Which of these methods is employed to dispose radioactive waste?
Recycling of radioactive isotopes
Temporary storage of waste to allow natural decay
Geologic disposal underground to reduce radioactivity to natural levels
The correct option is D All of these
Disposal of radioactive wastes is done safely to minimise effects to the environment. Unlike other industrial wastes, the level of hazard of all nuclear waste and their radioactivity, diminish with time. To achieve this, practically all wastes are contained and managed in temporary and permanent burials underground to allow their radioactive decay. Recycling of radioisotopes is also carried out in reprocessing plants and is used for fuel generation.
