Radiographic examination of objects

Principle

An X-ray tube produces X-rays that cause a fluorescent screen to emit light. Objects that are located between the X-ray source and the fluorescent screen will be irradiated so that their inner structure becomes visible. If one varies the anode current and voltage, the change in intensity can be observed in a qualitative manner on the fluorescent screen.

Tasks

1. X-ray an object and observe the result on the fluorescent screen.
2. Vary the anode current and voltage and observe the result on the fluorescent screen.
