Looking for Instruments & Sources

[pcollopy@ix.netcom.com (Peter Collopy )]

I am in the market for the following instruments and sources:

A windowless gas flow proportional counter; preferably an automatic NMC 
or Tennelec w/ RS 232 interface capabilities. Will listen to offers on 
manual counters but prefer an automatic.

A ludlum Model 19, Bicron microrem or microanalyst or similar microR 
meter(s)

Ludlum (or equivalent) 100 cm sqaured gas flow proportional 
contamination detector probes.

Ion chambers with range of 0 to 50 rem/hr. desire to have at least one 
of them for monitoring x-rays below 125 kev, so something similar to 
Victoreen's low energy model would be helpful.

Traceable (to NIST) check sources (both alpha and beta)to be used for 
setting efficiences for counting equipment. Am looking for both disk 
and point source geometries. The sources must have the original 
paperwork and have no surface deterioration (particularly the alpha 
sources).

If you want to sell or give away (just a slight hope) any of the above 
contact me at any of the following:

E-mail: pcollopy@ix.netcom.com
Work phone: 412-233-0660

If you call ask for Tim Knapp if I am not in.

Thanks in advance for all who reply or pass on the request.
