Radium Info Requested

["Mark Anderson" <slhp@HOTMAIL.COM>]

I am interested in practical HP info for the safe handling of unsealed 

radium in 100 uCi quantities.



Information on survey and identfication is NOT needed.  In addition, I'm 

aware of the special disposal issues.



Information in the following areas would be greatly appreciated.



1)  Skin absorption hazard?  Yes/No?  I seem to recall reading about radium 

being somewhat volitile.



2)  Related to the above - Will radium be effectively captured with a HEPA 

filter?  I know the radon daughter will get through - I'm more concerned 

with the radium itself.  If HEPA is not the most appropriate or best filter, 

what is?



3)  I've heard horry stories about radium spreading and contaminating an 

entire facility.  Does radium present special problems in this regard vs. 

other pure isotope material?



4)  Any other special handling precautions?  Tips/Suggestions?  Lessons 

learned?  Pratical experience?



Thanks to all.  Personal reply suggested to keep radsafe volume down unless 

you think others will be interested or benefit.
