Most of you here are probably already aware of the network of autonomous low power radiation monitors, uRADMonitor - presented in this long project log. 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.

Moving from manually built prototypes to an industrial production line, is a huge step especially for a project in an incipient phase, like uRADMonitor. Yet, with strong determination, obstacles melt away, opening the path for the first civilian environmental surveillance network, available to everyone, at anytime, to offer real time data on radiation level trends all around the Globe. 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 levels measured in CPMs get to have a good meaning, but also the absorbed dose approximation, that can be compared to indications of other units commercially available. But more on this later.

Exciting times for this project, each day brings something new from the Chinese factories building the first PRO uRADMonitor units. Here are the rubber gaskets that will make the enclosures rainproof: More here:

Not yet. For now the case will be rainproof, with the same requirement of mounting it with the connectors at the bottom. I feel it is too complicated to waterproof the connectors in this stage of the project, and brings little gain.
A new revision, model A2 is now available. It will go in parallel to the previous model A, but in limited numbers. It replaces the internal DS18B20 sensor with the BMP180, to keep an eye on the barometric pressure as well.

To comply with the requirements of the HackAday.io “send me to space†competition, I’ve made a short video as an introduction to the uRADMonitor project.
The video presents only a few succinct details, but for more information you can read the additional articles on the uRADMonitor blog. And don’t forget to vote it on HackADay.io (by giving the project a Skull vote) on this link:

They are about to get here . I will post some pics later this week, or the next week, as I get them.
The 7th uRADMonitor detector in the US went online recently and is transmitting from Orlando, Florida. This is one of the newer A2 revision units, that were available in limited quantity a few weeks ago, details on:
