WebRadioactive decay and detection. Carbon-14 goes through radioactive beta decay: . 14 6 C → 14 7 N + e − + ν e + 156.5 keV. By emitting an electron and an electron antineutrino, one of the neutrons in the carbon-14 atom decays to a proton and the carbon-14 (half-life of 5,730 ± 40 years) decays into the stable (non-radioactive) isotope nitrogen-14.. As … WebThus we see, a population of N radioactive particles at twould be reduced by half (on average) at time t+t 1/2. Lifetime, or mean lifetime The exponential law can also be interpreted as the decay probability for a single radioactive particle to decay in the interval dt, about t.. This probability, p(t), properly normalized, is given by: p(t)dt ...
