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.
If the beta decay is negative, it means that an electron is emitted from the atom, then a neutron has to be converted to a proton, and the atomic number is increased by one, changing the atom to a new element; the isotope number stays the same, but the mass of the atom is reduced.f the beta decay is positive, it usually means a proton is turned into a neutron by capturing an electron from the atom's innermost shell; this reduces the atomic number by one, changing the element, but the isotope number stays the same and the emission is a neutrino.
