Study Notes
- The text covers radiation and contamination, with contamination including surface and airborne varieties.
- Workplace monitoring is divided into three types: routine, operational, and special.
- Routine monitoring checks that the work environment is satisfactory for continued operations.
- Operational monitoring provides checks on specific operations and allows for immediate decision-making.
- Special monitoring obtains additional information and is carried out in abnormal circumstances.
- Equipment for measuring external radiation includes portable survey meters and stationary monitors, which can be calibrated and have alarm systems.
- Area monitoring techniques involve establishing a layout plan, monitoring for external radiation actively or passively, and following proper measurement procedures.
- Workplace monitoring programs should specify quantities to measure, measurement locations, frequency, methods, and reference levels.
- Contamination monitoring is important in areas prone to radioactive contamination, and includes monitoring for personnel, surface, airborne, and environmental contamination.
- Detectors used for contamination monitoring depend on the type of radiation, with alpha contamination using scintillation-type detectors and beta-gamma contamination using GM detectors.
- Area monitoring methods for surface contamination include direct and indirect methods, with direct methods using portable contamination monitors and indirect methods using smear samples.
- Environmental contamination monitoring ensures that released radioactive materials stay within authorized limits, using both direct and indirect methods.
