If you are a professional and can prove it, it helps. The first thing the French asked me was if I was a professional. South Africa have stickers on their machines stating that also though the Xray will not affect low ISO film, you may still ask for an inspection. It can't be such an extraordinary request.
How does film get distributed world wide? Is it ever Xray'd? Are we paranoid (I know this has been whipped to death). If you're that paranoid, buy and develop on location.
