Geiger tube

8.0
A small tube inside a Geiger counter that gives a signal when radiation passes through
  • noun
  • /ˈɡaɪɡər tuːb/
  • Specialized
translation icon : tubo Geiger
  • Radiation is detected when ionizing particles pass through the Geiger tube and create an electrical pulse.

Examples

  • The Geiger tube inside the counter must be replaced periodically for accurate radiation measurement.

  • Older models used a fragile Geiger tube that was easily damaged during fieldwork.

  • The Geiger tube detects radiation levels.

Morphology

Geiger + tube

This is an eponymous technical term: 'tube' transparently signals a hollow cylindrical object, but 'Geiger' is a proper name with no lexical meaning for most learners and the specific function (an ionization chamber in a radiation detector) is highly specialized. A B1 learner who knows the constituents might guess it is some kind of tube associated with a Geiger device, but would not be able to derive its detector/chamber role without prior exposure, so the expression is only partially transparent.

Etymology

Geiger tube is named after the scientist Hans Geiger and refers to the small tube inside a Geiger counter. When invisible 'radiation' passes through, the tube makes a tiny electric 'click' or pulse, so the Geiger tube is the part that 'detects' radiation.
