👉 A microradiometer is a device used to measure the radiation intensity of a material. It consists of a thin, highly sensitive metal plate or semiconductor crystal that is illuminated by an ultraviolet light source and then detected using a photodiode or other electronic detector. The key advantage of this type of instrument is its sensitivity to very low levels of radiation, making it useful for measuring small amounts of radiation in microgravity environments where the radiation level can be difficult to measure accurately with traditional radiometers.
