Why do nuclear accidents happen?
A core meltdown accident occurs when the heat generated by a nuclear reactor exceeds the heat removed by the cooling systems to the point where at least one nuclear fuel element exceeds its melting point. Alternatively, an external fire may endanger the core, leading to a meltdown.
Why is nuclear disaster so harmful?
The energy released in the form of particles from the radioactive elements such as uranium, plutonium, etc. is called radioactivity. It spreads in the area and causes nausea, dizziness, vomiting and disorientation. It is very harmful to human health and causes serious illnesses like cancer.

What causes nuclear accidents?
Human exposure to I-131 released from nuclear power plant accidents comes mainly from consuming contaminated water, milk, or foods. People may also be exposed by breathing dust particles in the air that are contaminated with I-131. Inside the body, I-131 accumulates in the thyroid gland, which is an organ in the neck.
