You should be aware the international paperwork providing internal typically could use IMBA (Integrated Modules for Bioassay Analysis) for calculation, but at the very lease they likely use ICRP-68 dose coefficients and revised kinetic and dosimetric model of the respiratory tract.

At Susquehanna we treat it just the same. They document it for us upon arrival, if they haven't brought a hard copy from the foreign facility. We use Sentinel for dose tracking, and many of the foreign locations are in the database so that we can contact them for their official records. If we do not receive a response from the facility we keep the dose request in the individual's personnel dosimetry file. It's not often that we run into a facility that we don't get a response from. Typically, the most difficult part is making sense of the response paperwork if it is in another language, but the numbers and units usually make sense even if the rest of the document less clear.

OK Colleagues, I know you ask every incoming contractor and/or employee about previous radiation exposure as they come into your facilities to work in accordance with 10 CFR 20.2104 (nod yes, you know you do). When you ask for the workers' "previous" dose, you mean ALL of their radiation dose, no matter where they got it on-the-job. I also know you are aware that you can accept their word for how much they get, for it is written: "Accept, as a record of the occupational dose that the individual received during the current year, a written signed statement from the individual, or from the individual's most recent employer for work involving radiation exposure, that discloses the nature and the amount of any occupational dose that the individual may have received during the current year". -10 CFR 20.2104(c)(1) So the question I have for you to benchmark: Do you do anything differently to document or record radiation doses they received from INTERNATIONAL work (I mean, other than translate Sieverts to Rem)? Follow-up question for those who answered, "yes": What do you do differently? For those who answered, "no": Thanks for not ignoring my benchmarking request! Respectfully, Dane A.
