State of the measurement
Nishiogikita Suginami Ward, Tokyo
Total linear distance of 229km geodetic Fukushima Daiichi Nuclear Power Station
Latitude: 35 ° 42 '18 ", longitude: 139 ° 36' 31", height: 48m, 75cm above ground, around the.
Placed in a window facing east first floor wooden mortar housing (indoor)

The vertical axis Geiger counts per minute (CPM), and to the CPM, multiplied by 0.00833, when it becomes μSv/hour.
15CPM is 0.125μSv/hour
16CPM is 0.13328μSv/hour
17CPM is 0.1411μSv/hour
Risk more than 30CPM

Natural radiation (background) is not considered.
"MEAN" refers to the average.
