摘要：

Radionuclide concentrations in wharf roaches inhabiting coastal areas of Honshu, Japan, were investigated in October 2011 and June 2012. Relative high concentrations of Ag-110m (2.1-127 Bq kg-wet(-1)), Cs-134 (2.6-61 Bq kg-wet(-1)), and Cs-137 (3.5-92 Bq kg-wet(-1)) were detected in specimens from the eastern Honshu areas. Significantly lower Cs-137 concentrations (0.7-1.6 Bq kg-wet(-1)) were detected in specimens from western and northern Honshu. The decay-corrected Cs-137 concentration was significantly inversely correlated with the distance from the Fukushima Dai-ichi Nuclear Power Plant. Thus, wharf roach may serve as a good bioindicator for monitoring radioactive contamination of its habitats.
