Probably Uranium-238 and Thorium-232.  10CFR Part 40.13 defines unimportant 
quantities of source material.  If the compound is less than one-twentieth of 
one percent (0.05 percent) disposal is not regualted by the NRC.  However, you 
might want to coordinate with the state that you reside.  There are 31 states 
that prohibit dispoal of any quantity of radioactive material by conventional 
land fill availability...mike coogen sends

Radnetters:

I received a call from one of the chemical stores on campus regarding the 
disposal of :

thorium nitrate  ~1 lb
uranol (spelling?) nitrate   ~600 g
uranol acetate  ~700 g

does anyone know which isotopes of uranium and thorium are in these 
chemicals and what their specific activity is?

thanks in advance...
