Abstract Alpha-cyclodextrin, a six d-glucose cyclic oligosaccharide, has several applications in food and pharmaceuticals, but has also been reported to retain iodine in a stable manner for 16 months. Radioactive iodine, which may cause thyroid cance

The distribution of radiocesium was examined in bamboo shoots, Phyllostachys pubescens, collected from 10 sites located some 41 to 1140 km from the Fukushima Daiichi nuclear power plant, Japan, in the Spring of 2012, 1 year after the Fukushima nuclea

Effect of 2-hydroxypropyl α-cyclodextrin (α-HPCD) on the iodine adsorption onto activated carbon (AC) was investigated. The iodine sorption efficiency increased with the sorption time, but the rate of increase in the sorption efficiency varied depe

The radioactive iodine volatilization inhibition of cyclodextrin and the influence of radiation on this effect were evaluated by observing the change in the radioactive iodine-131 (131I) retention rate in an aqueous solution containing cyclodextrin a

In direct organ measurements, there can be uncertainty to the quantified amount of activity due to variations in detector locations. Here, the authors demonstrate a new use of an imaging plate (IP) for evaluating this uncertainty. The method requires

The effect of temperature and shielding on the lower detection limit of a thyroid I monitoring system was investigated in an anthropomorphic thyroid-neck phantom fitted with an imaging plate. The phantom was loaded with an I aqueous solution and moni
