Radiation Network–US Monitoring

Radiation Network

[refresh to update map]

SITE–Updated continuously

Nuclear Site                 Alert Level = 100 CPM

How the Map Works:

A growing number of Radiation Monitoring Stations across the country, using various models of GeigerCounters, upload their Radiation Count data in real time to their computer using a Data Cable, and then over the Internet to this web site, all of this accomplished through GeigerGraph for Networks software.

How to Read the Map:

Referring to the Map Legend at the bottom left corner of the map, locate Monitoring Stations around the country that are contributing radiation data to this map as you read this, and watch the numbers on those monitoring stations update as frequently as every minute (your browser will automatically refresh).  The numbers represent radiation Counts per Minute, abbreviated CPM, and under normal conditions, quantify the level of background radiation, i.e. environmental radiation from outer space as well as from the earth’s crust and air.  Depending on your location within the US, your elevation or altitude, and your model of Geiger counter, this background radiation level might average anywhere from 5 to 60 CPM, and while background radiation levels are random, it would be unusual for those levels to exceed 100 CPM.  Thus, the “Alert Level” for the National Radiation Map is 100 CPM, so if you see any Monitoring Stations with CPM value above 100, further indicated by an Alert symbolover those stations, it probably means that some radioactive source above and beyond background radiation is responsible.

Notice the Time and Date Stamp at the bottom center of the Map.  That is Arizona Time, from where we service the Network, and your indication of how recently the Radiation Levels have been updated to the Map.

  1. Newer readings on iodine 131 place it at some 3300 times the safe amount in Pennsylvania.

    We are told that iodine 131 has reached sea water and is being reported 10 miles south of the plant to the tune of 1850 times the normal amount for safety but not to worry as it only has a half life of 8 days. no word on plutonium and how much of this has leaked into the ocean as it has a life of some 24,000 years and one particle ingested into the body begins to destroy it with cancer at some point. It is not there in levels that threaten human life according to TEPCO. So the proclamations that plutonium leakage is nothing to worry about are a fairy tale.
