REPORT OF RADIOLOGICAL SURVEY AT LOCATION MS00056
132 NORTH MAIN 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. These
assessments are referred to as screening and scoping surveys. A decailed
investigation is referred to as a "screening" survey and an abbreviated form
as a "scoping" survey.
A radiological (scoping or screening) survey of location MS00056 was conducted
on August 31, 1988 by Oak Ridge National Laboratory. This property consists
of a single family residence. This survey was conducted using methods as
defined in the Vlcinj?y Properties Management and Implementation Manual,
UMTRA-DOE/AL-050601 (March 1988) and the £A£ 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 Raterneter, 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: MS00056
SIGNIFICANCE OF FINDINGS
•Property location MS00056 consists of a vacant house and remnants of a garage.
The house and garage are dilapidated and were destroyed by fire several years
ago. A 1982 consent form gave access to the property for conducting
radiological surveys. There is currently no tenant.
A gamma survey found Regions A and B, shown on Figure 1. These regions are
from buried fragments of ore. There is no evidence that the ore is not
related to the Monticello mill site.
Samples SI-S3 were collected from Regions A and B and are tabulated in Table
3. Samples SI and S2 yield an average 224Ra concentration of 32 pCi/g. This
value meets the Hoc Spot Guideline for the areal extent of Region A (2.2 m2)
of 32 pCi/g.
Based on this finding, property location MS00056 is recommended for inclusion
in the SFMP.

Location Number: MS00025
SIGNIFICANCE OF FINDINGS
A consent to access was acquired from the owner, Mervin N. Sandberg, in 1982
by Bendix Field Engineering Corporation (BFEC). Historical data reveals that
the house was constructed in approximately 1956. Historical survey
information from a 1982 BFEC survey and a 1983 ORNL survey was reviewed. The
outdoor elevated gamma exposure rates (Table 2) recorded in the historical
ORNL survey were not detected during the recent site visit. It was never
detected by the BFEC survey.
The 1983 ORNL survey reports an ore sample which was collected and analyzed to
contain a 228Ra concentration of 630 pCi/g. The collection of this sample
apparently removed the contamination from the property, as it was not detected
during the August 25, 1988 site visit. In the same location, a piece of
pejtrified wood was detected and exhibits gamma of 17 pR/h. It is clearly not
related to the Monticello mill site.

REPORT OF RADIOLOGICAL SURVEY AT LOCATION MS00229
249 SOUTH MAIN 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. 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 MS00229 was conducted on August
16, 1989 by Oak Ridge National Laboratory. This property consists of a
commercial structure. This survey was conducted using methods as defined in
the Vicinity Properties, Management and Implementation Manual. UMTRA-DOE/AL-
050601 (March 1988) and the PA£ 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: MS00229
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 13-17 uR/h
outdoors.
No regions of elevated gamma exposure rates were found anywhere on the
property. One area with elevated gamma exposure rates of 18 uR/h was detected
in the bricks on the front of the building. It was determined that the
elevated readings were from naturally occurring radiation inherent in the
brick and not a direct result of mill operations.

• Location Number: MS00215
SIGNIFICANCE OF FINDINGS
A complete gamma radiation screening was performed on this property. The
general background gamma exposure rates ranged from 14-17 jjR/h outdoors and
13-15 jiR/h indoors.
One region of elevated gamma exposure rates was detected outdoors and labeled
Region A (Figure 1). Region A consists of windblown contamination.
Radionuclide analysis of soil samples (SI, S2, S3) yielded a net estimated
area-weighted average 22SRa concentration of 3.4 pCi/g. This value is below
the EPA criterion of 5 pCi/g for surface soils averaged over 100 m2.
Two point sources were detected (Figure 1) and identified as ore samples from
a mineral collection. The point sources had exposure rates of 600 pR/h and 25
MR/h.
This property spills over to adjacent properties (see Figure 1).

Properties Management and Implementation Manual. UMTRA-DOE/AL-050601 (March
1988) and the PAG/UMTRA Project Procedures Manual (April 1987). This property
contains radiation levels which do not exceed the DOE guidelines based on:
1) Outdoor gamma is less than background plus the acceptable difference or 20%
averaged over 100 m2, and 2) Indoor gamma is less than the acceptable difference
or 20% above background in all rooms.

Dear Mr. Wallo:
Radiation levels at the property identified below appear [] to [x] not to
exceed the guidelines specified by the U.S. Department of Energy for Residual
Radioactive Material at Formerly Utilized Sites Remedial Action Program
(FUSRAP) and Remote Surplus Facilities Management Program Sites (SFMP)
[Revision 2 March 1987].
This evaluation is based on [x] indoor and [x] outdoor screening measurement
criteria, [] indoor [] outdoor extended measurement criteria of the U.S.
Department of Energy Vicinity Properties Management and Implementation Manual
(UMTRA-DOE/A1-050601), Appendix A.
Other:
This property was an owner request due to concern because it is in close
proximity to a remediated property. Therefore, an "ad-hoc" survey was
performed to screen for elevated gamma. No samples were taken.
This finding is based upon the Inclusion Survey Contractor's assessment of the
[x] 22aRa concentration in the soil [] indoor radon daughter concentration
[xj indoor gamma exposure rate at this property.
Sincerely,
C\ A. Little, Ph. D.
