Tritium decays via beta emission, which means that it releases a spectrum of low energy electrons from its nucleus. In turn, that radiation can be harnessed to generate small amounts of power, a conversion process known as betavoltaics. . Nuclear battery harnessing light from tube containing phosphor excited by Tritium decay to produce 50-100 nanowatts of energy. This project was created on 07/16/2016 and last updated 9 years ago. 6V at approximately 50 nanoamps. This small, prepurchased tritium tube is pressed against a tiny calculator solar panel and reflector, producing 1. 6V at. . There's this ingenious little hack video: "How to make tritium nuclear battery at home". But why tritium? Why not one of the many other radioisotopes available for nuclear energy applications? The answer lies in a careful balance of safety, efficiency, longevity, and regulatory. .
