Don't worry: Most airports do not use backscatter x-rays. The detectors they use most often are using magnetic fields to detect metal. The one that does use x-rays uses such a low dose that you should not worry. One general use backscatter scan radiation dose = 0.01 mrem one day of natural background radiation = ~ 1 mrem (10 backscatter scans) average commercial airplane flight (one way) = 4 mrem.
