Introduced transmitted intensity

Ray intensity refers to the number of particles emitted by a radionuclide per unit time. The difference from radioactivity is that the former is the number of particles emitted per unit time, and the latter is the number of decays per unit time. There are more than one particle emitted in each decay, and the two nuclides with the same radioactivity have different ray intensity values. For example, a 32P nucleus emits only one β particle, and a 60Co nucleus emits one β particle and two γ photons during one decay. Obviously, the radiation intensity of 60Co nuclides with equal radioactivity is twice as large as that of 32P nuclides.
