Radioactive Pollution

Presentations | English

The increase in natural radiation levels caused by human activities. 20 percent of the radiation we are now experiencing is mainly due to human intervention. Some causes are mining, handling and processing of radioactive material, storage of radioactive waste, using radioactive reactions to generate nuclear energy and radiation in medicine. Types of pollution include continuous, occasional and accidental. Radioactive materials emit radiation and the harm they can cause depends on the radioactive elements and their half time function. Some are present in the environment and some are used in nuclear power plants. Examples are Caesium-137, Strontium-90, Plutonium-238, Uranium-235, Chromium-51, Cobalt-57 etc. Effect of this pollution can vary with individuals. Exposure to high amount of radiation can generate chronic diseases, cancer or even death. Low amount radiation exposure can cause health problems like neurological, cardiac or reproductive dysfunctions. More information about the topic can be accessed from the presentation.
