Principle

As well as the outgoing radiation from a radioactive emitter is
able to ionize air, so also X-radiation shows an ionizing effect.
When air is penetrated by X-radiation, it is electrically
conductive. This is tested on a charged electroscope.

Tasks


Illustrate the ionizing effect of X-radiation with the aid of
an electroscope.

Examine the influence of the anode voltage and amperage on the
duration until the electroscope is discharged.


What you can learn about
