What type of device measures the radiation dose received by a radiographer?

A personal dosimetry device is specifically designed to measure and record the amount of ionizing radiation exposure that an individual, like a radiographer, receives over time. These devices are worn on the body, typically in areas where radiation exposure is most likely to occur, such as on a badge worn on the chest. They are crucial for monitoring occupational exposure to ensure that it remains within safe limits as set by health and safety regulations.

Personal dosimetry devices provide detailed information that helps in assessing the risk faced by radiographers and other workers in radiation environments. This data assists in maintaining safe working conditions and instituting measures that might be necessary to reduce exposure when high levels are detected.

In contrast, environmental survey devices are used to assess radiation levels in a given area, radiation detectors can identify the presence and type of radiation but may not provide a measure of personal exposure, and equipment survey devices typically evaluate the functionality and safety of radiological equipment itself, rather than measuring dose received by individuals.
