Answer:
The correct answer is option 3, that is, exposure of workers to radiation.
Explanation:
The process of nuclear fission takes place when uranium nuclei get bombarded with neutrons. This association dissociates the uranium nuclei apart, discharging radiation, heat, and more neutrons. The neutrons, which gets discharged results in a chain reaction as more uranium nuclei get bombarded, generating huge amounts of energy.
The massive concern related to a nuclear power accident is the negative influences of radiation on the human body. If an individual gets exposed to an acute dose of greater levels of radiation, the outcome would be radiation sickness. Radiation sickness is illustrated as illness resulting due to exposure to a large dose of radiation over a brief time duration. The signs may comprise nausea, skin burns, diarrhea, vomiting, general weakness, hair loss, and possibly death.
