J304βγ Geiger-Müller Counter Tube
Compteur Geiger-Müller sensible aux rayonnements Bêta et Gamma
Beta-Gamma-Zählrohr

The J304βγ China-made glass modern GM tube is very sensitive to both Gamma and Beta radiation. It has a screw-type base for easy mounting in a Geiger counter. It uses a metalized film coating on the inside of the glass envelope as the cathode. It became quite popular in Japan, especially after the 2011 Fukushima disaster. This all-around tube is used in a variety of popular commercially employed handheld portable and laboratory Geiger counters.
