Japan geigermap: at-a-glance
This map visualises crowd-sourced geiger counter readings from across Japan.
Click on the circles to get more information on the readings in each area.
These readings are aggregated by Pachube here.
Measurements are represented in units of microsieverts per hour ( µSv / h). Original readings used the unit nGy/h and I take the approximation 1 Gy = 1 Sv. (See the Wikipedia entry on Sieverts)
