Webgamma ray, electromagnetic radiation of the shortest wavelength and highest energy. Gamma rays are produced in the disintegration of radioactive atomic nuclei and in the decay of certain subatomic particles. … WebRadiation cure is used on a range of products, including coatings for plastics and wood flat stock: doors, paneling, flooring, etc. In most cases, the wet coatings contain no solvent (100% solids). They cure rapidly, and the cured films have outstanding toughness and scratch resistance.
Because of their high energy, gamma rays are ionizing, meaning they can dislodge electrons from atoms, ultimately damaging living cells and causing a hazard to health. However, as with all radiation, it depends upon the dose that you receive. In small doses, very carefully targeted to limit exposure, they can be … See more At the turn of the twentieth century, two forms of radiation emitted by decaying atoms were known, namely alpha particles (which are helium nuclei) and beta particles (which are electronsand positrons).
