Evaluation of environmental dose at JCO using luminescence from quartz stimulated by blue light

Evaluation of environmental dose at JCO using luminescence from quartz stimulated by blue light

Radiation Protection Dosimetry 94(4): 329-333

The environmental dose due to the recent nuclear accident at JCO, Japan, was estimated using luminescence optically stimulated from unheated quartz. Two methods originally developed for dating analysis, the single aliquot additive dose method and the single aliquot regeneration added dose method, were employed to confirm the dose rate. Consistent results were obtained from both methods and from thermoluminescence measurements. Although the dose rate values had lower precision than can be obtained from heated materials, it is suggested that luminescence from sedimentary quartz can usefully be employed in retrosepective dosimetry.
