What is Dosimeter?
A device used to measure an individual's accumulated exposure to ionizing radiation. Types include film badges, thermoluminescent dosimeters (TLDs), and electronic personal dosimeters. Dosimeters are worn by workers in nuclear and medical radiation environments.

Key Facts
Frequently Asked Questions
A device used to measure an individual's accumulated exposure to ionizing radiation. Types include film badges, thermoluminescent dosimeters (TLDs), and electronic personal dosimeters. Dosimeters are worn by workers in nuclear and medical radiation environments.
Dosimeters are mandatory for radiation workers in nuclear facilities, hospitals (radiology, nuclear medicine), industrial radiography, research laboratories, and for emergency responders. They ensure compliance with occupational dose limits (typically 20 mSv/year for workers, 1 mSv/year for public).
Dosimeters are passive safety devices; they do not protect against radiation but record exposure for monitoring purposes. High readings must trigger investigation and corrective action. Dosimeters must be worn correctly (on the torso, facing the radiation source) and regularly processed/calibrated.
The formula or notation for Dosimeter is: Absorbed dose: D (Gy); dose equivalent: H (Sv = Gy × QF)
