Environmental radioactivity is a term that is used to describe the radioactivity that occurs naturally in the environment. It includes radioactive elements such as uranium, thorium and potassium, which are all naturally occurring in rocks, soil, and water. In addition, there are other radioactive particles that are released through natural sources such as volcanoes, geothermal activity and cosmic rays.

Environmental radioactivity can also be caused by human activities. For example, nuclear power plants, nuclear weapons testing, and the production and use of radiation sources like x-ray machines, can all contribute to environmental radioactivity. Nuclear accidents or accidents involving radioactive materials can also release radioactive particles into the environment.

When radioactive particles are released into the environment, they can enter the water, soil, and air, and move through the food chain. This can result in exposure to radiation for humans, animals, and plants. In humans, exposure to radiation can cause health risks from DNA damage and increase the risk of developing cancer.

To reduce the potential for environmental radioactivity, it is important to keep non-natural sources of radioactivity under control. This can be done by properly storing and disposing of radioactive materials, controlling the amount of nuclear power plants, and reducing the amount of nuclear weapons testing. Additionally, it is important to monitor the amount of radioactive elements that are naturally occurring in the environment to ensure that the overall levels do not become too high.
