors.
Two regions of elevated gamma exposure rates were detected and labeled
Regions A and B (Figure 1). Radionuclide analysis of soil samples from
Regions A and B did not exceed background levels averaged over 100 m2.
Region A spills over to 233 Abajo drive (MS00310) to the south.
Information pertaining to surrounding properties is located on Figure 1.

REPORT OF RADIOLOGICAL SURVEY AT LOCATION MS00252
NORTH 3RD EAST STREET A000O00FOO3A
MONTICELLO, UT 84535
INTRODUCTION
The Surplus Facilities Management Program (SFMP) was established by the
Department of Energy (DOE) in 1978. SFMP is responsible for managing the
maintenance and surveillance of numerous DOE-owned radioactively contaminated
facilities that have been declared surplus, and conducting a program leading
to the ultimate disposition of those facilities. The SFMP's fundamental
responsibility is to protect the public health and the environment from
potentially harmful radioactive contamination contained within or derived from
DOE-owned facilities. The Monticello mill site was declared surplus in 1981
and is currently awaiting remedial action to bring its condition up to present
decontamination and reclamation standards. Prior to performing remedial
action on the mill site, the properties surrounding the site and designated
privately owned properties in Monticello are being assessed. Oak Ridge
National Laboratory (ORNL) was directed by the DOE in July 1988 to assess the
radiological condition of privately owned properties in Monticello which have
been identified as possibly containing mill-related materials. If radiation
levels on these properties exceed EPA and DOE standards, the property is
eligible for clean-up under the Surplus Facilities Management Program.
A radiological screening survey of location MS00252 was conducted on August 2,
1990 by Oak Ridge National Laboratory. This property consists of a vacant
lot. This survey was conducted using methods as defined in the Vicinity
Properties Management and Implementation Manual. UMTRA-D0E/AL-050601 (March
1988) and the PAG UMTRA Project Procedures Manual (April 1987), the Procedures
Manual for the ORNL Radiological Survey Activities (RASA) Program (April 1987)
and the U.S. Department of Energy Guidelines for Residual Radioactive Material
at Formerly Utilized Sites Remedial Action Program (FUSRAP) (Revision 2, March
1987). The radiological survey of this property included: (1) a gamma scan of
the entire ground surface outdoors; (2) samples of outdoor soil; and (3)
evaluation of historical data when present. The gamma scan was conducted
using a Victbreen Portable Ratemeter, Model 490 which is a gamma
scintillometer.
General location information Is provided in Table 1, radiological survey
results are given in Tables 2 and 3, and supporting graphics are provided in
Figure 1. A view of the property is provided in Figure 2. All measurements
are gross readings; background has not been subtracted.
Location Number: MS00252
SIGNIFICANCE OF FINDINGS
A complete gamma radiation scan was done on this property. The general gamma
exposure rates ranged from 13-15 pR/h. There are no structures on this
property.
One region of elevated gamma exposure rates was located and labeled Region A
(Figure 1). Soil samples taken from Region A did not exceed background levels
when averaged over 100 m2 (Table 3).
Region A spills over to the south to MS00248 which is to be surveyed by
Geotech.

