[ RadSafe ] Cardiolite Fate

And on that note, I suggest sitting when eliminating to reduce unintentional contamination of the bathroom.  The resident engineer on one job was quite surprised at how much "spray" there was.  Contamination was all around the toilet area...  Also, like Mom said, hand-washing is also important. 

Enjoy your decaying... so happy to learn the test revealed no problems.

That kind of casual contamination would only be a problem for I-131. 
Tc-99m and Tl-201 are eliminated trough urine, not spit, sweat, etc. like 
I-131.  So contamination is almost impossible for most people, draw your own 
conclusions ;)   She will get a little dose being nearby you but at a rate 
of a couple mR per hr, I wouldn't worry too much, you will be decaying down 
fast all the time.

Several years ago in a prior job we had a worker set off the alarm on the 
PCM at our facility, showing facial contamination.  He swore that he hadn't 
been in any production areas but merely walked through the building and had 
to monitor on the way out.  After a lengthy discussion, he remembered his 
wife had some medical procedure done earlier that day and the doctor told 
them not to have any contact for a few days.  But he kissed his wife on his 
way out the door as always.  So we had him spit in a beaker and ran a gamma 
spec.  I-131.  He had to work in the office until he cleared the monitors. 
The poor guy was nicknamed Hotlips ever since.  Quite embarrassing, although 
it could have been much more so if you know what I mean.... 

So the moral of the story is this: 
If your significant other can take a joke, get radioactive and fool around. 
Then send her to work in a radiological facility.

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? 

Dan ii
