is separated into 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 pc
Ba'* — 0.021 yc

Rare Earth Group — 0.030 pc
Others — 0.09 pc

it

The excretion rate of Sr and Ba can be described empirically by a power function, At =
At”? where n is 0.4 and Ay is the activity remaining in the body at time t (days). The ex-

ponent was derived from Cowan,® Sr®® human inhalation data, and it corresponds very closely
