1. HUMAN IMPACTS? The immediate effect of disaster caused the death of two workers followed with several deaths within few hours of the explosion. The death rate was continuously increased with several radiation sicknesses.? Due to faulty nuclear reactor radioactive materials iodine-131, cesium-134 and cesium 137 were released . According to UNSCEAR, among these radioactive materials, iodine-131 has less duration of action due to its short half life, nearly 8 days.
But this is easy to reach in thyroid gland via air. Cesium molecules have longer duration of action as they are having prolonged half life. The scientists were worried about their long term effects.? The residents of Pripyat, were released from that area almost after 36 hours of incidence. Within this period, different health effects were noticed such as headaches, nausea, vomiting and miscellaneous radiation health effects. Surrounding 30km area almost vacant, people left their personal everything behind.
? According to U.S. NRC, within 3 months of nuclear accident, 31 people died due to radiation effect? The number is exceeding 6,000 of thyroid cancer cases which were relating the effect of radiation exposure. The effect of radiation exposure is continuous, though it is mild and considered 0.1 REM per year. In this contaminated area almost five million residents are living and get affected with solid tumor, leukemia. The exact relation to the radiation induced health effect and the number of sufferers, is not yet clear.
? Some fear effects still present in the surrounding areas, Many doctors from Eastern Europe and Soviet Union still suggested for abortion to pregnant women, as radiation poisoning causes birth defects or other disorder to fetus.2. ENVIRONMENTAL IMPACTS? After a short interval of the accident the woodland present nearby area of the Chernobyl, is affected by radiation exposure and killed several plants . The area is now known as ‘Red Forest’, as the colour of the trees turned to ginger color due to burning. The wild lives stayed in the forest were no more exist.
? The large area, including Pripyat and Chernobyl is considered as “zone of alienation” and limit the humans living. The nuclear plant management team is working hard to stop the leakage of the radioactive materials from the reactor, and able to completely shut down its last reactor in December 2000.? Some of the former residents were coming back to stay in their houses and government officials and researchers are allowed to inspect the sites. In 2011, Ukarine opened the area for visitors to see the disastrous effect of the radiation.? This allowance does not provide any indication that the area is totally safe for living.
The long effect of the radiation is continuing.
