India's first atomic power station is

  1. BARC

  2. Tarapur atomic power station

  3. Narora atomic power station

  4. none of these
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Tarapur Atomic Power Station (T.A.P.S) was the first nuclear power plant in India. The construction of the plant was started in 1962 and the plant went operation in 1969. It is the world's oldest nuclear power plant in commercial operation. It was build for the departments of Atomic Energy by General Electric and Bechtel.

An atom bomb is based on the principle of

  1. nuclear bomb

  2. nuclear fusion

  3. the liquid drop model

  4. none of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A

Atom bomb is based on the principles of nuclear bomb. When the nuclear bomb detonated gamma rays and X-rays emitted it to thermonuclear temperatures. The ensuing fission reaction creates enormous numbers of high speed neutrons, which can then induce fission in materials not normally prone to it, such as depleted uranium.

Which of the following is followed while handling the radioactive materials?

  1. Wearing protective clothing.

  2. Keeping as far away as is practicable - for example, by using tongskeeping

  3. Keeping radioactive materials in lead-lined containers,

  4. All of the above.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

D

While handling with radioactive materials we must wear protective clothing and keep it as far as possible. The radioactive materials must be in a lead lined contained because the gamma rays emitting from the radioactive material can be prevented using lead lined materials only.
