How is radiation typically measured?

Radiation is typically measured using instruments specifically designed to detect and quantify ionizing radiation, which include devices like a Geiger-Müller counter or dosimeter. A Geiger-Müller counter is particularly common for its ability to provide immediate results by clicking or blinking in the presence of radiation, indicating both the presence and intensity of radiation. Dosimeters, on the other hand, are used to measure the amount of radiation exposure over time, often worn by individuals working in environments where radiation may be present.

These tools are crucial in ensuring safety in environments such as nuclear power plants or medical facilities that utilize radiation, as they help monitor and manage exposure to prevent harmful effects.

In contrast, a thermometer measures temperature, a radiation spectrometer is more specialized for identifying the type and energy of radiation rather than just measuring it, and an infrared sensor is not appropriate for detecting ionizing radiation at all.
