Environmental Research Corporation; Fluid Atomization Generators

[james.g.barnes@att.net]

Good afternoon,

We have some "Fluid Atomization Aerosol Generators" 
manufactured by a company called Environmental Research 
Corporation.  It is our understanding that they were 
used to destaticize air streams used in laser 
applications.  They contain Kr-85 (nominally 1 mCi in the 
1970's, now have decayed to about 0.15 mCi).  We would 
like to return these devices for recycling.

Unfortunately, we cannot find any current reference to 
ERC.  Does anyone know if they are still in business?  
Were they merged with another company; if so, who?

If we cannot recycle them, we would like to dispose of 
them as radioactive waste.  The device appears to contain 
a metal cylinder containing the Kr-85.  This appears to 
be typical of the construction of these types of devices, 
based upon several other models that we possess.  Are 
these cylinders pressurized, or is the Kr-85 gas infused 
at atmospheric pressure?

Thanks in advance.
