CORRECT!!!
1. Which of the following reduces leakage radiation to required standards?
Answer: ✔✔ Protective housing
Explanation:
The protective housing of the x-ray tube is designed to contain the x-rays
and reduce leakage radiation. It is made of a lead-lined material to absorb
any radiation that escapes from the tube and prevent it from exposing the
surroundings. The housing is also designed to keep the tube cool and prevent
electrical shock to the operator.
2. Which component of the x-ray tube is responsible for concentrating the
electron cloud?
Answer: ✔✔ Focusing cup
Explanation:
The focusing cup is part of the cathode assembly of the x-ray tube. It is a
negatively charged metal cup that surrounds the filament and helps to
concentrate the electron cloud as the electrons are accelerated towards the
anode. This focused beam of electrons allows for better spatial resolution
and more efficient production of x-rays.
3. The x-ray tube is a part of the:
Answer: ✔✔ X-ray circuit secondary
Explanation:
The x-ray tube is part of the secondary circuit in the x-ray system. The
secondary circuit is where the high-voltage energy, generated by the
transformer, is applied to the x-ray tube to create x-rays. The primary
circuit involves components like the generator and step-up transformer,
