Característica de un tubo contador

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 ...

Examinación radiográfica de diferentes objetos

Principio

Un tubo de rayos X produce radiación X que provoca brillos en una pantalla fluorescente. Los objetos que se encuentran entre la fuente de rayos X y la pantalla se irradian y su estructura interna se hace visible. Si se varia la corriente y el voltaje del ánado se puede ...

Estudio cualitativo de absorción de rayos X

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 ...

Ionización por rayos X

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 ...

Monocromatización de rayos X de molibdeno

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 ...
