ZAP ENERGY ZRD-SPL-001 1.3 Zap Energy Radiation Protection Policy and Dose Limits In the current research and development phase, Zap Energy treats the personnel involved with the operations of the fusion devices,which include the operators and the physicists(called"operators' hereafter), as individual members of the public for their occupational dose limit. Therefore, the total effective dose equivalent to the individuals of the operators shall not exceed 100 mrem in a year, exclusive of the dose contributions from background radiation, from any medical administration the individual has received, from exposure to individuals administered radioactive material and released under chapter 246-240 WAC, from voluntary participation in medical research programs, and from the licensee's or registrant's disposal of radioactive material into sanitary sewerage in accordance with WAC 246-221-190. 1.4 Occupancy Factors and Dose Limits for Shielding Design The general classification of the areas and their occupancies are listed in Table 1 and more details for each specific location are listed in Table 2. The classification of the areas and their occupancy factors are referenced from the NCRP Report No. 144 [1] and the NCRP Report No. 147 [2]. The dose limits for shielding design are the annual dose limit divided by the occupancy, which are provided in Table 1 for general area classifications and Table 2 with more details. Dose limit for Shielding Design = Annual Dose Limit(100mrem/yl 1 Occupancy The doses for each area shall not exceed the shielding design dose limits .
