Why do you think it isn't ?
There are over 800 million airline passengers in the US each year. If this radiation causes cancers in 1 in a million thats 800 people/year.
- evgen 16y agoIf this procedure causes 800 cancers per year then the flights themselves would be causing nearly a hundred thousand cancer cases per year. The radiation from the scanner is far, far safer than the exposure you receive during the flight that caused you to get scanned in the first place.
- pjscott 16y agoAlso, we should keep in mind that the health effects of radiation may not be something you can linearly extrapolate to low doses, and there is evidence to suggest that they aren't. http://en.wikipedia.org/wiki/Linear_no-threshold_model http://en.wikipedia.org/wiki/Linear_no-threshold_model
