Probe malfunctions or proximity of the probes to people undergoing certain medical procedures or to radioactive items can cause high readings at a remote station. Weather conditions, including rain and lightning, can cause slightly higher than normal readings. If the map appears to show elevated radiation levels, contact C10 for further information.

This
map shows the area around the Seabrook plant. Each dot shows the
location of one of the C10 monitoring stations. The data on this map
is updated approximately every 15 minutes.
The colors of the dots indicate the most recently reported readings from each station. Light green indicates normal radiation levels; when the levels get higher, the colors change first to dark green, then yellow, then orange, then red. Each dot has an inner and outer part. The inner circle shows the beta level recorded by the Vista 1600 at that station, in counts per minute, and the outer circle shows the gamma level recorded by the Vista 240EC, in mR/hour. |
An empty black circle indicates a station that is off-line. The red side of the compass needle indicates wind direction at the stations that include weather sensors.
