Developing new forms of industry and energy, humanity has faced a problem, which an ordinary man rarely thinks about. We are talking about nuclear waste. Scientists are trying as much as possible to neutralize the effect of these substances on the overall environmental picture, producing postulates and storage devices for hazardous waste. However, the trend of accumulation of contaminated material worries people who think about the future of our planet. This issue concerns everyone.
Nuclear wastes include substances that may not be subject to any further use. This is a final product containing radioactive isotopes of chemical elements. Such substances don’t have any practical value and carry only the threat of pollution and exposure. Unfortunately, there are many sources of these harmful substances. There are systems of classification of radioactive waste, which establish the degree of danger.
There are several major suppliers of dangerous radioactive waste. Uranium industry occupies a firm place. Preparation of nuclear fuel contains several stages: uranium mining, processing, and refining. There are possible emergency situations on all these staged that can contribute to environmental pollution. Nuclear reactors and radiochemical industry are also the sources of radioactive contamination. Radioisotope laboratories, which are based in many countries, also ‘contribute’ the environmental pollution.
There are a number of substances that have a natural radioactivity. They include rubidium-87, potassium-40, uranium-238, and thorium-232. Dangerous Decomposition products thereof are also dangerous.
Oil and gas industry are often faced with the content of radium and radon in their deposits. The activity of these industries influences radioactive waste.
Nuclear waste may appear in all forms: gaseous, liquid or solid. It depends on the source and the process of forming the hazardous waste. Some of the allowable concentrations are discharged into waste water, but still there is an accumulation and penetration of it into the atmosphere.
Before, mankind lightly reacted to these harmful substances. It was believed that a dispersion of isotopes in the environment is quite sufficient measures to get rid of unnecessary waste. A little later, it was realized that such treatment of the contaminated substance very quickly responds to future generations. Fast susceptibility of infectious areas has led to a radical change in the disposal process. A number of principles have been developed, which had to limit the impact of nuclear waste.
