Nuclear waste half life
All radionuclides contained in the waste have a half-life — the time it takes for half of the atoms to decay into another nuclide. Eventually, all radioactive waste decays into non-radioactive elements (i.e., stable nuclides). Since radioactive decay follows the half-life rule, the rate of decay is inversely proportional … Meer weergeven Radioactive waste is a type of hazardous waste that contains radioactive material.
