    Analysis of <sup>137</sup>Cs trapped in biomass in highly contaminated zones is crucial in predicting the long-term fate of <sup>137</sup>Cs following the explosion at the Fukushima Daiichi Nuclear Power Plant. We surveyed forest 20–50 km from the plant in July and September 2011 to evaluate <sup>137</sup>Cs trapped in biomass within 20 km of the plant. We determined the ambient dose rate and collected forest soils and twigs at 150 sampling points. Removability from the canopy was evaluated by washing leaves and branches with water and organic solvents. The biomass of the forest canopy was then calculated. <sup>137</sup>Cs fallout was simulated with an atmospheric transport model. The modeled dose rate agreed with observations (<i>n</i> = 24) (<i>r</i> = 0.62; <i>p</i> < 0.01). Washing experiments demonstrated that unremovable portions accounted for 53.9 ± 6.4% of <sup>137</sup>Cs trapped by deciduous canopy (<i>n</i> = 4) and 59.3 ± 13.8% of <sup>137</sup>Cs trapped by evergreen canopy (<i>n</i> = 10). In total, it was estimated that 74.5 × 10<sup>12</sup> Bq was trapped by canopy in the forest within the no-go zone, with 44.2 × 10<sup>12</sup> Bq allocated to unremovable portions, and that 0.86% of the total release was trapped in biomass as of September 2011

    <p>The horizontal bars show the frequencies (the <i>x</i>-axis is the number of individual samples in each class). The black line boxes at the center of each graph show the first, second, and third quartiles. The lower whisker indicates the lowest value within the −1.5 interquartile range of the first quartile. The upper whisker indicates the highest value within the +1.5 interquartile range of the third quartile. Outlying values are shown as dots. The blue bars on the right-hand sides of the graphs are the means and standard deviations.</p

    <p>(A) Some <sup>a)</sup>Family 2 and <sup>b)</sup>Family 3 members have been reported previously [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0154827#pone.0154827.ref013" target="_blank">13</a>, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0154827#pone.0154827.ref014" target="_blank">14</a>]. Black and white symbols indicate affected and unaffected individuals, respectively. Gray symbols indicate individuals with unknown phenotypic status. Squares and circles indicate males and females, respectively. Slashes indicate deceased individuals. “P” indicates probands. Blue arrows indicate exome sequenced individuals. * indicates linkage analysis performed individuals. The genotype of <i>SCN11A</i> p.R222H (Family 1, 2, 4, 5 and 6) or <i>SCN11A</i> p.R222S (Family 3) for each individual is illustrated. (B) Sequence chromatography of the identified <i>SCN11A</i> mutations.</p

    <p>Exome analysis was performed for three affected members in Family 1, four affected and four unaffected members in Family 2, and two affected and one unaffected member in Family 3. Exome data was processed through seven filtering steps: (1) non-synonymous, (2) read depth ≥ 8, (3) not registered in dbSNP135, (4) MAF < 0.01 in Japanese patients from 1000 Genomes database, (5) heterozygote in affected members and not present in unaffected members, (6) located on 3p22 linkage region, and (7) variants in the same gene among all three families. Numbers in boxes represent the numbers of variants after each filtering step.</p
