HAR §11-45-14. Units of radioactivity

For purposes of these rules, activity is expressed in the SI unit of becquerel (Bq) or in the special unit of curie (Ci), or their multiples, or disintegrations or transformations per unit of time: (1) One becquerel (Bq) = one disintegration or transformation per second (s-1). (2) One curie (Ci) = 3.7 x 1010 disintegrations or transformations per second = 3.7 x 1010 becquerel (Bq) = 2.22 x 1012 disintegrations or transformations per minute.
