Abstract
The contribution of radiation from Xray baggage scans at airports on dose formation in tooth samples was investigated by electron spin resonance ESR dosimetry and by glass dosimetry This was considered important because tooth samples from population around the Semipalatinsk Nuclear Test Site SNTS Kazakhstan had been transported in the past to Hiroshima University for retrospective dose assessment of these residents Enamel samples and glass dosimeters were therefore examined at checkin time at Kansai airport Osaka Japan Dubai airport Dubai United Arab Emirates and Domodedovo airport Moscow Russia These airports are on the route from Kazakhstan to Japan Three different potential locations of the samples were investigated in pocket without Xray scans in a small bag with four Xray scans and in large luggage with two Xray scans The doses obtained by glass and ESR dosimetry methods were crosscompared As expected doses from Xray examinations measured by glass dosimetry were in the μGy range well below the ESR detection limit and also below the doses measured in enamel samples from residents of the SNTS
