Active Dosimeter

An active dosimeter is used in Dosimetry to measure Radiation exposure, usually to individuals. Being active, the dosimeter can provide real-time instant information about radiation Dose and Dose Rate. See EPD for more specific information on devices, and Passive Dosimeter for information on alternative passive detection methods.

Physics is really nothing more than a search for ultimate simplicity, but so far all we have is a kind of elegant messiness
