Radcon readings of 2, 3 and 4 show the direction of where the NORM background radiation is going.
When the levels are show up on the map, then the NORM background radiation is rising within the 3-month time period. If the Radcon 1 (green) shows up, then the radiation has leveled off or decreasing, as is currently the case in Japan.
Is this because RADCON 5 reports are ONLY issued when a 3-month high is reached?
