Fukushima Prefecture – This article on NHK says parents are calling for lower dose rates for children attending schools contaminated by the accident at Fukushima Daiichi. The current standard allows children to receive the same dose as worker in the nuclear industry.
This international radiation monitoring network was designed by Tim Flanegin, founder of Mineralab and creator of geigercounters.com. Please note that some instruments on the network, such as the Medcom Inspector Alert, utilize a large and highly sensitive “2 inch pancake” detector. Others, such as the Medcom Radalert 100, utilize a smaller detector that has a lower background count rate. This explains some of the variation in data from the various monitoring stations. The larger detectors usually average between 20 and 65 counts per minute, depending on altitude and soil content, and other factors such as probe orientation. The smaller detectors usually average between 12 and 25 counts per minute. Tim’s team is working to identify the differences in the sensors on the network.
