Radiation detection devices are instruments that can identify the presence of radiation in the environment, on surfaces, inside or outside of people. Some common radiation detection devices include Geiger Mueller detectors with pancake probes, which detect and measure radiation in real time, alpha radiation survey meters for detecting alpha radiation, and dose rate meters that measure environmental radiation levels and determine safety. Personal dosimeters are worn to monitor radiation exposure, while newer devices can identify isotopes, measure dose and dose rate, and monitor multiple contamination types.

2. What is Radiation?Radiation is a process in which energetic particles or energy or waves travel through a medium or space.

7. Alpha Radiation Survey MeterRadiation survey meter with probe appropriate for detecting alpha radiation.

8. Dose Rate MeterThis 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 DosimetersA small radiation monitoring device worn by persons entering environments that may contain radiation .

10. Newer Radiation Detection DevicesMultiple 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 spectrometerLess portable detection device
