RADLOLOGICAL SAFETY REGULATIONS
Radiological Defense (Rad-Defense) operations or Radiological
Safety (Rad-Safe) operations, short term Rad-Ops, are general terms,
They are used to denote the means by which a unit can control and confine the damage and radiological effects of an atomic explosion or of
radioactive naterial spread by other moans, thereby preventing and avoiding health hazards to personnel, They are interpreted to include measares
such as training, orgcnizetion, distribution of radiological personnel,
,
development of techniques and procedures, uso of detecting equipment,
protection or removal of exposed personnel and decontamination of personnei
structures and equipment,
b, Following each detonation there will be areas of surface
radiological contamination and areas 6f air radiological contamination,
These areas are designated as Radiological Exclusion Areas (RADEX).
Prior to shot times, the forcast air and surface RADEX will be disseminated
by CJTF SEVEN through CTG 7.2 in the targot area. These RADEXES will represent a forecast from H-Hour until Cisserination of a later surface and
air RADEX at about H plus 4 hours, Since the sir RADEX after shot times
will be based on monitored tracking by aircraft over significant large
ocean areas, information promgated fran the forecast air RADEX my have tc
be extended beyond the originally anticipated.4 hour periods
‘c.
The surface RADEX will be determined by actual survey with
tadlation, detection, indication amd computation (RADLAC) equipment after
shot time.

2. The Maximum Permissible Exposures: (MPa) and Maximum Permissi~
ble Limits QUPLs) as stated herein are applicable to a field experimental
test of nuclear devices in peacetime wherein numbors of personnel employed in these tests have been previously exposed or will be cantinuously
exposed to potentisl radiation hazards, It may become necessary from a
study of personnel records to reduce the MPE for certain individuals who
have recently been over-exposed to radiation, Further, the MPES and MPLs
are subject to revision by waiver from the Task Force Commander in individually designated cases where circumstances indicate the need and justification therefor,
3. Due to the special nature of field tests it is considered that
a policy of strict adherence to the radiological standards prescribed for
routine work is not realistic. The regulations set forth herein have
beon dosigned as a reasonable and safe compromise considering conservation
of personnel exposures, the international import of the test and the cost
aspects of operational delays, chargeable to excessive radiological precautions, In all cases other than emergencies or tactical situations the
ultimate criteria will be limited by the MPEs for personnel, '
‘he
Task Farce radiation dosage control will start on first shot mimus
fifteen (15) days and termimte upon departure of individuals: from the
forward area or the last shot plus fifteen (15) days, Prior and subsequent
to this period, radiation dosage control will be as prescribed by CTC 7.5.
5. a The MPE for personnel involved in this operation, as defined
in paragraph 4, above, is 3.9 roentgens (gamma only). This exposure my
be acquired at anytdns: during a thirteen (13) weck period of the operation,
Provided no previous ovem-cxposure remains for compensation, 345 svouugyis
may de acqujricd without regard to the individual's past radiation history.
This MPE will be considered further augmented (without separate aetion) by
0.3 roentgens per week for each weck in oxcess of thirteen (13) weeks required during the operational period defined by paragraph 4, above,
b,
All exposure to external gamma radiation will be regarded as
total body radiation,
