Can anyone address the issue of dosimeters and airport security?  If a radiation worker with a dosimeter wants to travel on an airliner to visit another facility, should he/she take their own dosimeter with them?  Or, should they use the facility's visitor badge?  Any idea what dose might be expected if the dosimeter goes through the x-ray screening machine?

A dosimeter is obviously to measure your occupational dose, so you should wear it during all professional occasions. And why confuse your records by having to add in "visitor badge" doses?

Simply bring your badge with you, present it to the security guards at the control point and have it bypass all screening devices.

Our field engineers constantly travel in aircraft to perform their professional duties on drilling rigs; this is the standard protocol for them and in many years has not caused a problem.

Of course, there may be slight errors introduced due to variations in background, but this is less important than the maintenance of a decent long term record by avoiding using multiple badges.
