Radioactive Waste Storage, Conditioning and Disposal
Background
Radioactive sources ( radioactivity obtained by man made materials ) are used worldwide in medicine, industry and research for a wide range of applications. At the end of their useful life usually 5-15 years the radioactive sources are termed as "spent" or "used up". Most of these waste (spent sources ) are to some extent radioactive.
They are thus potential sources of radiological impact; both radiation workers and members of the public who may be exposed if the spent sources are released into the environment.
Radioactive waste may occur in any of the 3 physical forms solid, liquid and gas. Storage nd disposal methods will vary according to the form of the waste, the radio nuclides present ( i.e the half life), their concentration and radio toxicity.
AERE has a Central Waste Processing and Storage Facility, where user from the commerce and industry can ask AERE to provide the service of indefinite storage . This is again done at a cost . the cost of storage space and others. The rate is given in the list below.
