SAFETY REGULATIONS
1.
The Maximum Permissible Exposure (MPE) for personnel involved in
this operation: is 3.9 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
twenty(20) roentgens, gamma only, is authorized for_crew members of air
sampling aircraft.
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
7
MPE for certain individuals who have participated recently in other atomic
Te
tests. Under a military tactical situation or emergency the maximum -
D
permissible exposures above do not apply.

prior to unrestricted entry.
6.
Rad-Safe monitors assigned to individuals or groups working in
contaminated 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 regulations.
