WebAnswer (1 of 3): The activity (A) and the no of nuclei are related by A= λN where λ is the decay constant and N the number of nuclei. The decay constant is found by λ =ln(2) /t(1/2) where t(1/2) is the halflife. The activity is in Bq which is disintegreations per second so I would start by conv...
