The average counting rate of a radioactive sample is around 486 cpm. Determine the probability that in any given 10 second interval one gets less than 72 counts. Is this similar as the probability of getting less than 72 x 6 = 432 counts in about
When radioactive substance provides a counting rate of around 1250 cpm at time t = 0, and a counting rate of 475 cpm at time t = 20 minutes, determine the half life of the substance.
