Chapter 5: Radiation Monitoring
| Term | Definition |
|---|---|
| dosimeter provided by the monitoring company with each batch of dosimeters to serve as a basis for comparison with the remainder of the dosimeters after they have been returned for processing; determines if batch of dosimeters has been exposed in transit | control monitor |
| a device that monitors the equivalent dose of radiation to the hands | extremity dosimeter |
| a device that detects individual radioactive materials emitting photons and/or electrons and that also serves as the primary portable radiation survey instrument for area monitoring in nuclear medicine facilities | Geiger-Muller (GM) survey meter |
| a graphic plot that demonstrates the relationship of light output to temperature variation for a thermoluminescent (glowing upon heating up) (TL) material, such as is used in a TL dosimeter (TLD) | glow curve |
| this instrument is both a rate meter device used for area surveys and an accurate integrating or cumulative exposure or dose measurement instrument for x-radiation and gamma radiation and, if equipped with a suitable window, for recording beta radiation | ionization chamber-type survey meter (cutie pie) |
| a device for monitoring occupational exposure containing aluminum oxide detector. The dosimeter is "read out" by a laser light at selected frequencies. Laser light becomes luminescent in proportion to amount of radiation exposure received | optically stimulated luminescence (OSL) dosimeter |
| a small ionization gas filled dosimeter connected to a "solid-state" device, with electrically erasable programmable read-only memory (EEPROM) | personnel direct ion storage dosimeter (DSI) |
| a personnel device that determines occupational exposure by detecting and measuring the quantity of ionizing radiation to which the dosimeter has been exposed over a period of time | personnel dosimeter |
| refers to the monitoring of equivalent dose to any person occupationally exposed on a regular basis to ionizing radiation | personnel dosimetry |
| a written report of occupational radiation exposure of personnel prepared by a monitoring company | personnel monitoring reports |
| a radiation survey instrument generally used in a laboratory setting to detect alpha and beta radiation and small amounts of other types of low-level radioactive contamination | proportional counter |
| area monitoring devices that detect and/or measure radiation levels as well as radiation exposure rates | radiation survey instruments |
| personnel monitoring device that most often contains a crystalline form of lithium fluoride as its sensing material; when placed in a TLD analyzer and heated, the crystals emit visible light in proportion to the amount of radiation the ring was exposed to | thermoluminescent ring dosimeter |
