What is the rate of decay? Radioactivity: Some atomic nuclei are unstable, which means they give off radiation. The unstable nuclei are called radionuclides. The specific types of radiation that a nuclei gives off is called radioactive decay. Examples of radioactive decay are alpha particles, be...
The rate of decay can be determined by observing how long it takes for a particular isotope to decay, and then scaling it up to adjust for longer evaluation periods. The half-life of a particular radioactive isotope is a known quantity that can be used to assess the age of an object ba...
The Rate of Decay of Fission Products 来自 Springer 喜欢 0 阅读量: 51 作者: EP Wigner 摘要: There are two ways to describe the total β- and γ-radiation emitted by the fission products. The first, more accurate method describes it as the sum of radiations emitted by the differnt ...
