te ee, ee from the soil activity and depth profile measurements. Although the soil data indicate trace amounts of other gamma emitters, such as 1258p, 155Eu and 2hlarn, calculations of exposure rates based on the observed soil con- 4 centrations indicate that these nuclides contribute at most an additional the 3-5% to the exposure rate, and Mere therefore neglected. . Local anomalies, for example due to scrap,were also ignored under the assumption that they wil} - will be removed before resettlement and“probably contribute little more to eventual integrated total doses. Integral 5, 10, 30 and 70 year gamma-ray doses for each age group were calculated for each case shown in Table 1. These results were then combined the by folding intpresent population distribution (Table III). 4 “a ” Corrections were t . : . made for radioactive decay but no corrections were made for possible weathering and consequent deeper penetration of radionuclides into the soil. The results -of these calculations are given in Table IV and are labeled "unmodified", Additional calculations were made to ascertain the effect of carrying out eed ee 7 , . various reasonable attions to reduce exposure rates on the Atoll. ¥
