Which statement about the waste materials from nuclear power plants is true?
the waste gives off bursts of radiation over a short time.
the waste produces small amounts of greenhouse gases for a long time.
the waste emits harmful radiation for a long time.
the waste generates a large amount of carbon dioxide over a short time.

The correct answer is "The waste emits harmful radiation for a long time".

Explanation:

Nuclear fission: The nuclear energy is generated from the splitting of uranium atom. Here, Uranium is a radioactive material.

Nuclear reactor controls the release of energy.

The by product of the nuclear generation is the radioactive waste in the nuclear power plant. The radioactive material emits harmful radiation. Some industries throw their radioactive waste material in river. It would be harmful for marine life.

The radioactive material emits harmful radiation. If there is any leakage in the power plant. It could cause cancer, skin burn and birth defect to the employees who are working in the nuclear power plant.

Therefore, the true statement is "The waste emits harmful radiation for a long time".
