Info requested on HARSAW RADON Daughter Analyzer

["Dolf Brits" <dbrits@mepta.pwv.gov.za>]

Hi All

Some years ago HARSAW manufactured a "RADON Daughter Analyser" which coud
determine the air concentration of RaA, RaB and RaC - I have the instruction
manual.

Is this instrument still available?
Did it work correctly ?
Is there any portable instrument that can determine these three isotopes
reliably ?

Thanks for all comments.
