Final answer:
The corrected sentence should include a comma after the year, reading: 'A nuclear power station exploded in Chernobyl, Ukraine, on April 26, 1986.' The Chernobyl disaster is the worst nuclear power plant accident in history, with significant long-term health and environmental impacts.
Step-by-step explanation:
The sentence should be corrected by adding a comma after the year to separate the day of the month from the year, resulting in the following: A nuclear power station exploded in Chernobyl, Ukraine, on April 26, 1986. Chernobyl Nuclear Power Plant Disaster: The Chernobyl disaster was a catastrophic nuclear accident that occurred on April 26, 1986, at the Chernobyl Nuclear Power Plant in Ukraine, then part of the Soviet Union.
A dangerous experiment led to an explosion and release of massive amounts of radioactive material. The lack of a containment building, combined with the graphite moderator of the core igniting, resulted in the worst nuclear power plant accident in history.
Acute radiation sickness affected over 200 plant workers and firefighters, with 32 deaths following shortly after the incident. Long-term projections estimate thousands of additional cancer cases due to the released radiation. Today, the destroyed reactor is enclosed in a steel and concrete sarcophagus, and the area remains largely uninhabitable due to ongoing radiation concerns.
