We conducted a monitoring and mapping of the radioactive substances distribution around the Fukushima Daiichi Nuclear Power Plant. In the area of 80 km radius from Fukushima Daiichi Nuclear Power Plant, 
measurements with portable Germanium detectors were conducted at approximately 380 points, and measurements with sureveymeters were done at approximately 6500 points. Newly acquired data were compared to the results obtained by the first or second investigation campaign in 2011.

The results of air dose rates measured by survey meters and 
spectrometry implemented as a fourth distribution investigation campaign in 2013 are to be introduced. In addition, spatial distribution of ratio of deposited Cs-134 and Cs-137 based on results of second campaign in 2011-2012 will be discussed.

The distribution of radioactive cesium were examined by man borne survey method by using KURAMA-II monitoring system. The correlation between the air dose rate measured by man borne survey method and the air dose rate measured by survey meters at 1 m above ground were examined. The correlation between the air dose rate measured by man borne survey method and the air dose rate measured by car borne survey were examined.

Distributions of air dose rate and inventory of radioactive cesium deposited on ground were investigated in 2013, within 80-km radial area centered around the Fukushima Daiichi Nuclear Power Plant. We revealed the characteristics of the time-dependent change of the air dose rate and the inventory by comparison with the measurement results of the past investigations.

We interviewed the life patterns and pathways that are expected when the residents in Evacuation Directive Lift Prepared Area were returned. And then we performed the measurement of the air dose rate that covers the entire life patterns by using KURAMA system. Using the result of that interview and the measurement, we estimated the exposure dose which the residents will receive in daily life when they returned.
