Radiation Quantities and Units of Ionizing Radiation

One becquerel is an extremely small amount of radioactivity. Commonly used multiples of the Bq unit are kBq (kilobecquerel), MBq (megabecquerel), and GBq (gigabecquerel). 1 kBq = 1000 Bq, 1 MBq = 1000 kBq, 1 GBq = 1000 MBq. An old and still popular unit of measuring radioactivity is the curie (Ci).
