NEW 2007 PANCAKE GEIGER MUELLER TUBE RADIATION Counter with mica window with diameter 65 mm
This pancake geiger tube has been made in 2007. It is brand new in box.
The counter is designed to be operated in various dosimetric and radiometric devices.
Besides beta-particles, the counter can register alpha-particles and gamma radiation. To register alpha-and beta-particles the counter is provided with a thin mica window.
The other design peculiarity is a minimal possible cathode surface (in comparison with cylindrical end-window beta-counters) that allows registering alpha-and beta-radiation.
The counter is produced in a baseless modification.
