Doctors will order a chloride sweat test for kids with positive newborn screen for cystic fibrosis, a family history of cystic fibrosis, or symptoms of the disorder. Symptoms and signs include failure to grow, repeated lung infections, and digestive problems.
In nuclear physics, beta decay (Î²-decay) is a type of radioactive decay in which a beta ray, and a respective neutrino are emitted from an atomic nucleus.
Beta Decay 1. BETA DECAY. Introduction. Beta particles are positrons and electrons released in a weak nuclear decays. The study of beta-decay spectra led to discovery of the neutrino. This experiment. is concerned with the beta decays of Cs137 and Na22.
