Perhaps two or more unrecognized populations were being tes ed. For
orientation and discussion, I therefore took the median val
e to
represent. the whole group--it would be no more than 30 x 10 6
pCi/day. Among the causes for the wide distribution might le
technical error, but also abnormal or hitherto unrecognized
physiological factors which would be of major interest to d fine.
I would also note that the predicted daily oral intake of
plutonium-239 based on the median urine is .13 picocuries/d , hot
much different from the dietary estimate of .23 picocuries/ ay. The
factor of two tends to parallel the ratio of their cesium
determinations.
