Any thoughts on the repair of light sensitve Tuff100A probes

[JGinniver@AOL.COM]

Anyone out there with experience of the Tuff100A probe manufactured by RIS 

Corp.   I have a unit which is light sensitive and would like to repair it, 

however having taken it apart this doesn't seem as straightforward as repairing 

standard alpha scintillation probes with separate light tight foil windows and 

scintillators.





Any hints, tips or thoughts would be appreciated.



Thanks Julian

perhaps point out that 'fiddling' with radiological protection instruments is 

my hobby and isn't done for commercial gain.
