"Original Subject:
Sci. Am. value for Mir radiation exposure

In the latest issue of Scientific American, an American astronaut who
spent 6 months aboard the Mir space station states (p.51) that the
(whole body?) radiation she received was equivalent to about 8 chest
x-rays *per day*.

Could someone translate this into SI units of exposure rate... well, at
least R/day?"

 ----------------------------
A PA chest is around 50 microsieverts.  Therefore 8 per day is about 400 
microsieverts (around 40 mR).
