Principle

When a blood vessel model is irradiated with X-rays, the blood
vessels themselves are not visible at first. It is only after the
injection of a contrast medium that the blood vessels become
visible.

Tasks


Inject a 50% potassium iodide solution into the blood vessel
model.

Observe the fluorescent screen of the X-ray basic unit to
follow the course taken by the injected solution in the blood
vessel model.
