RADIOLOGICAL SAFETY REGULATIONS
lo
The Maximum Permissible Exposure (MPE) for personnel involved in this
operation is 369 roentgens, gamma only, unless reduced because of
previous or anticipated future exposure. All exposure to external
gamma radiation will be regarded as total body irradiation. Special
MPE of 20 roentgens, gamma only, is authorized for crew members of
air sampling aircrafte The maximum permissible exposures as stated
above are applicable to a field experimental test of nuclear devices
in peacetime, wherein numbers of personnel engaged in these tests
have been previously exposed or will be continuously exposed to potential radiation hazards. It may become necessary from a study of
personnel records to reduce the MPE for certain individuals who have
participated recently in other atomic testse
Under a military tacti-
cal situation or emergency the maximum permissible exposures above do
not applye

Contaminated land areas of intensities less than 10 mr/hr will be considered unrestricted from a RadSafe viewpoint.
Areas coming within
this limitation will be designated specifically by CJTF SEVEN prior
to unrestricted entry.
RadSafe monitors assigned to individuals or groups working in con-
taminated areas or with contaminated equipment during recovery operations will act in an advisory capacity to keep the recovery party
leader informed of radiation intensities at all times. The recovery
party leader is expected to accept this advice and act accordingly.
It is the responsibility of both the leader and the members of the
recovery party to adhere to the limits established in these regulationse
