Question : How radioactive wastes are generated? |
|
Answer» Solution :Radioactive WASTE management involves the treatment, storage, and DISPOSAL of liquid, airborne, and solid effluents from the nuclear industry. Methods of disposal of radioactive wastes are: 1. Limit generation - Limiting the generation of waste is the first and most important consideration in managing radioactive wastes. 2. Dilute and disperse - For wastes having low radioactivity, dilution and dispersion are adopted. 3. 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. 4. 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. |
