Chapter 5 Key Terms

3. A personnel monitoring device that most often contains a crystalline form of lithium fluoride as its sensing material
5. A small ionization gas filled dosimeter connected to a "solid state" device, with electrically erasable programmable read-only memory
6. 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 suitable window, for recording beta radiation as well
8. The monitoring of equivalent dose to a any person occupationally exposed on a regular basis to ionizing radiation
9. A written report of occupational radiation exposure of personnel prepared by a monitoring company
11. A 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
12. Area monitoring devices that detect and/or measure radiation levels as well as radiation exposure rates
13. A device that monitors the equivalent dose of radiation to the hands

1. Serves as the primary portable radiation survey instrument for area monitoring in nuclear medicine facilities
2. 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
4. A device for monitoring occupational exposure that contains an aluminum oxide detector
7. 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 to the monitoring company for processing
10. A graphic plot that demonstrates the relationship of light output to temperature variation for a thermoluminescent material, such as is used in a TL dosimeter
