What equipment is used to measure radiation dose?

The dosimeter is the appropriate equipment used to measure radiation dose. It is specifically designed to assess the amount of ionizing radiation exposure that an individual has received over a period of time. Dosimeters can come in various forms, including personal dosimeters, which are worn by individuals working in radiologic settings, and area dosimeters, which monitor radiation levels in specific locations.

These devices typically use materials that react to radiation exposure in a measurable way, often employing thermoluminescent or optically stimulated luminescent technologies. This capability allows for accurate tracking of accumulated radiation dose, which is crucial for ensuring safety and compliance with radiation exposure limits in medical, industrial, or research environments.

In contrast, while transducers are used for converting one form of energy into another, such as in ultrasound applications, they do not measure radiation dose. Geiger counters are designed to detect and measure ionizing radiation but are more suited for monitoring and detecting radiation presence rather than quantifying absorbed dose. Radiographic film serves as a recording medium for images produced by X-rays but does not provide a direct measure of radiation dose received by an individual.
