Radioactive pollution occurs when radioactive materials are present or deposited in the atmosphere or environment, especially when their presence is unintentional and poses a risk to the environment due to radioactive decay. Radioactive pollution has a wide range of severe consequences for humans and the environment. The consequences of radioactive pollution can differ greatly among individuals depending on the amount of radiation exposure and the sensitivity of the exposed person. High levels of radiation can induce chronic disorders, cancer, gene mutation, cell disintegration, or even rapid death in rare circumstances of extreme exposure. This article will explain to you about Effects of Radioactive Pollution which will be helpful in preparing the Environment Syllabus for the UPSC Civil Service exam.

Radioactive Pollution - Concept

• The rise in natural radiation levels induced by human activity is referred to as radioactive pollution.
• The radioactive materials cause destruction by emitting hazardous ionizing radiation (radioactive decay) such as beta or alpha particles, gamma rays, or neurons into the environment where they exist.
• Human activities are considered to be responsible for around 20% of the radiation we are exposed to.
• Activities involving radioactive materials, such as mining, handling and processing radioactive materials, handling and storage of radioactive waste, and the use of radioactive reactions to generate energy (nuclear power plants), as well as the use of radiation in medicine (e.g. X-rays) and research, are all examples of human activities that can release radiation.

Effects of Radioactive Pollution

Genetic Mutations

• When it comes to genes and genetics, radiation has negative consequences.
• It causes DNA strand damage, which leads to genetic disintegration over time.
• The degree of genetic mutation leading to changes in DNA composition varies depending on the amount and type of radiation one has been exposed to.
• If a person or animal is exposed to too much radiation through the atmosphere, food, or even water, their bodies are likely to have already absorbed the radiation.
• Because energy cannot be eliminated, it remains active once within the body.
• As a result of the mutation, one is extremely vulnerable to cancer.
• Children born to pregnant women suffer birth abnormalities caused by genetic mutations, such as low weight during birth.
• Severely deformed births and impairments in children, such as blindness, have also been observed.
• Radiation-induced infertility has also been reported as a side effect.

Diseases

• Our health is severely harmed by radioactive pollution. Acute radiation syndrome is a rare condition that is one of the most deadly side effects of radioactive pollution.
• It is, however, a result of high-level radioactive radiation. Within a few hours, this condition causes nausea and vomiting.
• If the situation is extremely bad, the person may die in a matter of days or weeks.
• Radiation can also cause cancer, which is by far the most common side effect.
• However, while cancer is the most common side effect of radioactive pollution, it can also induce other disorders.
• Anemia, decreased life expectancy, leukemia, bleeding, accelerated aging, fatalities, cardiovascular issues, and so forth.

Soil Infertility

• Radiation is prevalent in soils due to its exposure to the atmosphere.
• Radioactive compounds in the soil react with various nutrients, causing the nutrients to be destroyed and the soil to become infertile and very poisonous.
• Such soil results in the harvest of crops that are contaminated with radiation and consequently unsafe for human and animal consumption.
• Plants that grow in this type of soil are genetically modified as well.
• Herbivores eat them and retain the radiation levels because they are at the bottom of the food chain.
• Carnivores such as lions and vultures consume them, boosting their radiation levels by the principle of Biomagnification.

Cell Death

• Radioactive pollution has a variety of impacts, including cell mutation and cell death.
• The bodies of living beings are one-of-a-kind because they include millions of cells, each with its particular function to complete.
• Radiation causes the cells in the body to become distorted, resulting in irreversible damage to the organs and organ systems.
• Permanent sickness and death are unavoidable in the face of excessive radiation.

Burns

• Radiation is harder to identify, but it is easy to recognize when a person has been exposed to it.
• The existence of burns, red blisters, and sores in the immediate vicinity is proof.
• To make matters worse, it's possible that this will result in skin cancer.

Impact on Wildlife

• The animals suffer in different ways depending on their level of suffering.
• Insects and flies are less affected than higher-level species.
• When herbivores, such as cattle, graze on contaminated terrain, the deposited Ce-13 and I-131 accumulate in considerable amounts on the animal tissues.
• These radionuclides interact with their DNA and enter their metabolic cycles (mentioned above; ionizing).
• Due to a minor number of radionuclides, this results in a mutant animal generation with a higher risk of health complications.

Impact on Plants

• Plants are likewise subjected to radiation, with increased Ultraviolet waves causing the majority of the damage.
• Different plants are impacted in different ways.
• As the number of radiation increases, the stomata stop evaporating. When chromosomes are damaged by radiation, reproduction is impeded.
• Plants' forms, sizes, and health are all affected.
• When plants are exposed to excessive levels of radiation, they die. We consume nuclides when we eat these plants.

Impact on Birds

• In comparison to the human body, a bird's surface area is larger than its body weight, hence it absorbs more radiation.
• Furthermore, because the bird's body contains less fluid due to its small size, it heats up quickly.
• Birds' navigation skills are disrupted by the magnetic field from the towers, so when they are exposed to EMR, they become disoriented and fly in all directions.
• Collisions with telecommunication poles kill a considerable number of birds each year.

Impact on Marine Life

• For decades, power plants have been releasing radioisotopes into the water as a source of nuclear energy and chemical processing.
• They include Cesium, Radon, Crypton, Ruthenium, Zinc, and Copper, to name a few.
• The fact that the waste is emitted at a "permissible" level does not imply that it is safe.
• These radionuclides can be found in the fishes' soft tissues as well as their bones.
• The radioisotope of ruthenium was believed to be present in the seaweed used in bread.
• The shells and tissues of all shelled fishes are polluted with radionuclides.

Measures to Control Radioactive Pollution

Proper Method of Disposing of Radioactive Waste

• Radiation can still be found in radioactive waste. As a result, it cannot be disposed of in the same manner as for regular waste.
• It cannot be buried or incinerated. Because seepage is a possibility, this waste should be stored in large, thick concrete containers.
• Since storage may not be practicable, another alternative is to dilute the radiation.
• Professional assistance should always be sought because there are no straightforward ways to dispose of radioactive waste.

Proper Labeling

• Any material containing radioactive material must be labeled, with the required precautions stated on the label's content.
• The reason for this is that even light contact with radioactive material can allow radiation to enter the body.
• Containers containing such materials should be clearly labeled to encourage the use of protective equipment when handling them.

Prohibition of Nuclear Tests

• It has already been established that nuclear power possesses a great deal of latent destructive force.
• Nonetheless, the tests conducted to perfect the energy play a significant role in the overall presence of radioactive materials.
• Furthermore, although being conducted in the deserts, these tests wind up leaking into other ecosystems, impacting the livelihoods of many people.

Alternative Energy Sources

• Initially, the development and usage of nuclear power was not a dreadful thing.
• However, given the harm and threats it poses to the environment, it is past time for its use to be phased out in favor of alternative and ecologically friendly energy sources, such as renewable energy sources such as solar, hydroelectric, and wind power.
• When radioactivity is used to generate energy in nuclear power plants, for example, the waste emitted from the various processes and combustion results in more radiation being discharged into the atmosphere.

Conclusion

Radiation pollution is the most damaging and serious of the various types of pollutants that make up environmental pollution. The destructive consequences of radiation pollution on humans have also been documented by historical evidence. It also has an impact on the masses' human rights, for which the state is ultimately responsible. Although there are some legal mechanisms, there are no special laws in place to protect and promote human rights from radiation pollution in accordance with international human rights principles. There is currently no human rights-oriented policy framework in place to protect and promote the human rights of those who are affected by radiation pollution. As a result, proper measures must be designed to eliminate pollution and protect human rights.
