Radioactive decay is a spontaneous and random process ... but they can use statistical methods to tell when half the unstable nuclei in a sample will have decayed. This is called the half-life.

and the time it takes for one-half of a particular isotope to decay is its radioactive half-life. For example, about 1.5 percent of a quantity of Uranium 238 will decay to lead every 100 million ...

and sugar cubes to simulate the radioactive decay of different isotopes. A radioactive isotope's nucleus is unstable and spontaneously decays, giving off radiation and changing into a different ...

However, when particles decay into other particles—for example, when an atomic nucleus undergoes radioactive decay—CP violation creates a crack in this mirror symmetry. This effect can ...

The radioactive decay is expressed in units called becquerels ... This differs for each radioelement, ranging from fractions of a second to billions of years. For example, the half-life of Iodine 131 ...

Exotic nuclei near and beyond the proton drip line exhibit a range of unique decay processes, including β-delayed proton ...

Example nuclear reactions include radioactive decay, fission, the break-up of a nucleus, and fusion, the merging of nuclei. Measurements of fission fragments for 100 fissioning systems are used to ...

However, when the sample is radioactive ... (i.e., atoms with an unstable nucleus that undergo the radioactive decay process), the researchers developed a new methodology that allows them to ...

For example, most carbon (≈ 99 % ... Stable isotopes do not decay into other elements. In contrast, radioactive isotopes (e.g., 14C) are unstable and will decay into other elements. The less abundant ...

Gamma radiation has no mass and no charge. It can be written as γ or \(_{0}^{0}\textrm{γ}\) An example of beta and gamma decay of cobalt-60 Beta and gamma decay of cobalt-60: ...
