Radioactive Pollution: Its Impact On Human Health

Radioactive pollution, also known as radiological pollution, is the presence of radioactive substances in solids, liquids, gases, or on surfaces, including the human body. It is estimated that about 20% of the radiation we are exposed to is due to human activities such as mining, handling, and processing radioactive materials, and the use of nuclear power plants. Radioactive pollution can have a wide range of negative effects on human health, including genetic mutations, cell damage, and an increased risk of developing serious diseases. The impact of radioactive pollution on human health depends on factors such as the amount of radiation exposure, the sensitivity of the exposed person, and the duration of exposure. Understanding the effects of radioactive pollution on humans is crucial to mitigate its potential harmful consequences and ensure the safe handling and disposal of radioactive materials.

Radioactive pollution can cause genetic mutations and cancer

The human body is composed of millions of cells, each with a specific function. Radioactive pollution distorts these cells, resulting in irreversible destruction to various tissues and organs. The extent of genetic mutation depends on the amount and type of radiation exposure, and it can lead to changes in DNA composition. If a person is exposed to a large amount of atmospheric radiation, their body will absorb it, leading to a higher risk of developing cancer.

The most common disease that arises from exposure to radioactive pollution is cancer. Other dangerous diseases that may be brought on by exposure to radioactive waste include anaemia, leukaemia, haemorrhages, and cardiovascular diseases. Exposure to very high levels of radiation can cause acute health effects such as skin burns, nausea, vomiting, and acute radiation syndrome ("radiation sickness"). It can also result in long-term health effects, increasing the risk of cancer over a lifetime.

Radioactive pollution can enter the body through ingestion, inhalation, absorption, or injection, leading to internal contamination. It can also enter the body through external contamination, where the radioactive material is on the skin, hair, or clothing. In both cases, the radiation stays active inside the body and can make its way up the food chain, affecting both humans and other organisms.

Radioactive pollution can be ingested or inhaled

Radioactive pollution can cause internal irradiation, where it is ingested or inhaled and enters the body. It can also be absorbed through the skin or enter the body through an open wound. The biological effects of ingested radioactive materials depend on the activity, the biodistribution, and the removal rates of the material. Radioactive iodine, for example, will concentrate in the thyroid gland and increase the risk of thyroid cancer, especially in younger people.

The risk of developing adverse health effects from radioactive pollution depends on the radiation dose. Higher doses of radiation carry a higher risk of adverse effects, while lower doses delivered over a longer period carry a substantially lower risk. This is because the body can repair damage caused by low doses of radiation. However, any amount of radiation may cause cancer, and any exposure may cause some health risks, so it is always safer to minimise exposure.

Radioactive pollution can also cause external irradiation, where the source of radiation is outside the body. Penetrating radiation such as gamma rays, X-rays, neutrons, or beta particles pose the greatest risk from an external source. The level of health risk depends on the duration and type of irradiation, as well as the strength.

Radioactive pollution can cause acute radiation syndrome

The symptoms of ARS can start within an hour of exposure and can last for several months. The early symptoms of ARS include nausea, vomiting, loss of appetite, headaches, fatigue, fever, and skin reddening. These symptoms may be followed by a period of apparent improvement, after which additional symptoms develop, leading either to recovery or death. The severity of ARS depends on the radiation dose received, with doses above 8 Gy being almost always lethal, even with medical care.

ARS is typically divided into three types: bone marrow syndrome, gastrointestinal syndrome, and neurovascular syndrome. Bone marrow syndrome occurs at doses of 0.7 to 10 Gy, while neurovascular syndrome occurs at doses exceeding 50 Gy. The cells most affected by ARS are those that are rapidly dividing, and high doses of radiation can cause irreparable DNA damage. Repeated complete blood counts (CBCs) can indicate the severity of exposure, and treatment of ARS typically involves supportive care, including blood transfusions, antibiotics, colony-stimulating factors, or stem cell transplants.

In addition to the immediate health effects of ARS, exposure to high levels of radiation can also result in long-term health consequences, such as cancer and cardiovascular disease. Radioactive pollution can also cause genetic mutations by damaging DNA strands, increasing the risk of cancer and other diseases. It is important to properly dispose of radioactive waste to minimize the impact on human health and the environment.

Radioactive pollution can cause cardiovascular disease

Ionizing radiation from radioactive pollution can damage the DNA in living cells, leading to genetic mutations and an increased risk of cancer. This damage can also contribute to cardiovascular disease by causing micro-vascular injury, inflammation, and oxidative stress. The risk of developing cardiovascular disease increases with the dose of radiation exposure, and it can take many years for the disease to manifest.

Radiation exposure from medical imaging procedures, such as CT scans, has also been linked to an increased risk of cardiovascular disease. Additionally, radiation therapy used to treat benign and malignant diseases has been associated with the development of cardiovascular disease. For example, radiation therapy for peptic ulcer disease has been correlated with increased mortality from coronary heart disease.

Furthermore, radiation exposure during space exploration, radiological terrorism, or nuclear power plant accidents can also increase the risk of cardiovascular disease. The extent of injury to vital organs like the heart following such events is not yet fully understood, and more research is needed to develop treatment strategies.

Radioactive pollution can cause infertility

In men, exposure to radioactive pollution can lead to a decrease in sperm count, motility, and viability. It can also cause oxidative stress, which can result in increased levels of reactive oxygen species, leading to infertility. Studies have shown that exposure to radiation from sources such as cell phones, laptops, and microwave ovens can negatively affect male fertility. The intense exposure to radiation can also lead to testicular cancer, which can further impact fertility.

In women, exposure to radioactive pollution during pregnancy has been linked to an increased risk of adverse reproductive outcomes, including miscarriages, low birth weight, and birth defects.

The effects of radioactive pollution on fertility are a serious concern, and it is important to properly dispose of and protect oneself from radioactive waste.
