A dosimeter is worn to monitor what?

• A. Temperature
• B. Humidity
• C. Pressure
• D. Radiation exposure

Answer: (D)

A dosimeter is worn to monitor the amount of ionizing radiation a person has been exposed to over a period of time. This helps ensure occupational exposures stay within safety limits and supports ALARA, keeping exposures as low as reasonably achievable. By recording cumulative dose, it guides shielding decisions, work practices, and the need for additional dose-reduction measures. There are several types of dosimeters, including film badges, thermoluminescent dosimeters (TLDs), optically stimulated luminescence (OSL) devices, and electronic personal dosimeters that can provide real-time readings. None of these devices measure environmental conditions like temperature, humidity, or pressure, which are tracked by separate sensors. The key point is that a dosimeter’s purpose is to quantify radiation exposure, not environmental factors.
