According to its statement, IAEA was alerted to the explosion coming from the New Safe Confinement, which protects the remains of reactor four of the former Chernobyl Nuclear Power Plant.
Over the next few weeks, 134 servicemen were hospitalised with acute radiation sickness, and 28 of the firemen and emergency clean-up workers were reported dead in the first three months after the explosion from Acute Radiation Sickness and one of cardiac arrest.
A Russian drone has hit the radiation shelter at the former Chernobyl Nuclear Power Plant in Kyiv overnight, Ukrainian president Volodymyr Zelensky has said.
Pripyat’s population of roughly 50,000 was fully evacuated 36 hours after the accident though, in this time, the town went about their day as normal and it wasn't until people started falling ill hours later, complaining of headaches, vomiting and metallic tastes in their mouths, that evacuation began at 2pm.
The reactor overheated and, in combination with its design flaws, generated an explosion comparable with a nuclear bomb but releasing radiation the equivalent of 500 bombs.
