Concerned about nuclear radiation levels, due to fallout from damaged nuclear reactors, nuclear tests, or other events?
Radiation Map Tracker connects to our extensive network of constantly updating, real time, nuclear radiation detectors, all run by volunteers, not government agencies. This app lets you determine what levels of radiation are being reported at various locations around the world. You can scroll around the map and zoom in on readings. Readings are continuously updated every few minutes.
It displays the current ionizing radiation reading from these detectors on an easy to use world map, in uR/hr, one of the standard units of measurement for radiation. You can scroll around and zoom in to your area. Typical background (naturally occurring) radiation values near sea level are in the 10 to 20 uR/hr range. Higher readings naturally occur at higher elevations due to cosmic rays from outer space.
Tapping on one of the readings will bring up a chart of the last few days worth of readings. You can even smooth out the variations by adjusting the number of samples averaged per plotted point, to bring out subtle variations.
Buy a copy of Radiation Map Tracker, and you'll never be in the dark about nuclear radiation levels again.

Monitoring Glen Rose Plant
I started using this app while researching radiation exposure planning. With a nuclear plant nearby, I had discovered reports of high levels of over 300 for several days a few years back. The reports were from the public and stated even with multiple calls to the plant (one posing as a higher govt agency), no release of information was given out to the public.
As I searched, this was the only option I found for real time monitoring. There were originally 2 sites right at the plant reporting. Those went away leaving only 1 in the DFW area.
Good mobile version of website
Those of you calling this a waste... You're idiots!!! Now pay attention: black cat systems makes hardware radiation detectors that interface w computers. This is not a government run service, it's strictly voluntary. When an owner of the hardware is testing the radiation level, it registers on a map for all to see. The more people testing, the more readings. This app is a mobile version of their map on the website, nothing more, nothing less and it's worth a buck for me to have access to the info. If there's no reading in your area do us all a favor and get some friends together, buy a monitor unit, connect it to your computer and let us all see what your readings are. Oh and I don't work for the company, I'm just a guy on the west coast concerned about the impending Fukushima disaster.
