Counter tube characteristics

Principle

The counter tube uses the ionising effect of high-energy radiation in order to measure the intensity of the radiation. The counter tube characteristics describe its working range, i.e. the voltage range in which it reliably counts the incoming particles.

Tasks

Determine ...

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 ...

Qualitative examination of the absorption of X-rays

Principle

X-rays penetrate objects that are impenetrable for visible light. The absorption depends on the thickness and type of the material. This dependence is demonstrated in a qualitative manner on a fluorescent screen with the aid of various different absorption ...

Ionizing effect of X-radiation

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

  1. Illustrate the ...

Monochromatisation of molybdenum X-rays

Principle

The X-rays that are generated by an X-ray tube are polychromatic. Numerous experiments (e.g. Debye-Scherrer experiments concerning crystal structures), however, require monochromatic X-radiation, which can be generated by filtering the X-rays with monocrystals or with the aid of ...
