Question

11- What are radioactive wastes, harmful effects and disposal methods of radioactive wastage?

Answer 1

Answer:

Radioactive waste is a type of hazardous waste that contains radioactive material. Radioactive waste is a by-product of various nuclear technology processes. Industries generating radioactive waste include nuclear medicine, nuclear research, nuclear power, manufacturing, construction and nuclear weapons reprocessing.

The disposal methods for nuclear waste most used is simple storage. For example, dry cask storage uses steel cylinders along with inert gas or water to seal and store radioactive waste from spent fuel pool. ... The radioactive waste can be easily stored at a on-site reactor facility or adjacent to the source reactor.

Answer 2

$\Huge\blue{ a) }$ $\sf\underline\pink{ Radioactive~Waste~Disposal}$ $\huge\bold\green{ :- }$

1. Initially, nuclear energy was hailed as a non-polluting way for generating electricity.
2. Later on it was realised that the use of nuclear energy has two serious problems. (i) Accidental Leakages (ii) Safe Disposal
3. Radiation, that is released from nuclear waste is extremely dangerous to biological organisms, because it induces mutations.
4. Exposure to high doses of nuclear radiation is lethal as it can lead to cancers. (Ex :- Leukemia).
5. So, nuclear waste is an extremely potent pollutant and has to be dealt with utmost caution.
6. Storage of nuclear wastes should be done in suitably shielded containers and buried deep in the soil or oceans about 500 meters depth.
