38 Note 7 (cont.) The urine data supplied by Dr. Lessard were not normal! Y distributed: (a) Below 30 x 10-® pCi/day (the method's limit) = 19 (b) 30 - 499 = ll (c) 500 - 999 = 2 (d) 999 - 3400 =z 3 ersons ersons ersons ersons 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. 0.6.) (The activity ratio plutonium-240/plutoniun- 239 is I understand that DOE is formulating plans to look int« the matter.
