Energy Fuels ALARA goal is to maintain exposures below 25 mrem/yr ECLs in this analysis are based on 50 mrem/yr except radon which uses 25 mrem/yr. Table 2 ECLs are based on 50 mrem/yr. ECLs for radon were calculated using distance and wind speed from assumed stack source to BHV stations. Calculated ECLs provide inclusion of ingrowth of daughters. Annual values reflect averaging dose rates for the four quarters, except for gamma, which is the sum of four quarterly values.
