PPT-The Activity :- The activity, defined as the instantaneous number of atoms decaying per

The number of atoms N remaining at a particular instant in time is given by A λ N Where A the activity The traditional unit for activity is called the curie Ci   1 curie 37 x 1010 disintegrations per second .

At the end of each calendar year or at the conclusion of an activity or activities which have been subsidized by EPS, the Student Chapter must submit a report to the EPS Director of Student Programs using the format below for . 53 1 Bq = 1 disintegration per sec. The accepted practice is to give the activity of a radioactive source in becquerel. This is because Bq is the unit chosen for the system of international units ( S uburban P olice A etwork Drug Enforcement Unit Like many communities throughout the United States, Lyndhurst and the Hillcrest area face a growing battle against drugs.
