WebThis shows that the population decays exponentially at a rate that depends on the decay constant. The time required for half of the original population of radioactive atoms to decay is called the half-life. The relationship between the half-life, T1/2, and the decay constant is given by T1/2 = 0.693/λ. WebWhile it's impossible to know when a radioactive element will decay, it is possible to statistically know the average time it takes for a sample to decay to half of its original amount. This measure, called a half-life, is a crucial measurement in the dating of ancient artifacts and fossils.
