RE: Airport screening and medicine

["Bjorn Cedervall" <bcradsafers@HOTMAIL.COM>]

>Some of my pills have been screened several times.  My question is how much

damage is there to my medications that have been screened several times?  

Has this ever been looked into by anyone?

Almost nothing. I can't give any approx. number (too lazy to check with 

books etc) but regardless of whether it is about X-rays or neutrons I would 

expect any chemical changes to be in the order of 1/100 000 or less. You may 

need 1 000-10 000 Gy to kill bacteria. At higher doses chemical changes may 

become significant. To photograph (X-ray) bags etc much less than 1 Gy 

should be needed.



My personal guesswork only,