REPORT OF RADIOLOGICAL SURVEY AT LOCATION MS00754
197 NORTH 2ND WEST STREET
MONTICELLO, UT 84535
INTRODUCTION
The Surplus Facilities Management Program (SFMP) was established by the Department of
Energy (DOE) in 1978. SFMP is responsible for managing the maintenance and surveillance of
numerous DOE-owned radioactively contaminated facilities that have been declared surplus, and
conducting a program leading to the ultimate disposition of those facilities. The SFMP's
fundamental responsibility is to protect the public health and the environment from potentially
harmful radioactive contamination contained within or derived from DOE-owned facilities. The
Monticello mill site was declared surplus in 1981 and is currently awaiting remedial action to bring
its condition up to present decontamination and reclamation standards. Prior to performing
remedial action on the mill site, the properties surrounding the site and designated privately
owned properties in Monticello are being assessed. Oak Ridge National Laboratory (ORNL) was
directed by the DOE in July 1988 to assess the radiological, condition of privately owned
properties in Monticello which have been identified as possibly containing mill-related materials.
If radiation levels on these properties exceed EPA and DOE standards, the property is eligible for
clean-up under the Surplus Facilities Management Program.
A radiological screening survey of location MS00754 was conducted on August 22, 1990 by Oak
Ridge National Laboratory. This property consists of a school. This survey was conducted using
methods as defined in the Vicinity Properties Management and Implementation Manual.
UMTRA-DOE/AL-050601 (March 1988) and the PAG UMTRA Project Procedures Manual
(April 1987), the Procedures Manual for the ORNL Radiological Survey Activities fRASA)
Program (April 1987) and the U.S. Department of Energy Guidelines for Residual Radioactive
Material at Formerly Utilized Sites Remedial Action Program (FUSRAP) (Revision 2, March
1987). The radiological survey of this property included: (1) a gamma scan of the entire ground
surface outdoors and indoors; (2) samples of outdoor soil; and (3) evaluation of historical data
when present The gamma scan was conducted using a Victoreen Portable Ratemeter, Model 490
which is a gamma scintillometer.
General location information is provided in Table 1, radiological survey results are given in Tables
2 and 3, and supporting graphics are provided in Figure 1. A view of the property is provided in
Figure 2. All measurements are gross readings; background has not been subtracted.
SIGNIFICANCE OF FINDINGS
Location Number MS00754
A radiological survey at this site revealed the background exposure rates to be 12-14 uR/h
outdoors and 13-17 uR/h indoors.
Indoors, two point sources, a piece of petrified wood and an ore sample were found to have
readings of 150 uR/h and 300 uR/h, respectively. Both point sources were part of classroom rock
collections.
No other elevated gamma exposure rates were detected during the survey.
Location Number. MS00754
FINDINGS
SITE CONTAINS RADIATION LEVELS WHICH [ ] EXCEED [x] DO NOT EXCEED THE
DOE GUIDELINES BELOW:
Outdoor gamma is < background plus the acceptable difference or 20% averaged over 100 nr
^Ra is <5 pCi/g above background in surface 15 cm sou* layer averaged over 100 m2

Dear Mr. Jensen:
The U.S. Department of Energy (DOE), as authorized by the Atomic Energy Act as
Amended (1954), has been directed to conduct remedial action at Vicinity
Properties contaminated with residual radioactive material which resulted from
the Manhattan Engineer District/Atomic Energy Commission operations at the
Monticello Mill site owned by DOE.
The Vicinity Properties in Monticello are under the regulatory framework of
the comprehensive Environmental Response, Compensation, and Liability Act
(Superfund) as Amended (1986). The Monticello Vicinity Properties were
formally included on the National Priorities List on June 10, 1986. As a
result, cleanup activities at the Vicinity Properties are required and must
satisfy the requirements-of the Superfund program.
A preliminary surficial radiological survey of your property as identified
above has not revealed the presence of-residual radioactive material in excess
of standards established the Environmental Protection Agency (40 CFR 192).
Therefore, the DOE has determined that your property does not require remedial
action under Superfund program. You will be notified if further radiological
assessments on adjacent properties identify buried radioactive contamination
extending onto your property.
Your property does not exceed project guidelines with the exception of
collectible ore samples not derived from Monticello mill site operations.
If you wish to dispose of this material, please contact a DOE contractor
employee, and' they will assure this material is properly incorporated into
the final Monticello repository.
Should you have any questions regarding the Monticello Vicinity Properties
Superfund program, please write to me at the above address, or call me collect
at 303-248-6001. Your cooperation in granting access to your property to
conduct a radiological survey is greatly appreciated.
Sincerely,
Michael K. Tucker, Director

