Radiation detection devices

  1. 1.
  2. 2. What is Radiation?<br />Radiation is a process in which energetic particles or energy or waves travel through a medium or space.<br />
  4. 4. What are radiation detection devices?<br />Instruments that can identify the presence of radiation <br />In the environment <br />On the surface of people (external contamination) <br />Inside people (internal contamination) <br />Received by people as exposure<br />Radiation Detection Devices<br />
  5. 5. Devices:<br />Geiger Mueller (GM) Detectors with Pancake Probes<br />Alpha Radiation Survey Meter<br />Dose Rate Meter<br />Personal Dosimeters<br />Newer Radiation Detection Devices<br />
  6. 6. Geiger Mueller (GM) Detectors with Pancake Probes<br />Detects and measures radiation in the environment in real time.<br />
  7. 7. Alpha Radiation Survey Meter<br />Radiation survey meter with probe appropriate for detecting alpha radiation. <br />
  8. 8. Dose Rate Meter<br />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 <br />Provide readings in units of roentgens per unit time (e.g., mR/hr) <br />
  9. 9. Personal Dosimeters<br />A small radiation monitoring device worn by persons entering environments that may contain radiation .<br />
  10. 10. Newer Radiation Detection Devices<br />Multiple functions can be provided by one device <br />- Identify isotopes <br />- Measure dose <br />- Measure dose rate <br />- Alarm for pre-set conditions <br />- Monitor several types of contamination: alpha, beta, gamma <br />Handheld gamma-ray spectrometer<br />Less portable detection device<br />
