IV. External Personnel Dosi_metx-y <br />1. Policy <br />Exposures to ionizing radiation will be limited to <br />levels as far below regulatory limits as may be <br />reasonable. This policy will be implemented through <br />a comprehensive personnel monitoring program. <br />2. Program <br />Penetrating and nonpenetrating radiation exposure <br />rates are expected to be very Iow due to the dilute <br />nature of all process materials. None-the-less, <br />personnel monitoring will be provided for all routine <br />facility employees. This program will be divided <br />into two phases: <br />2.1 Routine Monitoring <br />Thermoluminescent Dosimeters (TLD - see technical <br />specifications in Table - 3) will be worn at all <br />times the individual is within the confines of <br />the restricted area. When not in use, TLD <br />badges will be stored on a "badge rack", <br />located in the change room. At least two con- <br />trol badges will be maintained on the badge <br />rack to determine background radiation levels. <br />All personnel and control TLD badges will be <br />exchanged for unexposed badges and forwarded <br />to the vendor each calendar quarter. Net dose(s) <br />will be computed for any personnel badge result <br />exceeding 25% of the applicable limit by sub- <br />tracting the dose received by the personnel <br />badge while stored on the badge rack. <br />10 <br />
