Most of you here are probably already aware of the network of autonomous low power radiation monitors, uRADMonitor. Besides these attributes, the units are small, low weighted, running on a direct Internet connection, so you don't need a computer to upload data.

Also one of the important characteristics is the detectors use the same tubes, checked against a common reference. So the numbers resulting from all the measurements you see on the world map, can be compared to others in the network. The CPMs get to have a good meaning, but also the absorbed dose approximation, that can be compared to indications of other units commercially available.

The uRADMonitor network is constantly expanding and a new unit went online in Massachusetts.

Here are the initial and the current values registered by this unit:

And the nice constant voltage on tube:

For those interested in getting a unit, there's one currently listed on Ebay for a very low price, or you can get a unit here. Your interest and support for this project is highly appreciated, after all this is an ongoing effort resulting in the first global civilian radiation surveillance network, an accomplishment for the benefit of us all.You can also show your support by spreading the work (here's the facebook page), or by voting (hit the skull icon) the uRADMonitor entry on the hackaday.io contest.
