7. Bell, Carlos G. NUCLEAR LONGE-RANGE FALLOUT IN SURFACE WATERS. (Cont'd. ) As the peak radioactivity concentration in rain and sure face waters occurred about a month after these tests, the Atomic Energy Commission - Civil Defense Administration beta concentration level for 30 day water consumption appears pertinent. This indicates that for drinking water purposes, the Ivy test would have had to discharge (31,000 p curies per milliliter) / (0.02 » » curies per milliliter) = 1,500,000 times as much fission radioactivity to reach the above mentioned level in eastern Massachusetts.
