Impacts of Radiation

IMPACTS OF RADIATION Ashrafuz Zaman Sk M. Sc, B. Ed, SLE, TET, M. Phil scholar (D. U) -At present environmental degradation is matter of concern and has received the top priority in current topics in political agenda across the globe. Apart from all other biodegradable and non biodegradable factor, todays most emerging threat to the environment is the nuclear radiations and electromagnetic radiations. Nuclear fissions in nuclear activities such as testing of atomic bombs, uses of nuclear weapons in wars, Nuclear accident and Nuclear power plants have created threats and hazards for human being due to its radioactive emissions of energy and harmful high energetic particles. Most of the part of radiated energy is thermal energy which could disturb the heat budget of the environment and can be shown using mathematical model based on relativistic mass energy relation. Calculation reveals the emitted particles and rays are high energetic and ionizing particles such as ray that leads to various biological effects on human body. Moreover, radioactivity is a long term process and radioactive emission continues for years and years and it imposes a big challenge to the disposal of the nuclear wastes. Besides it, thermal radiations from nuclear activity may pollute the aquatic ecosystem. The threat posing to human being due to nuclear activity in future is Nuclear winter which may adversely affect the animal kingdom and human being. Cold Nuclear fusion could be a partial solution to Nuclear fission. In addition to Nuclear hazards, the most recent pollution owing to the call of modernization is the threats from different sources of electromagnetic radiations which too have its adverse effects on our physical and mental health.
