<prompt> 1 becquerel is equal Disinegrationsec to:3.7x10102.7x10101.7x10101  <response>: D i.e. 1 Becquerel Bq or disintegration per second is the SI unit of radioactivity wherea Curie Ci is non-SI unit of radioactivity. The rate of radioactive decay of a sample is called radioactivity. SI unit of activity is the Bequerel Bq, defined as one nuclear disintegration per secondQ. The Curie Ci is defined as 3.7x1010 disintegrations per second, thought to be the number of disintegrations found in 1 gin of radium.
