Dosimetric Properties of Watch Glass: A Potential Practical ESR Dosemeter for Nuclear Accidents

ESR response of watch glasses to proton beams

“…Afterwards, the signal keeps decreasing, but more slowly. It remains almost constant after about 300 h. As a comparison, in [16] ( 60 Co c-photon irradiation) the fading during the 24 h after irradiation caused a signal reduc- Table 1 Weight percentages of oxides in watch glasses obtained by means of ArtTAX200.…”

“…The ESR technique was also applied to study the response of various types of glasses (such as window [1][2][3], windscreen [2], watch [16] and commercial [4] glasses) exposed to c and X-rays. In particular, the work of Wu et al [16] describes the first ESR investigation on watch glasses exposed to 60 Co c photons in the context of retrospective dosimetry.…”

Ionizing Radiation Induced Radicals

“…A preliminary study of EPR signals of watch glass carried out by Wu (Wu, K., et al, 1995) and Trompier François (Trompier François, et al, 2008c) had suggested that it was an appropriate dosimeter. A large number of watch glass and display windows of mobile phone with EPR techniques to study the variability of dosimetric properties among the different types of sample.…”

Dose response of xylitol and sorbitol for EPR retrospective dosimetry with applications to chewing gum

“…Other materials found in the pockets of individuals such as sugar (10) , watch glass (11) and mobile phone LCD glass (12) are also suitable. The usefulness of a particular material as a dosemeter can be evaluated by investigating its pertinent properties, in addition to being ubiquitous: the material should have high radiation-induced signal specificity, a low background signal, a low UV-induced signal, a low detection limit, linearity of the signal with dose at low doses and high signal (2) .…”
