		Paul,

		Thanks for the clarification on the problem with the
GammaMed HDR units.   The Bulletin speaks for itself.   The problem appears
to be a separation from the drive mechanism and not a "break" between the
source and the drive cable as my note indicated.

		Theratronics International Limited has issued a "User
Bulletin" to GammaMed

source cable 
		separation. 
		     
		CLARIFICATION HERE:
		     
		The bulletin refers to 4 incidents in which "...the source
cable became 
		separated from the driving mechanism." NOT separation of the
source from the 
		cable!...as grammatically semaphored in Mr. Myers' opening
sentence above.
		     
		BIG, HUGE, GIGANTIC DIFFERENCE - Let's be more careful out
there, even as we

		The bulletin has been sent to GammaMed 12i and 12it high
dose rate afterloader 
		users and to the radiation control programs in the Agreement
States.  The 
		bulletin describing Theratronics recommendations to users
and actions being 
		taken to remedy the situation is now posted at the OSP web
site's "What's New" 
		area.
