EDA Radon Detector RD200 - UK Vintage Radio Repair and Restoration Discussion Forum

David Simpson · 3rd Oct 2010, 2:57 pm

Guys, Guess this is rare test eq. query. Originally completely u/s, but have got it powered up & producing a numeric lcd display, and the auto/man timer is working.
Would really like at least a cct diagram, prefarably - a handbook/manual.
Plenty of scientific references to the RD200 on google, but the only technical info available is off an American Patent site which has restricted access.
Wondered if any scientific Forum members might be able to help, please ?
A retired scientist has promised me a safe isotope to test it with.

Regards, David
