Nuclear Pollution: Definition, Causes, and Effects

What is Nuclear Pollution?

Nuclear pollution, also called Radioactive 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. Pollution of the atmosphere by radiation and radioactive particles is called nuclear pollution.

Such contamination presents a hazard because of the radioactive decay of the contaminants, which produces such harmful effects as ionizing radiation (namely alpha, beta, and gamma rays) and free neutrons.

The degree of hazard is determined by the concentration of the contaminants, the energy of the radiation being emitted, the type of radiation, and the proximity of the contamination to organs of the body. It is important to be clear that the contamination gives rise to the radiation hazard, and the terms “radiation” and “contamination” are not interchangeable.

The sources of radioactive pollution can be classified into two groups: natural and man-made. Following an atmospheric nuclear weapon discharge or a nuclear reactor containment breach, the air, soil, people, plants, and animals in the vicinity will become contaminated by nuclear fuel and fission products.

Nuclear power reactors do not produce direct carbon dioxide emissions. Unlike fossil fuel-fired power plants, nuclear reactors do not produce air pollution or carbon dioxide while operating. However, the processes for mining and refining uranium ore and making reactor fuel all require large amounts of energy.

Nuclear power plants also have large amounts of metal and concrete, which require large amounts of energy to manufacture. If fossil fuels are used for mining and refining uranium ore, or if fossil fuels are used when constructing the nuclear power plant, then the emissions from burning those fuels could be associated with the electricity that nuclear power plants generate.

What is Radioactive Pollution?

Radioactive pollution is defined as the physical pollution of living organisms and their environment as a result of the release of radioactive substances into the environment during nuclear explosions and testing of nuclear weapons, nuclear weapon production and decommissioning, mining of radioactive ores, handling and disposal of radioactive waste, and accidents at nuclear power plants.

MORE: What is Radioactive Waste?

Nuclear tests are carried out to determine the effectiveness, yield, and explosive capability of nuclear weapons. The proportion of radioactive pollution is 15% of the total energy of the explosion.

Radioactive pollution of water, water sources, and air space is the result of radioactive fallout from the cloud of a nuclear explosion. Radionuclides are the main sources of pollution; they emit beta particles and gamma rays, radioactive substances.

Causes of Nuclear Pollution

Most activities involving radioactive substances have the potential to contaminate the environment. Contains

1. Nuclear weapons test

Beginning with the Second World War when the cities of Hiroshima and Nagasaki were defeated by Japan after the use of atomic bombs, countries are in the race to develop their nuclear weapons in the name of defense, but more threat to rival countries is.

They were led by America, Russia, Britain, France, and China. Nowadays n. Korea, Iran, and many developing countries are equipped to make these weapons.

Weapons testing involves explosions called an atmospheric layer called the stratosphere. The debris from the explosion then comes back to Earth as radiation. Some radiation is absorbed by our atmosphere.

But some part of it reaches the falling earth at places that are far away from the place where the weapon was initially released. This is called Fallout. When these particles settle on vegetation and are eaten by animals, they enter the food chain.

When the fallout settles over the sea, the ocean ecosystem is affected and re-enters the food chain.

2. Nuclear Power plants

Rapid nuclear energy from radioactive fuels is used to heat water into steam. Steam is then used to turn on the turbines which in turn act as generators to produce electricity. A small amount of radiation is released into the water during this process, which can then be the cause of nuclear pollution.

3. Improper Disposal of Spent Nuclear fuel.

Spent nuclear fuel consists of very active radioactive atoms that sometimes last for about 600yrs or more. These should be dealt with very carefully, with strict rules in well-specified locations.

But the fact is that many governments approve the dumping of nuclear fuel from their country as much as possible. The popular dumping ground of many countries was the Pacific Ocean.

Greenpeace, an organization dedicated to preserving the environment and protecting the Earth from pollution, has noted this activity and has opposed it enthusiastically.

Some plants spent fuel in underground water pools because they release a high amount of heat and need to be cooled. There is always a danger of contaminating the groundwater and the surrounding land, seeping into the nearby land.

