Which of the following is not listed among the three types of personal radiation monitors?

• A. OSL dosimeter
• B. Thermoluminescent dosimeter
• C. Personal Digital Ionization Chamber
• D. Scintillation counter

Answer: (D)

Personal radiation monitors are designed to measure the dose a worker receives, either passively or in real time. The two main groups are passive dosimeters, like OSL dosimeters and thermoluminescent dosimeters, which record dose for later reading; and active dosimeters, such as a personal digital ionization chamber, which provide immediate, ongoing dose information. A scintillation counter, although a versatile detector for environmental monitoring and radiation measurements, is not worn by a worker to accumulate dose. Therefore it is not considered a personal monitor.
