Description/Abstract:
The memo talks about continuous discussions between Dr. Lum and H.L. Friedell about the tolerance levels for Polonium. The discussion also mentions recommended levels that could interfere with production. It is reported in the letter that Dr. Lum indicated that the present inventory of Polonium in the Dayton plant will permit deliveries of Polonium to Y at the scheduled rate unitl the middle of May. This could be accomplished uder the adoption on 1 April, 1946 of a tolerance of 500 disintegrations per minute per daily urinary excretion. After the middle of May the production rate would drop to about 1/3 of the present rate, but it is expected that the provision of hoods and more careful operating procedures will permit production to rise probably to the present level by 1 July.
