Not all examples have their reference-outputs (if there's one available) updated at every relase, 'exrdm' is one of these, so it should be just taken as reference. As to the question of whether the example works with the latest release, please see the bug report and fix #846.

As to your second question: The beta spectrum can be aesily reconstructed by selecting the electrons only from the ntuple and you last statement is not correct. In any case exrdm is an "example" to show how to use the G4RadioactiveDecay process, and it is not intended as a general tool to meet all the requirements of simulations radioactive decays.

To your third question: the /gps/pos/centre command assumes a default units of "cm", if the fourth argument is omitted. This is what happend during the excution, but this is not what the code intended as it should have the units specified as "mm". (see line 197 of exrdmDetectorConstruction.cc). The cause of this problem is in line 195 where the carriage-return "\0" is no longer required. Thanks for uncovering this mistake!