INTRODUCTION
The Surplus Facilities Management Program (SFMP) was established by the Department of
Energy (DOE) in 1978. SFMP is responsible for managing the maintenance and surveillance of
"numerous DOE-owned radioactively contaminated facilities that have been declared surplus, and
conducting a program leading to the ultimate disposition of those facilities. The SFMP's
fundamental responsibility is to protect the public health and the environment from potentially
harmful radioactive contamination contained within or derived from DOE-owned facilities. The
Monticello mill site was declared surplus in 1981 and is currently awaiting remedial action to bring
its.condition up to present decontamination and reclamation standards. Prior to performing
remedial action on the mill site, the properties surrounding the site and designated privately
owned properties in Monticello are being assessed. Oak Ridge National Laboratory (ORNL) was
directed by the DOE in July 1988 to assess the radiological condition of privately owned
properties in Monticello which have been identified as possibly containing mill-related materials.
If radiation levels on these properties exceed EPA and DOE standards, the property is eligible for
clean-up under the Surplus Facilities Management Program.
A radiological screening survey of location MS00774 was conducted on October 10, 1990 by Oak
Ridge National Laboratory. This property consists of vacant land. This survey was conducted
using methods as defined in the Vicinity Properties Management and Implementation Manual.
UMTRA-DOE/AL-050601 (March 1988) and the PAG UMTRA Project Procedures Manual
(April 1987), the Procedures Manual for the ORNL Radiological Survey Activities (RASA)
Program (April 1987) and the U.S. Department of Energy Guidelines for Residual Radioactive
Material at Formerly Utilized Sites Remedial Action Program (FUSRAP) (Revision 2, March
1987). The radiological survey of this property included: (1) a gamma scan of the entire ground
surface outdoors; (2) samples of outdoor soil; and (3) evaluation of historical data when present.
The gamma scan was conducted using a Victoreen Portable Ratemeter, Model 490 which is a
gamma scintillometer.
General location information is provided in Table 1, radiological survey results are given in Tables
2 and 3, and supporting graphics are provided in Figure L A view of the property is provided in
Figure 2. All measurements are gross readings; background has not been subtracted.
Location Number: MS00774
SIGNIFICANCE OF FINDINGS
A complete gamma radiation screening survey was conducted of this property. The property
consists of open pasture and plowed fields.
The outdoor background gamma exposure rates ranged from 13-15 uR/h. One region of spotty
16 uR/h exposure rates was detected and labeled Region A (Figure 1). Region A appears to be
windblown contamination with an exposure rate range of 15-17 uR/h. Soil samples from Region
A yielded a net estimated area-weighted average ^Ra concnetration of <1.0 pCi/g for surface
soils. This value is below the inclusion criteria of 5 pCi/g for surface soils averaged over 100 m2.
Location Number: MS00774

INTRODUCTION
The Surplus Facilities Management Program (SFMP) was established by the
Department of Energy (DOE) in 1978. SFMP is responsible for managing the
maintenance and surveillance of numerous DOE-owned radioactively contaminated
facilities that have been declared surplus, and conducting a program leading
to the ultimate disposition of those facilities. The SFMP's fundamental
responsibility is to protect the public health and the environment from
potentially harmful radioactive contamination contained within or derived from
DOE-owned facilities. The Monticello mill site was declared surplus in 1981
and is currently awaiting remedial action to bring its condition up to present
decontamination and reclamation standards. Prior to performing remedial
action on the mill site, the properties surrounding the site and designated
privately owned properties in Monticello are being assessed. Oak Ridge
National Laboratory (ORNL) was directed by the DOE in July 1988 to assess the
radiological condition of privately owned properties in Monticello which have
been identified as possibly containing mill-related materials. If radiation
levels on these properties exceed EPA and DOE standards, the property is
eligible for clean-up under the Surplus Facilities Management Program. These
assessments are referred to as screening and scoping surveys. A detailed
investigation is referred to as a "screening" survey and an abbreviated form
as a "scoping" survey.
A radiological screening survey of location MS00814 was conducted on
April 4, 1990 by Oak Ridge National Laboratory. This property consists of a
single family residence. This survey was conducted using methods as defined
in the Vicinity Properties Management and Implementation Manual. UMTRA-D0E/AL-
050601 (March 1988) and the £AG UMTRA Project Procedures Manual (April 1987),
the Procedures Manual for the ORNL Radiological Survey Activities (RASA)
Program (April 1987) and the U.S. Department of Energy Guidelines for Residual
Radioactive Material at Formerly Utilized Sites Remedial Action Program
(FUSRAP) (Revision 2, March 1987). The radiological survey of this property
included: (1) a gamma scan of the entire ground surface outdoors and indoors;
(2) samples of outdoor soil; and (3) evaluation of historical data when
present. The gamma scan was conducted using a Victoreen Portable Ratemeter,
Model 490 which is a gamma scintillometer.
General location information is provided in Table 1, radiological survey
results are given in Tables 2 and 3, and supporting graphics are provided In
Figure 1. A view of the property is provided in Figure 2. All measurements
are gross readings; background has not been subtracted.
Location Number: MS00814
SIGNIFICANCE OF FINDINGS
A complete gamma screening of this property revealed background gamma exposure
rate ranges of 13-14 />R/h outdoors and 12-14 /*R/h indoors.
One region of elevated gamma exposure rates was found outdoors, shown as
Region A In Figure 1. Soil samples taken from Region A yielded net estimated
area-weighted average 228Ra concentrations of <1 pCi/g for both surface and
subsurface soils (Table 3). These values are less than the DOE guidelines of
5 pCi/g for surface soil and 15 pCi/g for subsurface soil averaged over 100
ma.
Two petrified wood point sources were located in the west and south yard
(Figure 1).
No regions of elevated gamma exposure rates were detected indoors.
Information regarding surrounding properties is located on Figure 1.
