    Life came to a standstill on April 26, 1986 in Pripyat, when the Chernobyl nuclear power plant explosion took place. The city inhabited by around 50000 people was reduced to dust; many people died in the blast and fire or were exposed to life threatening radiation. The blast took place inside the reactor number four, contaminating tens and thousands of square miles in North Ukraine, Southern Belarus, and Russia in the Bryansk region. It was the worst nuclear accident in history.
    The plight of radioactivity was 400 times more than was released at Hiroshima. It made a third of a million people homeless and activated an outbreak of thyroid cancer among children.
    Today the fierce radioactive remnants of reactor four continuous to smolder beneath the so-called casket of decaying concrete and steel crypt, hastily built after the accident. The casket will soon get a replacement by an arched structure, the size of a stadium that will slide over the reactor and seal it off. With its completion the fourth reactor will be out of sight forever. But for the people living in that area, it will never be out of mind as it’s catastrophe continues to haunt them.
    Apart from the casualties there is the lurking fear of genetic damage for the next so many generations. Biologists are yet to discover the amount of damage on the genetic formations of babies born just after the disaster.
    Chernobyl’s most insidious legacy may be the psychological wounds borne by those who fled from destroyed homes, and by the several million who continue to live on the contaminated land. Many women feel they will give birth to unhealthy babies or babies with no future.
    Olesiya-A specialist in the rescue operations doesn’t know whether to blame Chernobyl for her terrible headache and the fact she says that “sometimes I forget everything” but she has fond memories of growing up in Pripyat built in the 1970 for the Chernobyl’s plant’s personal “it was fantastic”. According to her, Chernobyl was a warm town with lots of trees and rose bushes, she says over a bowl of the cherry dumplings from vareniki in Kiev, about 70 Miles south of Chernobyl, where she lives. We had sports classes. I played handball, swam, played checkers. We even had music lessons on Saturdays. I was in Choir. I enjoyed my childhood. That life ended when Olesiya was only ten years old. At 1:23 A.M. April morning, technicians a botched routine safety test on the reactor number four. The graphite core reactor, a Soviet design, had an inherent instability, and in seconds the nuclear Chain Reaction raised out of control. The Reactor’s cooling water flashed into steam, blasting apart the fuel rods. Western reactors are sealed inside heavy steel and concrete shelves but this one had little to contain the Explosion. It blew up the roof, scattered the guts of the reactor around the building, and ignited a raging fire from what was left of the graphite core.
