mechanisms and other plant equipment. The incident began at 1:23 a.m. on April 26, when hot nuclear fuel rods were lowered into cooling water, releasing an immense amount of steam and creating more reactivity because of the RBMK reactor's design flaws. This started a series of explosions and fires that damaged reactors number three and four. Less «

More than 6,000 cases of thyroid cancer may eventually be linked to radiation exposure, but the precise number of illnesses related to the Chernobyl accident is difficult, if not impossible, to ascertain.

continuted in operation for several years, and was finally shut down entirely in December 2000. The plant, the ghost towns of Pripyat and Chornobyl, and a large area surronding the plant now known as the "zone of alientation" are largely off-limits to humans. Less «
Because of the long-lived radiation in the region surrounding the former Chernobyl Nuclear Power Plant, the area won't be safe for human habitation for at least 20,000 years.
