  2. Tarapur atomic power station

  3. Narora atomic power station

  4. none of these

Show answer
Correct Option: B
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.

chemistry energy production hazards and safety measures of radiations harmful effects and safety precautions for radiations nuclear physics

  1. 3%

  2. 5%

  3. 10%

  4. 20%

Show answer
Correct Option: A
Explanation:

3%

Nuclear reactor provide 3 per cent of the total electricity generation. Despite its rather meagre contribution, nuclear energy holds sustantive promise from the perspective of meeting India's humbingous energy needs in a secure, sustainable low carbon way.

An atom bomb is based on the principle of

chemistry energy production hazards and safety measures of radiations harmful effects and safety precautions for radiations nuclear physics

  1. nuclear bomb

  2. nuclear fusion

  3. the liquid drop model

  4. none of these

Show answer
Correct Option: A
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.

  4. none of the above

Show answer
Correct Option: C
Explanation:

PPE is personal protective equipment refers to protective clothing, goggles, helmets or other garments required to protect the wearer's body from injury and infection. The purpose of PPE is to reduce employee exposure to hazards.

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

physics energy production hazards and safety measures of radiations harmful effects and safety precautions for radiations nuclear physics

  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.

Show answer
Correct Option: D
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.
