(b) - To direct x-rays out of the tube through the window on the shield.
(c) - Tungsten or molybodenum.
- High melting point thus it can withstand high temperature.
(d) (i) Heater current (Filament current)
(ii) Anode potential (operating potential)
(iii) - Covering with protective materials where x-rays are not required
- Minimize exposure time as much as possible
- Reduce number of exposure as much as possible
