Geiger tube
- noun
- /ˈɡaɪɡər tuːb/
- Specialized
- 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.
