Radiation detector or the like

Abstract

The measuring probe at the top end of a telescopic tube of a radiation counter for measuring an ionizing radiation is connected to the measuring circuit via a thin ribbon cable capable of being wound onto a take-up drum of a metering instrument. A thin steel tape is attached to the ribbon cable and extends in parallel therewith. When a mutual twisting of the individual sections of the telescopic tube occurs while the same is being extracted, the ribbon cable is prevented from being twisted as well, because the measuring probe is axially rotatable and runs in ball bearings, and because the thin attached steel tape has the necessary torsional rigidity. Together with the steel tape, the ribbon cable can be wound onto the take-up drum even at very low temperatures (such as -30.degree. C.) without any noteworthy additional winding force being required to this end.
