HALF-LIFE CALCULATOR

WebbSolution For The activity of a radioactive sample is A1 at time t1 and A2 at timet2. If τ is average life of sample then the number of nuclei decayed in time (t2−t1) is WebbThe activity of a sample is directly proportional to the number of atoms of the radioactive isotope in the sample: (5) A = k N Here, the symbol k is the radioactive decay constant, which has units of inverse time (e.g., s −1, yr … canada community business college login

SOLVED: The radioactivity of a sample is R1 at a time T1 and R2 at …

WebbThe answer can be found by examining Figure 1, which shows how the number of radioactive nuclei in a sample decreases with time. The time in which half of the original number of nuclei decay is defined as the half-life, t1/2. Half of the remaining nuclei decay in the next half-life. Further, half of that amount decays in the following half-life. http://www.1728.org/halflife.htm WebbIf A1 and A2 are its activities at times t1 and t2 respectively, the number of nuclei which have decayed during the time t1 – t2.
