V. Radiation Surve <br />1. Policy <br />Personnel exposures to ionizing radiation will <br />be limited to levels as far below regulatory limits <br />as may be reasonably achievable. A radiation survey <br />program will be implemented to maintain management <br />cognizence of exposures, hence control of radiation <br />levels. <br />2. Program <br />Excessive levels of beta and gamma radiation are <br />not anticipated due to the dilute nature of all <br />process materials. Non-the-less, a radiation survey <br />program will be implemented in two phases, as de- <br />scribed in the following: <br />2.1 Routine Surveys <br />Monthly measurements of beta and gamma radia- <br />tion levels will be made at the locations <br />shown in Figure 2. These measurements will be <br />made with a beta-gamma dose rate instrument <br />of the type described in Table 3. Investigative <br />surveys will be performed any time that a single <br />reading indicates that personnel will routinely <br />be exposed to gamma radiation dose rates of <br />2.5 mr/hr, or greater. <br />2.2 Investigative and Nonroutine Surveys <br />Investigative and nonroutine surveys will be <br />made at any time it is suspected that exposure <br />12 <br />
