[ RadSafe ] Any experience in detection of polonium on largescale contamination ?

[stewart farber]

Hi everyone,

Several useful Ludlum large area detectors for measuring alpha contamination 
that would be useful for polonium detection include the 43-5 alpha probe [50 
cm² Alpha Scintillator]  and the Ludlum 43-68 dual gas proportional probe 
[100 cm² open area].

Both of these probes, delivered with a warranty, are available for sale on 
eBay at about one-half list.  For information, see:

Ludlum 44-68 probe:
