Times Cited Count：6 Percentile：73.02(Environmental Sciences)Cs concentrations in ten species of foliose lichens collected within Tsukuba-city in August 2013 ranged from 1.7 to 35 kBq/kg. The relationships between Cs in two dominant species, Dirinaria applanata and Physcia orientalis, and the air dose rate (
Sv/h) at the sampling sites were investigated. Cs in P. orientalis measured about 1 year after the Fukushima nuclear accident was correlated (r
=0.80) more closely with the air dose rate than those measured after about 2 years (r=0.65), possibly demonstrating its continued value as a biomonitor to reflect ambient fall-out levels. In contrast, those of Dirinaria applanata were not correlated with the air dose rate in either year.

Cs released from the TEPCO's Fukushima Dai-ichi Nuclear Power Plant accident has a long half-life of about 30 years, it is necessary to monitor the distribution and its radioecological impact over the long term. Mountainous forests, which accounts for about 70% of Fukushima prefecture, tend to be a sink of radiocesium contamination rather than a source for the contamination of other ecosystems. An understanding of the environmental dynamics of radiocesium in the forest floor of various conditions is important issue, while progressing to the resident return. In this paper, we report on the results of the field investigation into the Cs distribution and the Cs outflow in the mountainous forest of Fukushima, where the wildfire broke out in the spring of 2017.
