What type of radiation is mainly measured by personal dosimeters?

Personal dosimeters are devices designed to measure an individual's exposure to radiation, which encompasses a variety of radiation types, including gamma rays, X-rays, and neutrons. However, the primary purpose of these dosimeters is to assess individual exposure levels rather than measuring specific types of radiation.

The emphasis on individual exposure makes this choice particularly relevant because personal dosimeters provide critical data for monitoring radiation levels that workers or individuals may encounter in environments where radiation is present. This monitoring allows for effective safety measures to be implemented and ensures compliance with safety regulations, thereby protecting individuals from potential harm caused by radiation exposure.

While gamma rays and X-rays are commonly monitored, they are subcategories of the overall concept of personal exposure. This distinction is vital in understanding the comprehensive role of personal dosimeters in radiation safety.
