[en] Potential radiation-induced effects from inhalation and ingestion of land external exposure to radioactive materials at the Jackpile-Paguate uranium mine complex near Paguate, New Mexico, were analyzed. The Uranium Dispersion and Dosimetry (UDAD) computer code developed at Argonne National Laboratory was used to calculate the dose rates and the time-integrated doses to tissues at risk as a function of age and time for the population within 80 km of the mines. The ANL computer code Potential Radiation-Induced Biological Effects on Man (PRIM) then was used to calculate the potential radiation-induced somatic and genetic effects among the same population on the basis of absolute and relative risk models as a function of duration of exposure and age at time of exposure. The analyses were based on the recommendations in BEIR II and WASH-1400 and the lifetable method. The death rates were calculated for radiation exposure from the mines and for naturally induced effects for 19 age cohorts, 20 time intervals, and for each sex. The results indicated that under present conditions of the radiation environment at the mines, the number of potential fatal radiation-induced neoplasms that could occur among the regional population over the next 85 years would be 95 using the absolute risk model, and 243 using the relative risk model. Over the same period, there would be less than two radiation-induced genetic effects (dominant and multifactorials). After decommissioning f the mine site, these risks would decrease to less than 1 and less than 3 potential radiation-induced deaths under the relative and absolute risk models, respectively, and 0.001 genetic disorders. Because of various sources of error, the uncertainty in these predicted risks could be a factor of five
