Radioactive Pollution: Paragraph on Radioactive Pollution!
In spite of certain harmful effects of radioactivity, nuclear power and other uses of radioactive elements have become an integral part of modern development. Many of the environmentally conscious countries in the world depend on nuclear power significantly for their electricity generation.
At present, 17 per cent of the world’s electricity is generated through nuclear sources. Nuclear source is considered clean, compact and concentrated. It is clean because its impact on the environment is minimal compared to other energy generating sources. To make it environmental safer still, there is a need for monitoring and prevention measures.
Monitoring of radiation is very necessary for its control. For this, sampling and its proper analysis are necessary. The samples of air, water and soil need to be collected regularly and their analysis both manual and instrumental are done, not only to know the actual level of radioactive pollution but also for its control.
Prevention and control measures are to be adopted to control radioactive pollutants. All measures should so aim that the level of radioactive pollution should not exceed the maximum permissible limit. The industrial wastes having radioactive elements only should be discharged after proper treatment. The high activity wastes should not be discharged.
Now, a few techniques have been developed through which these wastes can be used, if treated properly. The disposal of the wastes into sea is also not a safe method but if possible, these wastes should be sealed in concrete filled steel drums and discharged into depths of 1,000 fathoms or more.
The emission of radioactive pollutants should be controlled at any cost. In uranium mines, wet drilling can be employed. Closed-cycle systems with gaseous coolants of very high purity may be used in the case of nuclear reactors to prevent extraneous activation products. There is also a need to control radiation hazards for workers and officials working in reactors or other places having danger of radioactivity.
A kit to protect from radiation effects and health care should be provided to all workers. What is more, workers at power stations must be trained in radiation protection and radiation hazard control measures. The UN and other agencies of the world are in favour of total ban on nuclear weapons but very little progress has been made in this field. Let us hope that the time will soon come when our world will be free from the danger of atom bombs and other nuclear weapons.
