Lifetime measurement. The activity (in decays per second) of some radioactive samples varies in time in a particularly simple way. If the activity (R) in decays per second of a sample is proportional to the amount of radioactive material (R [alpha] N, where N is the number of radioactive nuclei), then the activity must decrease in time exponentially … 2, record 1, English, - lifetime%20spectrum
