The point is...they should not be carrying their TLD with them from job
to job except in cases like Doug Atkins

Therefore, an employer that requires an
employee to travel, say by jet aircraft at high altitudes, is supposed to
account for the high altitude exposure (not natural background, per se, but
maybe enhanced by the high altitude of the flight) and the additional
exposure from penetrating x-rays at the airport....really?

A dosimeter is
issued to an individual to monitor occupational dose received at a
specific facility. Taking it to a different facility can lead to
attributing dose to the wrong facility. For NRC-regulated
operations, this would probably be regarded as a CFR
violation.
Actually, what the regs say is: "Occupational
dose means the dose received by an individual in the course of employment
in which the individual's assigned duties involve exposure to
radiation or to radioactive material from licensed and unlicensed sources
of radiation, whether in the possession of the licensee or other person.
Occupational dose does not include dose received from background
radiation, from any medical administration the individual has received,
from exposure to individuals administered radioactive materials and
released in accordance with Sec. 35.75, from voluntary participation
in medical research programs, or as a member of the
public."
Again: "exposure...from licensed and unlicensed
sources of radiation, whether in the possession of the licensee or other
person."
That is, ALL licensees, must account for ALL dose, with
exceptions noted in the definitions (i.e., background, medical exposures,
etc.). If YOU are the licensee that knocks a person over the limit,
even if they're getting dose from five other licensees, YOU are the
responsible party.
