Model D Radiation Sensor
The previous blog entry on the uRADMonitor D presented a few details on this new radiation detector, stating that it will be able to detect not only gamma radiation, but also beta and alpha (including radioactive radon sources). One problematic issue was sourcing the proper detector, one that was both sensitive and small to fit […]
uRADMonitor in Shenzhen, China
Unit 1100007D went online in Shenzhen, China, showing slightly elevated radiation readings: This unit is located in an industrial electronics production centre. Its purpose is more connected to future uRADMonitor production than to environmental surveillance, so the readings might go offline from time to time. Other units in that part of the world, include the […]

Two hundred uRADMonitor units
Not long after the 2014 summary announced a first achievement of 100 units deployed globally, the network has already doubled its size, with a total of two hundred units installed or in transit to their new location. The new locations are many and it would be a rather complicated task to name them all in […]
Model A New firmware v111
With the uRADMonitor network covering more ground, constant effort is invested in making the project serve its purpose better. Code improvements come with extra features or better stability, and new firmware updates are released to anyone interested in upgrading their units. Firmware 111 is the latest code released for the uRADMonitor model A units. We […]
The Compensation Capacitor
Normally, the Geiger tube delivers a sharp short pulse, with an abrupt descending path, as the quenching gas very quickly neutralises the conductive ions, and so terminating the current flow. The uRADMonitor pulses appear with a slightly rounded tip because an extra capacitor is added in the circuit, named the “compensation capacitor”. All uRADMonitor model […]
Checking the Geiger tube
The Geiger tubes used in uRADMonitor model A units are mostly the SBM-20 or the SI-29BG, both of Russian provenience, manufactured at military grade specs. Therefore they were meant to resist fluctuations over a wide interval of temperature or pressure. If a tube failure is suspected for a particular uRADMonitor unit, for example when the […]
Howto upgrade your uRADMonitor and graph local statistics
Hi everybody, My first post here to develop my answers in the forum about how to upgrade the firmware and get the local data to create some graphics. The upgrade procedure has been explained by Radhoo in a previous post, but I will add my little grain of salt.
Model A firmware upgrade guide
As a project targeting global coverage, uRADMonitor was designed with all the important features right from the start: the units are plug and play, the network settings are automated via DHCP, the location is estimated automatically based on IP and so turning the unit on is enough to have a new node on the map, […]
A year to remember
2014’s last day is slowly passing by. For what uRADMonitor is concerned, the passing year was one to remember. It was 2014 where this entire project practically started: it moved from an idea to a prototype and then into production, for now to see it expand quickly all over the world. The solution is already […]
Poland on the map with two units
With some of the new units still in transit, or waiting to get installed, a few others are already up an running.

Hard to solder
It’s been another day, full of…soldering. To cover the high demand, I’ve been hard at work producing more units for those interested in helping the network expand. Here’s more than 20 PCBs. Tubes will be added later, also the software, and the calibration tests. It’s a lot of work, but the neat results make it […]
Powering the uRADMonitor via PoE
When I received my URAD Monitor, I was trying to think of the best placement where it would satisfy the requirement to be outdoors but still remain close to a power source. Having worked with PoE WiFi devices before, I contacted Radu to mention a PoE solution I was considering. Since I was able to […]

Producing the uRADMonitor – the circuit boards
The first uRADMonitor units were built by hand as prototypes, a time consuming task involving a lot of attention that often led to results of only satisfactory quality. Very frequently it was the PCBs that simply weren’t good enough when made by hand: defects were frequent and repairing them was nearly impossible. Luckily the usual […]
The Geiger Tubes
The Geiger tube is a gaseous ionization detector that uses the Townsend avalanche phenomenon to produce an easily detectable electronic pulse from as little as a single ionising event due to a radiation particle. It is used for the detection of gamma radiation, X-Rays, and alpha and beta particles. It can also be adapted to […]
New unit in Phoenix, Arizona
