Scientific & EducationalDisintegration of atomic nuclei resulting in the emission of alpha or beta particles (usually with gamma radiation). Also the exponential decrease in radioactivity of a material as nuclear disintegrations take place and more stable nuclei are formed.
Scientific & EducationalA number that describes the dielectric strength of a material relative to a vacuum, which has a dielectric constant of one. Relative permittivity. It is the ratio of the capacitance of a capacitor with the given material as dielectric, to the capacitance of the same capacitor with vacuum (or air) as the dielectric. That property of a dielectric that determines the electrostatic energy stored per unit volume for a unit potential gradient.
