Atmospheric concentrations of 212Pb were observed with aerosol samples intermittently from June, 1999, at Kawasaki. The atmospheric concentration of 212Pb showed an unusual and temporal increase in the period from late August to early September, 2000, being inferred to be attributed partly to the 212Pb fallout originating from the 2000 eruption of Miyake-jima volcano, Japan.
