Once upon a time, FedEx pilots used to wear dosimeters. Dumped the used one in a bin in the ol' locker room, and hung a new one on our lanyard. Never heard any feedback about what was indicated on those--good, bad, or ugly--maybe they were just tossed out with the trash? Anyway, they went away. And we don't do that anymore. But we're still losing folks to non-smoking cancers. Knowing my "Rems absorbed last month" would be a lot more useful number than knowing how much gas we saved last quarter.

Reminds me of the time sitting on nuclear alert when we borrowed a Geiger counter and ran it over the surface of the Short Range Attack Missiles loaded in the BUFF's bomb bay. Those were rumored to be "leaky" through their heat shields, and the counter started chirping at a high PRF. Suspicions confirmed. So did we change any procedures as a result? Nope, couldn't change a thing--still had to preflight those jewels every tour. But at least now we KNEW it was a bad thing to hang around in the bomb bay.
