Thera is evidence that in [a other areas only two or With the infornation available in this report it would be possible to dstermine the amount of fission products that have fallen in a given area of Nevada and Utah from the NPC Test Operations within 2CO miles of the Test Site. A close study of Figure 10 shows that in the Ziko-Alamo fertile valley (population 1200) the following threa shots were superimposed: JU/K, innie, Harry and Simon, Cer- tainly the concentration of fission products in such areas is high enough to study the plant and animal uptake of radioisotopes in a practical basis, The Figures in this report indicate radioactive falle out using isodose lines in roentzgens. ‘The dosage indicated would be raceived when exposure time is considered infinite, a UNCLASSIFIED The relation between ies =.