4. Accident/damage to Nuclear Power Plants

This was the most famous Chernobyl nuclear disaster in Russia in 1986. The result of this accident was felt in three countries – Russia, Ukraine, and Belarus. The area around the reactor is still polluted and not suitable for habitat or farming.

On March 11, 2011, the Fukushima Daiichi nuclear accident was another recent accident. The main reactors and supplementary generators were severely damaged due to the tsunami earthquake.

Inadequate preparation to deal with an incident of this scale was also a factor that leads to the hydrogen explosion and the leakage of radioactive material into groundwater.

Effects of Nuclear Pollution

  • The effect of nuclear pollution is seen on every organism in the environment, from bacteria to plants to humans. Nothing spared.
  • Experience radiation sickness, closest to and closest to the source. In small doses of 75–200 reams. One experiences vomiting, fatigue, and loss of appetite. There is a high risk of 300 REM and more changes in blood cells and bleeding. There is the loss of hair above 600 REM, immune loss usually ranges from a few days to weeks. Radiation causes changes in the body’s cell and gene structure, such as the bone marrow, skin, intestine, lymphoid tissue, and fetus.
  • Those exposed from far away may not see any immediate symptoms. But various forms of cancer tend to develop and have a shorter life span. Radiation also causes cell mutations that can be transferred to the next generation.
  • The fetus is affected by birth defects and cancer. Their lifespan may also be shorter.
  • Plants die and show some genetic changes and enhanced growth. Animals are also affected and do not survive very long.
  • Radiation will not dissolve quickly in the atmosphere. Every water source will also be affected. In fact, it may take years or centuries to reach a point where such a place may be habitable.
  • An average person will be exposed to about 180 milliliters of radiation a year through exposure to natural radiation, medical and dental X-rays, color TV, airport baggage X-rays, etc.

Prevention of Nuclear pollution

  • The right safety gear, such as a lead apron, must be worn while undergoing X-rays or radiation therapy procedures. It also includes pregnant women. It is also mandatory to use lead sheathed walls in imaging facilities.
  • As a person, one should be aware of the dangers of nuclear pollution. If living in the vicinity of a nuclear plant or planning someone’s planning, the person’s authority should be exercised to ensure that the governing body for the manufacture, implementation, and disposal of waste is fully planned Have been. Ensure that officers are prepared in the event of a disaster so that they can handle all situations such as arranging evacuation to avoid contamination.
  • Workers are always monitored for the amount of radiation they were exposed to while working at a radiation facility or a nuclear plant.
  • Radioactive waste can actually be recycled to a great extent as useable fuel is still being made into useless materials that can later be reclaimed.
  • Governments are authorizing research on developing better means for the disposal of radioactive waste. The most viable method now appears to be deep underground storage of waste.
  • Power plants must ensure that radioactive fuel and waste are transported and disposed of in safe containers that are long-lasting and unbreakable.
  • Operating agencies need to ensure that radioactive material does not fall into the wrong hands, which they sell for profit to those in the waging war business.


What is Nuclear Pollution?

Nuclear power reactors do not produce direct carbon dioxide emissions. Unlike fossil fuel-fired power plants, nuclear reactors do not produce air pollution or carbon dioxide while operating. However, the processes for mining and refining uranium ore and making reactor fuel all require large amounts of energy.

What causes nuclear pollution?

It happens due to the release of radioactive substances into the environment during nuclear explosions and nuclear weapons testing, production and decommissioning of nuclear weapons, the mining of radioactive minerals, the handling, and disposal of radioactive waste, and accidents at nuclear power plants.

What is nuclear pollution causes and effects?

Development of Diseases due to Radioactive Pollution Exposure. The most common disease that arises in people that have been exposed to radioactive pollution is cancer. Other dangerous diseases that might be brought on by exposure to radioactive waste include anaemia, leukaemia, haemorrhages, and cardiovascular diseases.

What are the effects and prevention of nuclear pollution?

Radiation Pollution can be controlled and prevented at various levels, including the handling and treatment of radiation waste, the control, and mitigation of nuclear accidents, as well as the control and minimization of personal exposure to radiation at an individual level.

