WebbThe activity of a radioactive sample is the number of nuclear disintegrations per second, which is equal to the first-order rate constant times the number of radioactive nuclei present. The fundamental unit of radioactivity is the curie (Ci), where 1 Ci corresponds to exactly $3.70 \times 10^{10}$ disintegrations per second. WebbThe radioactivity of a sample is x at time t_1 t1 and is y at time t_2 t2. If the mean life of the specimen is \tau τ, the number of atoms that have disintegrated in the time interval …

WebbThe activity of a radioactive sample is A 1 at time t 1 and A 2 at time t 2. If τ is average life of sample then the number of nuclei decayed in time ( t 2 – t 1 ) is A. WebbThe radioactivity of a sample is I1 at a time t1 and I2 at a time t2 . If the half-lite of the sample is τ1/2 , then the number of nuclei that have disintegrated in the time t2 - t1 is proportional to Tardigrade Question Physics Q. The radioactivity of a sample is I 1 at a time t1 and I 2 at a time t2 .

WebbThe normal activity of living carbon-containing matter is found to be about 15 decays per minute for every gram of carbon.
