Radioactive decay, also known as nuclear decay or radioactivity, is a random process by which an unstable atomic nucleus loses its energy by emission of radiation or particle. A material containing unstable nuclei is considered radioactive.
Radioactive decay occurs when the nucleus of the original atom is unstable. Since it is unstable it cannot sustain itself, and it breaks down into a... Learn more about this topic: Radioactive Decay | Formula, Types & Examples from
Nuclear decay, also referred to as nuclear radiation, radioactivity, or radioactive decay, occurs when energy in the form of radiation is lost from an atom because its nucleus is unstable. Nuclear decay can occur both naturally and through intentional human activities. Natural sources of nuclear ...

Radioactive Decay:Alpha and beta radioactive decay are two of the four types of decay that occurs when the nucleus of an atom breaks down. The other two types of radioactive decay are gamma-ray emission and electron capture.Answer and Explanation: ...
(Nuclear Physics) disintegration of a nucleus that occurs spontaneously or as a result of electron capture. One or more different nuclei are formed and usually particles and gamma rays are emitted. Sometimes shortened to:decayAlso called:disintegration ...
Once again, the main danger of β radiation comes from when it is ingested in the body.γ radiationAfter the emission of an α particle or β decay, the nucleus is left in an excited state and it releases its excess energy in the form of a γ-ray photon. γ-rays are high-energy ...
Fig. 1. Alpha decay. An example of this decay occurs in the uranium-238 nucleus that decays into thorium-234 nucleus. Alpha particle has a relatively large mass, positive electric charge, and poor radiation penetration, and it can be stopped by a paper sheet (Ilem-Ozdemir and Asikoglu, 20...
(2) Maximum recoil kinetic energy (E K)D=[(E K)D]max=max of the daughter, on the other hand, occurs when either one of the two light decay particles (electron or antineutrino in β − decay; positron or neutrino in β + decay) is emitted with the maximum available kinetic energ...
and electricity generation are beneficial. High-energy particles and waves damage DNA in our cells. When atoms lose high-energy particles and waves, ions or even new atoms can be formed. High-energy waves and particles are called radiation when they leave the atom. The electromagnetic...
