78 , EFFECTS OF IONIZING RADIATION activity was obtained in total d/m, and was converted to pe “Co™equivalent.” Samples were analyzed radiochemically for Sr, Bal, the rare earth group, I"! and fissile material. Forexcretion studies, the animals were caged individually, and their excreta collected at 24hour intervals. The feces and urine of chick- ens were collected and ashed combined, but were collected and ashed separately for the pigs. Beginning 5 weeks post detonation, the excreta of a representative group of chickens was col- lected at weekly intervals for a period of 21% months. Collection of pig excreta was begun at 6 weeks post detonation, andthe collection was made at weekly intervals for a 6-week pe- Table 5.8.—Radiochemical Analysis of Tissues and Urine of Pigs From Rongelap on 82nd Day Post-Detonation BETA ACTIVITY —D/M/TOTAL SAMPLE SAMPLE Pig #24 (25.8 kgm) Gross ov rte x10 8890 Liver____.___-.-.-_-______-_ Colon & Contents. _._. 2 2. 31 12 1 1. 0. 22 0. 22 0. 20 1. 1 0.8 1.3 Intestine (Small)____-2 222.
