X-Ray Tube

What are the two main components of an x-ray tube?

• Filament and Rotor

• Cathode and Anode

• Stator and Bearing

• Glass Envelope and Housing

What is the primary function of the cathode in an x-ray tube?

• To produce a thermionic cloud

• To serve as a target for electrons

• To dissipate heat

• To support the x-ray tube

Which material is commonly used for the anode in x-ray tubes?

• Copper

• Aluminum

• Tungsten

• Lead

The purpose of the glass envelope in an x-ray tube is to provide

• radiation and electrical protection.

• electrical and thermal protection.

• electrical, thermal and physical protection.

• electrical, thermal, physical and radiation protection.

The maximum allowable leakage radiation from the x-ray tube is

• 100 mR/hr at 1m

• 50 mR/hr at 1m

• 200 mR/hr at 1m
