Abstract Understanding the actual situation of radiocesium (137Cs) contamination of trees caused by the Fukushima nuclear accident is essential for predicting the future contamination of wood. Particularly important is determining whether the 137Cs d

We investigated the influence of an additional mass bonded on a wooden bar on its apparent Young’s modulus based on a longitudinal vibration theory. Rectangular bars of Sitka spruce (Picea sitchensis Carr.) were used as experimental materials. Afte

We performed dielectric measurements of an evergreen conifer tree, Cryptomeria japonica, impregnated with various aqueous solutions along the fiber direction in the frequency range of 10 MHz to 10 GHz at room temperature to investigate the molecular

To understand the changes in radiocesium (137Cs) concentrations in stem woods after the Fukushima Dai-ichi Nuclear Power Plant (FDNPP) accident, we investigated 137Cs concentrations in the bark, sapwood, heartwood, and whole wood of four major tree s

We developed a method for evaluating the moisture content of sugi logs using an impedance measurement to categorize the effective wood-drying process. The patterns of moisture content distribution in a trunk were found to affect the impedance frequen
