[42] Another important factor is the distance between the worker and the source of radiation.

Ionizing radiation is considered a non-threshold carcinogen, but it is difficult to quantify the risk of low radiation exposures. [133] Active millimeter wave scanners emit radiation which is non-ionizing, does not have enough energy to directly damage DNA, and is not known to be genotoxic. [134] [135] [136]

The European Commission issued a report stating that backscatter x-ray scanners pose no known health risk, and that "assuming all other conditions equal", that backscatter x-ray scanners, which expose people to ionizing radiation, should not be used when millimeter-wave scanners that "have less effects on the human body" are available.
