Explainer: the difference between radiation and radioactivity Radioactivity is the decay or rearragement of an atom’s nucleus. Radioactivity is the term given to the breaking-up (decay) or rearrangement of an atom’s nucleus. Decay occurs naturally and spontaneously to unstable nuclei. This instability is usually caused by a mismatch between the number of protons and neutrons.

Glossary of Common Wafer Related Terms Resistivity - The resistance that a unit volume of a material offers to the passage of electricity, the electric current being perpendicular to two parallel faces. More generally, the volume resistivity is the ratio of the potential gradient parallel with the current in the material to the current density.

Property Information Property Information Resistivity Overview. Resitivity is a measure of the resistance to electrical conduction for a given size of material. Its opposite is electrial conductivity (=1/resistivity). Metals are good electrical conductors (high conductivity and low resistivity), while non-metals are mostly poor conductors (low conductivity and high resistivity).
