The rate of decay per gram of radioactive sample is its specific activity. Specific activity can be calculated by knowing the number of particles emitted per second and from the mass of sample. Disintegration per second is known as becquerel. Disintegration can be either alpha, beta, or decay. One alpha particle emission is equal to one disintegration. Specific activity =((7.4x10^4 days/60 sec)/ (8.58ug x 10^-6 g))(1 Ci/3.70x10^10 dps) = 1.4x 10^8 Bq/g