How does nuclear pollution affect the environment?

Nuclear power plants use uranium as fuel. The process of mining uranium releases high amounts of carbon dioxide into the environment. Carbon dioxide is also released into the environment when new nuclear power plants are built. Finally, the transport of radioactive waste also causes carbon dioxide emissions.

How does radioactive pollution affect humans?

Exposure to very high levels of radiation, such as being close to an atomic blast, can cause acute health effects such as skin burns and acute radiation syndrome (“radiation sickness”). It can also result in long-term health effects such as cancer and cardiovascular disease.

What are types of radioactive pollution?

Alpha particles, beta particles, neutrons, and protons are particulate radiation. Alpha particles, beta particles, and gamma rays are the most commonly encountered forms of radioactive pollution.

Why is radioactive pollution most harmful?

Nuclear radiation is more dangerous than other forms of pollution because Radioactive pollution affects our environment. The radioactive wastes cannot be destroyed and hence they remain in our environment for a longer period of time. Even disposal of radioactive wastes may cause pollution and damage the environment.

What are the effects of nuclear hazards?

The principal initial effects are blast and radiation. The blast causes damage to lungs, ruptures eardrums, collapse’s structure, and causes immediate death or injury. Thermal Radiation is the heat and light radiation, that a nuclear explosion’s fireball emits producing extensive fires, skin burns, and flash blindness.

How does nuclear waste affect water?

Throughout the nuclear weapons complex, some of the groundwater is polluted, often at levels greatly exceeding safe drinking water limits. Generally, this has not yet affected offsite or public water supplies seriously. But such good fortune may not last, given the quantity and longevity of the wastes.

Which part of human body is first highly affected by nuclear radiation?

Blood cells have the highest turnover rate in our bodies, so the tissue where they have produced the rapidly dividing cells of the bone marrow is the most susceptible to radiation damage.

Which part of the body is most sensitive to radiation?

Lymphocytes (white blood cells) and cells that produce blood are constantly regenerating, and are, therefore, the most sensitive. Reproductive and gastrointestinal cells are not regenerating as quickly and are less sensitive.

How does radiation affect our environment?

UV radiation generates ground-level ozone (O3) and some particulate matter (PM, frequently called aerosol) that include nitrate, sulfate, and organic aerosols causing an adverse effect on human health and the environment. UV promotes the formation of hydroxyl radicals that act as cleaning agents for the troposphere.

How the nuclear radiations affect the environment for long time?

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.

What are the natural sources of radioactive pollution?

The composition of the earth’s crust is a major source of natural radiation. The main contributors are natural deposits of uranium, potassium, and thorium which, in the process of natural decay, release small amounts of ionizing radiation.

What causes radioactive waste in water?

Nuclear power plants placed at the coastal regions add to the radiological contaminants in the marine water by releasing atomic wastes. Water is also used as coolants in these powerhouses, which also get contaminated. Nuclear submarines cause radioactive contamination in the marine environment.

Why is nuclear waste a problem?

Activities that produce or use radioactive material can generate radioactive waste. Radioactive waste is hazardous because it emits radioactive particles, which if not properly managed can be a risk to human health and the environment.

How do we recycle nuclear waste?

For recycling, spent nuclear fuel is fed into a chemical processing system that separates actinide elements that can be recycled as mixed-oxide fuel to produce more electrical power. At PNNL, this research is done in the Radiochemical Processing Laboratory, a Hazard Category II non-reactor nuclear research facility.

Is nuclear waste green?

The radioactive byproducts of nuclear reactions remain inside the fuel. No green go anywhere. There is not that much of it. All of the used fuel ever produced by the commercial nuclear industry since the late 1950s would cover a whole football field to a height of approximately 10 yards.

How does nuclear waste affect animals?

Much like human survivors of the Hiroshima and Nagasaki atomic bombs, birds and mammals at Chernobyl have cataracts in their eyes and smaller brains. These are direct consequences of exposure to ionizing radiation in the air, water, and food.
