[ RadSafe ] Cardiolite Fate

[Bill DeForest]

I agree, more like 5 mR/hr at a meter not at 4 meters.

P.S.  That exposure rate sounds quite high to me (5 mR/h at 4 meters).  That would imply 80 mR/h at one meter!!  One would have to give a normal-sized patient ~500 mCi I-131 to get a number like that.  Are you sure of the calibration?  You might also want to double-check the energy response curve.

Dear Group: 
Yesterday I received both Tl-201 & Tc-99m as a intravenous cocktail during a 
cardiac stress test.  The dose was 3 mCi Tl-201 and 20 mCi "Cardiolite" 
Tc-99m for imaging.  By the time I got home, I was quite radioactive, with 
my Ludlum Model 19 measuring 5000 uR/Hr at a distance of 4 meters. 
According to the information that I received, the test amounts to a 3.45 REM 
total effective dose. 
Should I be avoiding my girlfriend for the next week or two?  She works at 
Los Alamos and I don't want to "contaminate" her. 

  

The good news is that no problems were found! 

  

Comments?
