4. What are radiation detection devices? Instruments that can identify the presence of radiation In the environment On the surface of people (external contamination) Inside people (internal contamination) Received by people as exposure Radiation Detection Devices
5. Devices: Geiger Mueller (GM) Detectors with Pancake Probes Alpha Radiation Survey Meter Dose Rate Meter Personal Dosimeters Newer Radiation Detection Devices
6. Geiger Mueller (GM) Detectors with Pancake Probes Detects and measures radiation in the environment in real time.
7. Alpha Radiation Survey Meter Radiation survey meter with probe appropriate for detecting alpha radiation.
8. Dose Rate Meter This survey meter measures environmental levels of penetrating, ionizing radiation May be used to determine whether it is safe to enter an area and, if so, for how long Provide readings in units of roentgens per unit time (e.g., mR/hr)
9. Personal Dosimeters A small radiation monitoring device worn by persons entering environments that may contain radiation .
10. Newer Radiation Detection Devices Multiple functions can be provided by one device - Identify isotopes - Measure dose - Measure dose rate - Alarm for pre-set conditions - Monitor several types of contamination: alpha, beta, gamma Handheld gamma-ray spectrometer Less portable detection device
