Dr. Bugher -k- May 13, 195k p33 Assume: inhalation and/or ingestion of 5 x 1093 fissions at p41, 193 intake is 1.2) x.1072 atoms the average eegn energy of 1193 is about 0.36 or 153 times that of T2031, yisl joy Thus, the ratio of doses = 0.7 13s Assume: inhalation and/or ingestion of 5 x 1073 tissions at D741, Y55 intake is 2.36 x 10% atoms. The average mean energy of 1135 45 abont 0.3 sev or 1.36 that of 7232, Thus, the energy equivalent to 231 would be (2.36 x 1012)(1.36) = 3.2 x 10" atoms of r* energy equivalent. 131 Thus, ratio of doses ns Z 4.2
