A dosimeter is used to measure what aspect of radiation exposure for an individual?

• A. Total dose accumulated
• B. Immediate dose rate
• C. Internal contamination
• D. Environmental radiation level

Answer: (A)

A dosimeter is used to track the total amount of radiation a person has received over a period. It records the cumulative dose, which is why it’s worn for personnel monitoring to ensure exposure stays within safety limits. It does not directly measure how rapidly radiation is currently delivering dose (that would be a dose rate reading from another instrument), nor does it assess internal contamination (that requires biological monitoring) or the environmental radiation level around the person (that’s measured by area or environmental monitors). So the key idea is that a dosimeter measures the total dose accumulated by an individual.
