Re: RADSAFE digest 35

	With the advent of the new Part 20, our disposal options for
	animal carcasses containing radioactive microspheres has 

	become extremely limited. To this end, we would like any 

	information on conversion to non radioactive microsphere
	methods. The investigators normally use 3-4 different 

	microspheres (Ce141,Cr51,Ru103,Nb95).

What's the problem?  Most of the isotopes used in microspheres are  
short lived so the ash can be held for decay.  How does the new  
10CFR20 affect your disposal of microspheres?
