Re: Grinding Discs

[DTu7266800@aol.com]

Many grinding discs have Thorium.  The usual procedure is to frisk the 
grinding wheel before they go into the contamination controlled zone, and if 
you detect anything gamma scan the wheel.  The wheel can be released if you 
have the same level of activity upon exiting the area.

Did it ever occur to you that the individual could have contaminated the 
wheel with fission products at another facility?
