If a dosimeter is worn through the human scanner, it will receive a minimal dose. Maybe 10 passes, though this scanner will produce 1 mrem (.01 mSv) of dose.
If the dosimeter is passed through the “carry on” luggage scanner, the dosimeter will receive about 5 mrem (.05 mSv) of radiation per pass.
Lastly, if the dosimeter goes through the “checked baggage” scanner, it can receive up to 500 mrem (5.00 mSv) of radiation in one pass. Also, it is common for the dosimeter to report an irregular exposure or beta exposure if it was exposed in the suitcase, because it was likely exposed on an angle.
