WebDetecting & Measuring Radiation Radiation has no odor or property that allows it to be seen. However, there are many types of devices used to measure it. Some devices are qualitative—they simply tell you that radiation is present but don’t tell you the amount of radiation present or the amount of exposure you are receiving. WebHow electromagnetic radiation is detected and measured To measure the intensity of incoming electromagnetic radiation, remote sensing instruments rely on special materials that are efficient absorbers of radiation with the desired range of wavelengths, and that generate an electrical current when exposed to radiation – a current which is then … WebThe filter is a slowly moving strip and is measured by a radiation detector.
