WebbThis 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. The Editors of Encyclopaedia Britannica ... WebbThe radioactivity of a sample is R1 at a time T1 and R2 at times T2. the half-life of the specimen is T, the number of atoms that have disintegrated at the time(T2-T1) is … culver creek boarding school
