- The fact that x-rays will expose print film to some degree is obvious to
- the casual observer. But where on earth is the evidence that x-rays will
- damage magnetic media? I thought NBS (now NIST) put this rumor to rest
- years ago by thoroughly exposing several tapes and floppies in a research
- reactor with no resultant loss of data. Airport data loss is usually
- attributable to either the metal detectors or to some x-ray machines' power
- supplies.
