Radioactive waste
Radioactive wastes are by-products of using radioactive materials in various field such as nuclear power generation, mining, medicine, defense and research field. They are basically radio nucleotide of higher concentration than the allowed limit by regulatory authorities.
Types of radioactive waste:
Based on the level of radioactivity, International Atomic Energy Agency (IAEA) has classified radioactive waste into 4 categories:
- Exempt waste: The waste which meets criteria for exclusion or exemption from regulatory authority is called exempt waste. The radioactivity of these waste are very low.
- Low-level waste: They are contaminated waste from industries, hospitals and research field. These waste includes paper, toys, tools, clothing and filters, they get contaminated once they come in contact with radioactive substances. They are usually short lived radioactive substance.
- High-level waste: High-level wastes are by-product of reaction that takes place inside a nuclear reactor. They occur in two forms: Spent fuel which is accepted for disposal and remaining waste after the reprocessing of fuel. They require 40-50 yrs of time to decay before disposal.
- Transuranic waste: Transuranic waste are man-made radioactive substance such as neptunium, plutonium etc. They are waste produced after reprocessing spent fuel or due to usage of plutonium in nuclear weapons
Harmful effects of radioactive waste:
- The most common disease due to radioactive waste is cancer. Other disease includes anemia, hemorrhages and cardiovascular disease, burns, lesion, nausea and vomiting.
- Soil fertility is lost due to prolonged exposure of radiation .Crops harvested in land affected by radioactive waste are unfit for human and animal consumption.
- There are evidence that radioactive contamination has variety of consequence that alters the cells which lead to irreversible tissue and organ damage
Management of radioactive waste:
Radioactive wastes requires proper treatment, storage and disposal to avoid possible risk factors.
Treatments: Removal of radio nucleotide using filtration, ion exchange or precipitation so that the composition is changed.
Storage: Immobilization of waste in container is done before disposal of waste. For low-level waste the liquid radioactive substance are solidified into cement whereas for high-level waste is calcinated , dried and vitrified in glass matrix. Storing the radioactive waste will help in natural radioactive decay. This is normally done in onsite at power plant or separate field.
Disposal: Deep geological disposal is the best way for final disposal of radioactive waste.
