Monthly Cs-137 depositions from March 2011 to April 2012 were reported at monitoring stations within about 250 km from the Fukushima Daiichi NPP. The monthly Cs-137 deposition at each station decreased with apparent half-lives of 11-14 d during the period from March to June 2011, and after July 2011 its decrease rates changed. Second peaks of the monthly Cs-137 deposition occurred in February-April 2012, which may be supported by resuspension of Cs-137 bearing particles. (C) 2013 Elsevier Ltd. All rights reserved,
