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.
Radioactive decay of a radioactive substance or material can be measured by the half-life, which is the time it takes for the radioactive material to decay to half of its original amount. Radioactive decay has three main types of decay: alpha decay (alpha emission), beta decay (positron emission), and gamma emission. It's important to note that there are two types of beta decay: beta minus decay and beta plus decay (positron emission).
