Back-scatter scanners are a dose of X-rays. X-rays are tied to increased rates of cancer. A dental x-ray increases risk of cancer about 16/100,000th of a percent.
If you assume backscatter x-rays are 1/100th the dose, it would increase the odds of cancer by 16/10,000,000ths of a percent. So for every 10 million passengers, about 16 would die from cancer as a result.
Since an estimated 600 millions people fly a year, that means an average of 960 *more* people would eventually die from cancer for *each year* scanners are in use. That's higher than the number of people who die from terrorism each year.
