Re: Rad reading magnetic drum

[Tom.Denny%em@mailgw.er.doe.gov]

Upon passing around the original message (at end of this message) here at 
work, 
this is the response I got. Hope it provides some insight.

"Tom:

Not knowing what this device looks like, it would be hard to tell.  If it is 
of 
the 1950's or 60's vintage there could very well be a static eliminator 
somewhere in the device. Most of these devices were alpha emitters I believe,
 
and some had Polonium sources in them. We had some static eliminators in a 
reproduction device in the old "Hobby Shop" in Building 881 that had to be 
on 
the source registry.  I dont remember what the source strength was but I 
believe
it was several microcuries.

I was asked to post this question to the board by a friend. A rotating
magnetic
storage drum in a G.E. PAC 4000 process computer system was reading 2 mR/h
on contact. This machine is from the 1950's or 60's. It is about 2 feet in
diameter and 18" deep. It was an early hard drive I believe. Any one have
an idea as to what is causing the rad level?
Thanks,
Roger Moroney
