Are there any special requirements in mounting Geiger tubes?
Most Geiger tubes have two connections only one for cathode and one for the anode so the electrical connection is very simple. However when mounting the Geiger it is important not to let the Geiger connection become too hot ( i.e.: don’t linger with the soldering iron for too long) as many of the tubes have fragile glass to metal seals which can crack if heat is applied for any length of time. It is often a good idea to sit the tube on a soft material particular if they are used in portable equipment as this will help to absorb any shock and vibration in transit and also take stress off the connections.
