In planning operations involving exposure to ra-diation, no individual should be exposed to aver-age levels exceeding 0.1 of the MPDE or MPC.
3.
The external exposure of an individual in any one week r,hould not exceed:
a) 7.00 mrem to whole body, head and trunk, gonads, lens of eye and active blood-forming organs.
b) 1500 mrem to extremities.

The average daily concentration for airborne expo-sure should not exceed:
Natural Uranium 1 x J0-10 ja Ci/ml Uranium-235 1 x 10-10 ja Ci/ml No allowances shall be made for the use of respi-ratory equipment unless approved in advance by the GAC Radiation Protection Officer.
B.
Ununual Occurrences An unusual occurrence is a term used to denote an oper-ational incident involving ionizing radiation.
When an unusual occurrence has taken place in the project facility, the GAC Radiation Protection Officer shall br informed promptly.

Any lunch room facility provided for project per-sonnel shall be surveyed routinely for indication of radioactive contamination.
D.
Personnel Exposur Control 1.
Only authorized personnel shall be permitted to participate in enrichment project activities in-volving radiation exposure exceeding 1/10 of the MPDE and MPC.
An individual shall not be authorized as a radiation worker if:
a)
He has an accumulated occupational dose ex-ceeding the recommended maximum limits.
b)
He has a documented non-occupational dose sig-nificantly exceeding the recommended occupa-tional limits.
c)
He has certain physical limitation.s specified by the Corporate Occupational Health Services Department.

2.
The Program Director shall be aware of the radi-ation dose status of all personnel under his supervision and shall approve entry of personnel into a radiation area or contamination zone.
3.
Project areas in which an actual or potential radi-ation hazard exists shall be posted or zoned and provided with instrumentation necessary +a warn individuals of significant increases in uatoid potential.
4.
Guidelines for emergency protective action for ex-posure to identified airborne contaninants are as follows:
Concentration Range Immediate Protective Action
~
MPCa None 1-100 MPCa Full face mask or evacuation.
100 MPCa Supplied air or evacuation.
E.
Contamination Control Zone A contamination zone shall be established whenever it becomes evident that personnel, equipment or the envi-rons are subject to becoming significantly contaminated with radioactive materials.
Table IV shall be used as a guide in determining contaaination zones.
