t. e. In nuclear physics, beta decay (β-decay) is a type of radioactive decay in which an atomic nucleus emits a beta particle (fast energetic electron or positron ), transforming into an isobar of that nuclide. For example, beta decay of a neutron transforms it into a proton by the emission of an electron accompanied by an antineutrino; or ...
Claims are accepted for 30-day unlimited MetroCards and seven-day Express Bus Plus MetroCards purchased with credit or debit cards at an MTA vending machine. The authority will refund part of your ...
Positron emission, beta plus decay, or β+ decay is a subtype of radioactive decay called beta decay, in which a proton inside a radionuclide nucleus is converted into a neutron while releasing a positron and an electron neutrino ( νe ). [1] Positron emission is mediated by the weak force.
Strontium. Strontium-90 is a commonly used beta emitter used in industrial sources. It decays to yttrium-90, which is itself a beta emitter. It is also used as a thermal power source in radioisotope thermoelectric generator (RTG) power packs. These use heat produced by radioactive decay of strontium-90 to generate heat, which can be converted ...

Mineral trioxide aggregate. Mineral trioxide aggregate (MTA) is an alkaline, cementitious dental repair material. MTA is used for creating apical plugs during apexification, repairing root perforations during root canal therapy, and treating internal root resorption. It can be used for root-end filling material and as pulp capping material.
