Environmental Impact Assessment (EIA) :
The Environmental Impact Assessment commenced in 1960s. The main aim of EIA is to conserve environment. EIA assess the anticipated environmental effects of a proposed project. They also act as tool for environmental management forming a part of project approval and decision making
Objectives of Environmental Impact Assessment:
Different stages involved in EIA process:
- Screening: Need of full or partial study of the project is decided in this process. The project is screened for location, investment and type of development.
- Scoping: EIA boundaries are established. The basic data to be analyzed for the project is decided. The potential impacts of the project are monitored. Scoping is used to identify alternative solution to avoid, mitigate adverse impact on environment
- Assessment and development of alternative: Analyze the environmental impact of the proposed project and provide detailed information on alternatives.
- Reporting to EIA: Submitting the EIA report, including environmental management plan and detailed non- technical summary for general audience.
- Decision making: On whether to approve or reject the project by providing proper reason
- Monitoring and auditing: Ensuring the priorities and mitigation measures mentioned in EMP are properly implemented and monitor whether the potential impact are effectively addressed.

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 ofRead more
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:
Harmful effects of radioactive waste:
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.

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
