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?

In a message dated 01/09/2003 12:51:35 PM Pacific Standard Time, FloodJR@NV.DOE.GOV writes:

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.
