Radioactive waste is a byproduct of radioactive materials from its processing or use that often decays naturally after a period of time. Regardless, they contain unstable components (radioisotopes) that emit ionizing radiation which have enormous harmful aspects for the environment. Radioactive waste represents less than 1% of total toxic waste in countries with nuclear energy, so all toxic waste must be handled safely. Partial beta emitters and gamma ray emitters are the most common radioactive medical waste. in industry, as a source of waste, they usually contain alpha, beta, neutron or gamma emitters. Although most radioactive waste comes from manufacturing sources, it contains a naturally occurring radioactivity called [NORM]. After human processing of these substances or their concentration, it becomes technologically-enhanced natural radioactive materials [TENORM]. Much of this waste consists of alpha partials emitting material from the decay chains of uranium and thorium. Additionally, potassium (the main source of radiation in the human body) and rocks are considered sources of radiation even with their low level of radioactivity. When we talk about the risks of radioactive waste, we must mention that it remains radioactive even after use. And this depends on the type of use and the duration of use of the material. This can clearly lead to a higher risk of tumors, cancer. and any other harmful effects. Pregnant women and babies are two major critical conditions for collecting and interacting with radiation. Chernobyl is a great example of the effects that radioactive waste can have on humans. This mess started in UKRAINE in 1986. The report says the Soviet reactor design coupled with the plant's laborious errors...... middle of article ......f methodologies for assessing long-term safety term of the high-level waste storage system and to increase the reliability of their work and its results. This is done through experience between national experts, exchange of information, development of relevant computer models and databases and ensuring their effectiveness all over the world at the international level. In conclusion, I would like to summarize what I have discussed. In this assignment I talked about particles omitting radiation in general, the risks of radioactive waste and the carbonyl accident as an example by way of introduction. And my body focused on the types of radioactive waste, the agencies and organizations associated with their treatment and I also talked about the disposal of highly radioactive waste as the main point of this mission..
