RE: A Question for Power Reactor Types and others with portal monitors.

[Marty.Bourquin@GRACE.COM]

We have a fairly "old" work force and see 4-5% of our people undergoing 

Tc-99M or Tl-201 procedures each year.  The workers receiving Tc-99m can 

usually pass our portals in 1-2 weeks.  The workers who receive Tl-201 

usually cant pass through for at least 2 weeks and some take as long as 

4-5 weeks.



What really amazes me is the percentage of them who are not aware they 

had a nuclear medicine procedure.  They are always amazed when they pass 

the portal or the friskers and everything goes into alarm mode.  They 

end up having to call their doctor and find out what isotope and 

quantity they received.  In our latest case the doctor denied giving him 

anything.  We had to perform a whole body scan on him to identify the 

isotope and then go back to his doctor.  It turned out the doctor in 

question had not performed a nuc medicine procedure but a specialist he 

referred him to had.  Well it keeps my HP staff on their toes - breaks 

up the daily routine.
