Radioactive waste is any waste that contains radioactive material. Radioactive (or nuclear) waste is a byproduct from nuclear reactors, fuel processing plants, hospitals, various industrial applications and research facilities. Radioactive waste is hazardous to most forms of life and the environment, and is regulated by government agencies in order to protect human health and the environment.
Intermediate-level waste (ILW) contains higher amounts of radioactivity and it generally require shielding, but the heat it generates (<2 kW/m3) is not sufficient to be taken into account in the design or selection of storage and disposal facilities.
Intermediate-level wastes includes ion-exchange resins, chemical sludge, contaminated materials from reactor decommissioning and some radioactive sources used in radiation therapy. Intermediate-level radioactive waste that requires long-term management. The owners and the producers of intermediate-level radioactive waste are responsible for managing the waste they produce. It may be solidified in concrete or bitumen for disposal. As a general rule, short-lived waste (mainly non-fuel materials from reactors) is buried in shallow repositories, while long-lived waste (from fuel and fuel reprocessing) is deposited in geological repository.
