Facts, Timeline, and Aftermath of the 1986 Chernobyl Nuclear Disaster

An abandoned city, rusting buildings, rise in cancer and thyroid cases, deformed children and animals... we all know about the Chernobyl Nuclear Disaster that took place in Ukraine more than 25 years ago. Read this Buzzle article, which presents to you some of the most striking Chernobyl Nuclear Disaster facts, along with the timeline of its events, causes, casualties, summary, and long-term effects.

Short and Long-term Effects
Health Effects on Humans
Apart from the death toll of 32 people, which resulted from acute radiation syndrome, at least 30 more died from prolonged radiation sickness (ARS) till 2008. Several children lost their lives due to thyroid problems, and more than 130 cases of confirmed ARS have been recorded. It has been estimated that there might be at least 16,000 cases of thyroid cancer in the surrounding regions till the year 2065, due to radiation exposure from this disaster. Also, till the same year there might be at least 25,000 cases of other cancer types among people who lived in the Chernobyl-Pripyat region. According to estimates, about 180 metric tons of nuclear material in the form of dioxides and fuel products was present in reactor no. 4, and at least 30% of the entire amount got released into the atmosphere. After the explosion, the city of Pripyat was not evacuated immediately, but consequently several people started to fall sick and at least 200 people (mostly from the rescue and relief crew) had to be admitted in hospitals immediately. At least a million people were evacuated from the surrounding regions including Pripyat. The government predicted that in the next few years, cancer rate would rise by at least 2%. On of the worst and most horrifying health effects caused were the mutations; many children had deformed body parts, missing fingers and eyes, missing limbs, deformed skulls, etc. Several cases of dipygus (multiple limbs) were seen in both humans and animals. Apart from thyroid-related diseases, the Down's Syndrome also affected children after the radioactive fallout.
Effects on Plants and Animals
In addition to the Red Forest mentioned above, several patches of land became barren shortly after the incident as floral species absorbed the radiation particles. Several animals who were present in that area died and few experienced a halt in the reproduction process. Some animals suffered from thyroid problems and showed stunted growth. On the reactor walls and outer portions, a type of radiotrophic fungi started growing; they absorb the nuclear energy for their growth. Such fungi were collected by a robot, which was directed into the reactor for further analysis after the disaster. In Germany, it was discovered that the radioactive content in hunted wild boars had increased, and hence it was banned to kill any wild animal for meat in this country. In Norway, the cattle and other livestock had to be given clean and decontaminated food for several months before they and their future generations could be used as meat. Cesium isotopes had the largest impact on the food chain in the United Kingdom region mainly regarding animal husbandry of sheep and their usage for wool and meat. Most of the restrictions were lifted in the last decade. Mutations in animals consisted of reduced brain size, albinism, uneven pair of body parts like limbs, eyes, deformed toes and fingers, etc.
Aftermath
After the incident, considering the aftermath, several concerns were raised about the safety and operations of nuclear power stations all over the world. The development of such stations decreased drastically in the Soviet Government. After many protests by anti-nuclear agencies, several precautions were undertaken at numerous nuclear stations and the secretive transparency of techniques used was reduced to avoid such incidents in the future. A New Containment Structure (NSC) is currently being constructed, which will cover up the entire nuclear reactor no. 4, including the sarcophagus built by the liquidators after the accident took place. This sarcophagus consisted of reinforced steel and concrete, and the purpose was to decrease the amount of radiation spreading out from the reactor's core chambers. The NSC is being designed to completely stop any radioactive particles from being emitted, so that the interior parts would be preserved.
