False
In the US, the largest source of man-made radiation comes from nuclear power plants.
False
Nuclear plants are the only electric power plants that create serious hazards to public health and the environment.
False
Nuclear power plants are less expensive to build than are coal-fired plants.
False
Nuclear reactors were originally designed to generate electricity

True
The human body naturally contains a small amount of radioactive material.
True
The major difference between a nuclear power plant and a coal-fired power plant is the fuel used to boil the water.
True
What is nuclear waste?
