I would like to privately discuss 
    experience and procedural information with users of the PerkinElmer 
    BetaScout (manufactured by Hidex as the Triathler).  I am interested in 
    both general operating experience and tritium wipe test 
    procedures.

    Roy, 
    I 
    have worked with it a few years ago, but mostly using the excellent 
    capability of alpha-beta-discrimination for the measurement of radon and 
    even shortlived radon daughters. Please specify your needs as to your 
    measurement requirements and I will see, whether I can help. Since the 
    instrument has a single photomultiplier tube you should be aware, that the 
    background for beta-emitters is high and you have to consider the LLD's you 
    have to achieve.
     
    Best regards,
     
    Franz
