Becquerel
subjectfact 
Becquereldocumentation SI ActivityMeasure. Symbol: Bq. It measures the amount of radioactivity contained in a given sample of matter. It is that quantity of a radioactive element in which there is one atomic disintegration per SecondDuration. Becquerel = s^(-1)2001-11-30 13:33:41.0
