D Correct answer
Explanation

Nuclear radiations are extremely harmful to human health. They can cause:

1. The radiations can affect body cells and this may cause cancer.
2. The radiations have the capability to damage the genes of a person and this can be transferred to the next generation.
3. The radiations can cause permanent incurable deformity in human body.

A Correct answer
Explanation

A self sustaining reaction where the neutrons bombard an atom resulting in the fission process which leads to the release of more neutrons which then bombards more atoms and the cycles goes on.

A Correct answer
Explanation

Energy generation from the nuclear energy is greater than from any non-conventional sources of energy. But it has some disadvantages too, such as:

1. Cost of nuclear power plant set up is very high.
2. Waste generated are hazardous to health and environment.

State whether the given statement is True or False :
Waste products emitted from nuclear power plants are very harmful.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Waste products formed during nuclear reactions are highly radioactive in nature and cannot be disposed into the environment directly. Wastes needs to be processed before releasing it into the environment.
