WebRadiation activity is measured in an international (SI) unit called a becquerel (Bq). The becquerel counts how many particles or photons (in the case of wave radiation) are emitted per second by a source. The device used for measurement is often the familiar Geiger counter. If you put a Geiger counter over a gram of substance and count 3 clicks ... WebMay 6, 2024 · A material's radioactivity is measured in becquerels (Bq, international unit) and curies (Ci, U.S. unit). Because a curie is a large unit, radioactivity results are usually shown in picocuries (pCi). A picocurie is one trillionth of a curie. The higher the number, the more radiation released by the material.
