Dear Edmond,

What were your criteria? I think that this is the deciding point in his
thread!

Betreff: Re: [ RadSafe ] Re: I131 patient during intercontinental flight



A few years ago when I was the RSO for the USFDA, I had to send an employee
home two days as his readings 

were to high for him to be seated near a pregnant employee.  (The employee
didn't wish to have her pregnancy revealed.)  He only had Tc-99m for a
stress test.  It was the afternoon and next day.

Clayton, Moshe, and others, 

my very very rough calculation indicates 
that 7 mCi of  I131 (26 MBq) 
would expose a neighbour passenger (at 50 cm) 
to a dose rate around 8 microSv per hour of flight. 
This, assuming the worst conditions and considering 
a dose rate from a I131 "point source" of  7.6*10-5 mSv/h per MBq 
and not considering the excretion.
