TL;DR: The radiocesium migration in undisturbed forest and grassland soils at Fukushima contaminated area has been shown to be faster as compared to the Chernobyl 30-km zone during the first three years after the accidents.

TL;DR: Seven different types of thio- and/or amine-modified cellulose resin materials were synthesized and their mercury (II) ion adsorption properties determined, and the o-benzenedithiol- and o-aminothiophenol- modified cellulosic resins were found to be very effective in removing mercury ( II) ions from strongly acidic media.

TL;DR: Cross-linked acrylic ester microparticles with absorbed fluorescent probe molecules, such as fluorescein and acridine orange, were successfully fabricated and employed as "turn-on" fluorescent sensors for the detection and determination of ammonia and organic amine vapor concentrations.

TL;DR: Analysis of the flux structures shows that up to percents of the total radiocesium activity in the ecosystem may be involved into biogenic cycling.

TL;DR: It is shown that the young trees of Japanese red pine (Pinus densiflora) are sensitive to radiation, and irradiation induced cancellation of the apical dominance in this species is similar to that observed in young trees growing in the Chernobyl zone.
