- Page 57 RADIATION SAFETY This section provides a brief discussion of general radiation safety. The exposure profile for the Model 3216 gauge is also included, along with a discussion of the source encapsulation. X-B-1. TYPES OF RADIATION The radioactive source in the Model 3216 produces three...
- Page 58 (i.e. water, polyethylene, etc.). Neutrons have a neutral charge and are very penetrating. X-B-2. LIMITING EXPOSURE Under normal conditions a full time operator of the 3216 will receive less than 150 millirem per year. Taking advantage available means limit radiation exposure is always recommended.
- Page 59 The current limit in the United States and many other countries is 5,000 millirem per year. Under average conditions a full time employee working with the 3216 will receive less than 150 millirem per year. Anyone working with or near radioactive materials is...
