What physical property is commonly measured by a dosimeter?

A dosimeter is specifically designed to measure exposure to radiation, making radiation the correct choice. These devices are crucial in environments where individuals may be exposed to ionizing radiation, such as in medical imaging facilities or nuclear power plants.

Dosimeters typically work by measuring the ionization created by radiation as it passes through a material. This allows for the assessment of cumulative radiation exposure over time, which is essential for ensuring the safety of workers in these high-risk environments.

In contrast, the other options focus on different physical properties. Measuring temperature involves thermometers; height is typically measured with measuring tapes or rulers, and sound levels are assessed with sound level meters. Each of these tools serves a distinct purpose, separate from the specific functionality of a dosimeter.
