Radioactive contamination occurs when radioactive material is deposited on or in an object or a person. Radioactive materials released into the environment can cause air, water, surfaces, soil, plants, buildings, people, or animals to become contaminated.

What is the main cause of radioactive pollution?
However, nuclear power plants are the main sources of radioactive pollution. In addition to the power plants, nuclear weapons factories and wastes of radioactive materials play an important role in radioactive pollution.
What are the sources of nuclear pollution?
Man-made sources of radiation pollution are mining and refining of plutonium and thorium, production and explosion and nuclear weapons, nuclear power plants and fuels and preparation of radioactive isotopes.
What is atomic pollution?
Radioactive contamination, also called radiological contamination, is the deposition of, or presence of radioactive substances on surfaces or within solids, liquids or gases (including the human body), where their presence is unintended or undesirable (from the International Atomic Energy Agency (IAEA) definition).
What causes radiation in the environment?
The majority of background radiation occurs naturally from minerals and a small fraction comes from man-made elements. Naturally occurring radioactive minerals in the ground, soil, and water produce background radiation. The human body even contains some of these naturally-occurring radioactive minerals.
How does nuclear pollution affect the environment?
Nuclear energy produces radioactive waste
A major environmental concern related to nuclear power is the creation of radioactive wastes such as uranium mill tailings, spent (used) reactor fuel, and other radioactive wastes. These materials can remain radioactive and dangerous to human health for thousands of years.
How bad is nuclear waste?
Nuclear waste is hazardous for tens of thousands of years. This clearly is unprecedented and poses a huge threat to our future generations. Many industries produce hazardous and toxic waste. All toxic waste needs to be dealt with safely, not just radioactive waste.
Is nuclear waste green?
Nuclear plants also produce low-level radioactive waste which is safely managed and routinely disposed of at various sites around the country. It is a solid. ... The radioactive byproducts of nuclear reactions remain inside the fuel. No green goo anywhere.
How does Japan dispose of nuclear waste?
Now the big question: where will Japan dispose of its nuclear waste after reactor restart? ... Currently, Japan plans to store nuclear waste at a depository more than 300 meters underground for up to 100,000 years, at which point radiation levels will have fallen low enough to pose no risk to the environment.
Can nuclear waste be reused?
Used nuclear fuel can be recycled to make new fuel and byproducts. More than 90% of its potential energy still remains in the fuel, even after five years of operation in a reactor.
What is the largest source of radiation in the environment?
The biggest source of natural background radiation is airborne radon, a radioactive gas that emanates from the ground. Radon and its isotopes, parent radionuclides, and decay products all contribute to an average inhaled dose of 1.26 mSv/a (millisievert per year).
Where does radiation occur naturally?
Radiation is natural and found everywhere – it comes from outer space, the air we breathe, and the earth we tread. It's even in our bodies; naturally occurring radioactive elements in our bones irradiate us on average 5000 times per second.
