After Fukushima blew up (311) a group of people got together and began making radiation detectors.Their efforts received the attention of some financiers and today, they have a relatively large network of mobile and stationary radiation detection volunteers – they are know as Safecast. This may be why URadMonitor’s representation in Japan is nominal. http://safecast.org/tilemap/?y=37.467&x=140.935&z=10&l=2&m=0
