Abstract

Ambient monitor and phantom studies were carried out in the international arrival hall of Taichung Airport, Taiwan. A total of 172 thermoluminescent dosimeters (TLDs) were used for ambient monitoring. The sites of the export conveyor, the outward face of the x-ray scanning chamber, and the x-ray image monitor were assessed as low-radiation areas because the possible annual effective doses were 0.12, 0.39, and 0.16 mSv, all less than 1 mSv per year. In addition, a phantom filled with 126 TLDs was used to simulate a 10-year-old child being exposed by the x-ray baggage scanner. The effective dose was evaluated as 3.39 ± 0.33 μSv/scan, using the tissue weighting factor of the International Commission on Radiological Protection (ICRP) 103 report. This figure is a useful reference should a person be accidentally scanned by the x-ray baggage scanner.
