What does a dosimeter accurately measure?

• A. The energy of the radiation
• B. The duration of exposure
• C. The amount of radiation a person is exposed to
• D. The type of radiation

Answer: (C)

A dosimeter is designed to quantify how much radiation a person has absorbed over the time they wear it. It converts the energy deposited in their body into a dose value (usually reported in sieverts or millisieverts, sometimes gray for absorbed dose), so you can judge whether exposure stays within safe, regulated limits. The device’s reading reflects the amount of radiation dose accumulated, not the energy of individual radiation events, nor the exact duration of exposure by itself, and it doesn’t independently identify the radiation type (though the dose may be adjusted for different types when reporting dose equivalent). So the best description is that it measures the amount of radiation a person is exposed to.
