is separated int its components using the ratio of individual isotope activities in the urine or
in the total body of the animals at this time, the following values for the Rongelap group, 82
days post-detonation were obtained:
Sr®* — 0.19 pe
Ba !#° _ 9.022 pc
Rare Earth Group — 0.030 uc
Others — 0.09 ye
The excretion rate of Sr and Ba can be described empirically by a power function, Ay =
A,t7® where n is 0.4 and A; is the activity remaining in the body at time t (days). The ex-
ponent was derived from Cowan, Sr*’ humaninhalation data, and it corresponds very closely
