Dosimetry is typically issued to measure occupational dose at a particular
licensee. Dosimetry issued by one licensee should not be used (IMHO) to
measure dose from another licensee. In Doug's case, they are the licensee
at mobile locations for performing well logging and the like. They are
using their licensed sources in multiple locations where taking their TLD's
along for the ride would be appropriate. Taking one licensees TLD to
measure occupational exposure from another licensee would not be
appropriate. It is the licensee's responsibility to measure an individuals
dose...not the individuals to ensure it IS measured... Having multiple
badges is no problem as the paperwork burden falls on the licensee who measures
the dose (if necessary in the first place). The monitored individual would
have a few more pieces of paper to keep track of is all. Just my
opinion

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.
