Nuclear Energy Batteries

An atomic battery, nuclear battery, radioisotope battery or radioisotope generator uses energy from the decay of a radioactive isotope to generate electricity. Like a nuclear reactor, it generates electricity from nuclear energy, but it differs by not using a chain reaction. Although commonly called batteries, atomic batteries. . Thermionic conversionA consists of a hot electrode, which thermionically emits electrons over a space-charge barrier to a cooler electrode, producing a useful power output. . Medtronic and Alcatel developed a , the Numec NU-5, powered by a 2.5 Ci slug of plutonium 238, first implanted in a human patient in 1970. The 139 Numec NU-5 nuclear pacemakers implanted in the 1970s are expected to. . In the field of microelectromechanical systems (), nuclear engineers at the have explored the possibilities of producing minuscule batteries which exploit radioactive nuclei of substances such as polonium or curium to. . • • • • - TFOT article . Non-thermal converters extract energy from emitted radiation before it is degraded into heat. Unlike thermoelectric and thermionic converters their output does not depend on the temperature difference. Non-thermal generators can be classified by the type of. . Atomic batteries use radioisotopes that produce low energy beta particles or sometimes alpha particles of varying energies. Low energy beta particles are needed to prevent the production of high energy penetrating radiation that would. . • – Small battery• – Bombarding atomic nuclei to give off very short-wavelength light• • – Type of spacecraft propulsion system
