ATOMIC ENERGY COMMISSION
RADIOLOGICAL SAFETY CRITERIA FOR THE
NEVADA TEST SITE
Report to the General Manager by the
Director of Biology and Medicine
THE PROBLEM
1, To establish radiological safety criteria for exposures
to gamma radiation from fallout to populations around the Nevada
Test Site,
SUMMARY
2, The trend in thinking of the International Commission
on Radiation Protection, the National Committee on Radiation
Protection, and the National Academy of Sclerce is toward more
restrictive criteria for standards of radiation protection,
3. In light of the above, it is recommended thet radiological safety criteria for exposures to gamma radiation from fallout
to populations around the Nevada Test Site should be as follows:
a. The current crlterion of 3.9 roentgens for any
one year; plus an additional restriction of
b. 10 roentgens in a period of 10 years, with the
first of the successive ten-year periods starting in
the spring of 1951,
4, These should be construed to be operational guides
rather than maximum permissible limits, since exposures somewhat
in excess would not be hazardous.
