Radon detection tests are made to detect radon gas in picocuries per liter of air (pCi/L). The picocurie is utilized to determine the magnitude of radiation in terms of fragmentations per min. One pCi, one trillionth of a Curie, equates to 2.2 fragmentations per min. The most common geologic resource of radon originates from the decay of uranium. Radon is commonly discovered at reduced degrees in widely spread crustal developments, dirt, as well as water samples.
