Which device is used to measure radiation exposure to personnel?

Question

Question

Answer 1

Correct Answer: Dosimeter

Rationale:

A dosimeter is a device used to measure an individual's exposure to ionizing radiation over a period of time. It is commonly worn by personnel working in environments where they may be exposed to radiation, such as in medical, nuclear, or industrial settings.
Dosimeters can provide real-time monitoring and cumulative dose measurement, ensuring that the radiation exposure remains within safe limits as prescribed by regulatory bodies.
There are different types of dosimeters, including thermoluminescent dosimeters (TLDs), optically stimulated luminescence (OSL) dosimeters, and electronic personal dosimeters (EPDs), each with specific applications and levels of precision.

Explanation of Other Options:

Geiger counter

Rationale: A Geiger counter is an instrument used for detecting and measuring ionizing radiation. It is more commonly used to detect the presence and intensity of radiation in an area rather than for personal exposure monitoring. Geiger counters are not typically used for measuring cumulative radiation exposure to personnel.

X-ray detector

Rationale: An X-ray detector is a device used to measure the intensity and pattern of X-rays for imaging purposes. It is primarily used in medical diagnostics and industrial inspection, not for monitoring personal radiation exposure over time.

Ionization chamber

Rationale: An ionization chamber is a device used to measure the quantity of ionizing radiation by collecting the charge created by ion pairs in a gas. While it is used for measuring radiation, it is typically used for surveying and measuring radiation in an area rather than for personal dosimetry.

Conclusion:

Among the given options, the dosimeter is the correct device for measuring radiation exposure to personnel. It is essential for ensuring the safety of individuals working in environments with potential radiation exposure by providing accurate and cumulative exposure data.
