As mentioned in question #7, the precise line of force for the correction is revealed by the x-rays. NUCCA doctors spend a significant amount of time analyzing the x-rays to find out the exact misalignment pattern (there are around 10,000 possibilities!) for each person as well as the most appropriate plan to correct that misalignment. X-rays are taken after the first adjustment to verify that the correction looks just as good on the inside as it does on the outside; this check is another thing that separates NUCCA chiropractors from many other chiropractors – we can evaluate the exact percentage of the correction! NUCCA was the first chiropractic technique to start using filters, which eliminates unnecessary radiation. Therefore, a NUCCA x-ray series is less than 0.22 mrems of radiation. In comparison, a flight from LA to Paris is 4.8 mrems, and whole mouth dental x-rays are 310 mrems. The NAS (National Academy of Sciences) defines a whole body single exposure of 50,000 mrems (50 rems) to be a high exposure.
