: Average Number Of Radioactive Decays Per Unit Time Rate Or Change In Number Of Radioactive Nuclei Present A Dn 1 (31.77 KiB) Viewed 84 times

: Average Number Of Radioactive Decays Per Unit Time Rate Or Change In Number Of Radioactive Nuclei Present A Dn 2 (11.98 KiB) Viewed 84 times

- Average number of radioactive decays per unit time (rate) or - Change in number of radioactive nuclei present: A= -dN/dt Depends on number of nuclei present (N). During decay of a given sample, A will decrease with time. • Measured in Becquerel (Bq): = 1 disintegration per second (dps) 1 Bq =

dN A= dt - A = total activity N = number of particles t = time
