Which device measures radiation exposure?

• A. Radiograph
• B. Dosimeter
• C. Collimator
• D. Developer

Answer: (B)

The device that measures radiation exposure is a dosimeter. A dosimeter is specifically designed to quantify the amount of ionizing radiation that a person is exposed to over a given period of time. It functions by capturing and storing dosimetric data that can later be read to determine the radiation dose received. This is crucial in settings such as dental practices where radiation is used, as it helps ensure that radiological safety protocols are adhered to and that staff and patients are not exposed to harmful levels of radiation. Regular monitoring through dosimeters allows for effective assessment and management of exposure, which is a key aspect of maintaining safety in a radiology environment. The other options function differently: a radiograph is a picture created using X-rays, a collimator is used to restrict the size and shape of the X-ray beam, and a developer is a chemical solution used to process radiographic film. While all might be related to the use of radiation in imaging, they do not measure radiation exposure directly.
