which of the following personnel radiation monitors will provide an immediate reading

which of the following personnel radiation monitors will provide an immediate reading:

• a. TLD
• b. film badge
• c. lithium fluoride chips
• d. pocket dosimeter.

The answer is d. pocket dosimeter.

Pocket dosimeters are also known as direct-reading dosimeters, self-reading pocket dosimeters, and pocket electroscopes. They provide an immediate reading of an individual's radiation exposure to X-rays and gamma rays.

The other options are all types of passive dosimeters, which must be processed in a laboratory to determine the amount of radiation exposure.

• TLD stands for thermoluminescent dosimeter.
• Film badges use photographic film to record radiation exposure.
• Lithium fluoride chips are a type of passive dosimeter that is more sensitive than film badges.

Therefore, the only personnel radiation monitor that will provide an immediate reading is a pocket dosimeter.
