An experience of instrumental estimation of cumulative external doses using single grain luminescence retrospective dosimetry method with quartz containing samples from Fukushima prefecture, Japan

Comparison of calculated beta- and gamma-ray doses after the Fukushima accident with data from single-grain luminescence retrospective dosimetry of quartz inclusions in a brick sample

“…To establish the cause of the dose enhancement near the brick surface, we performed a Monte Carlo simulation of a small brick building with radionuclides uniformly distributed on the ground surface. The calculated results were compared with the data measured by Stepanenko et al [ 17 ]. The depth profiles of the dose in the brick sample for beta rays and gamma rays were estimated separately, and the dose enhancement near the brick surface was discussed.…”

“…Retrospective dosimetry with brick samples has been used to evaluate the gamma-ray dose of the Hiroshima atomic bomb [ 8 – 10 ], the Chernobyl nuclear power plant accident [ 11 – 14 ], and the Semipalatinsk nuclear weapon testing [ 15 , 16 ]. Recently, Stepanenko et al [ 17 ] used retrospective dose evaluation of brick samples to estimate gamma-ray doses and perform beta-ray dose reconstruction for the FDNPP accident with a similar method to that used for a Hiroshima tile sample [ 18 ]. They used a single-grain quartz optically stimulated luminescence (OSL) method (similar to that of Ballarini et al [ 19 ], although layer-by-layer consequences for very thin layers of the sample’s aliquots were used for analysis, with separate dose calibration for each quartz grain) with brick samples taken in 2014 from Odaka, Minami-Soma City, Fukushima Prefecture, Japan [ 17 ].…”
