wastes are

wastes are . Limit generation - Limiting the generation of waste is the first and most important consideration in managing radioactive wastes. . Dilute and disperse - For wastes having low radioactivity, dilution and dispersion are adopted. . Delay and decay - Delay and decay is frequently an important strategy because much of the radioactivity in nuclear reactors and accelerators is very short lived. . Concentrate and confine process - Concentrating and containing is the objective of treatment activities for longer- lived radioactivity. The waste is contained in corrosion resistant containers and transported to disposal sites. Leaching of heavy metals and radionuclides from these sites is a problem of growing concern.
