Note 7 (cont.) The normally (a) (b) (c) (d) distribution distributed: of the 30 x 10-s Below 30 500 999 - data pCi/day supplied (the by Dr. method’s Lessard limit) was not = 19 = 11 499 999 3400 =2 = 3 were being tested. I Perhaps two or more unrecognized populations the whole group--which therefore took the median value to represent would be no more than 30 x 10-6 pCi/day. Among the causes for the wide distribution might be technical error, but also abnormal or hitherto define. unrecognized physiological factors which would be of interest I would also note that the predicted daily oral intake of plutonium-239 based on urine is .13 picocuries/day, not much different from the dietary estimate of .23 picocuries/day. The factor of two tends to parallel the ratio of their cesium determinations. (The activity radio plutonium-240/plutonium-239 0.6.)
