How many deaths and casualties happen at chernobyl?

The Chernobyl disaster, which occurred in April 1986, resulted in immediate deaths of two plant workers on the night of the explosion, with 28 emergency responders dying from acute radiation syndrome in the following weeks. The long-term health effects, including cancer and other illnesses, have led to estimates of thousands of additional deaths over the years, with some studies suggesting that up to 4,000 people could ultimately die from radiation exposure among the higher-exposed groups, while other estimates range much higher. Overall, the total number of casualties and health impacts remain subjects of ongoing research and debate.
