Model A – Production Ready!

The uRADMonitor Project is a network of radiation detectors covering locations all over the Globe. The Model A is the first designed, it is an automated GM detector in a rugged aluminium housing which responds predominantly although not exclusively to gamma radiation. Count rate data is recorded and transmitted continuously via built in Ethernet adapter […]

Observations on diurnal indoor variations in gamma ray count rates

Richard Prettyman, August 2014 Background A close correlation between gamma count rate at ground level, and soil derived Rn-222 flux has been demonstrated in work which has also studied the effects of meteorological and diurnal factors on Rn out-gassing and hence gamma count rate (Szegvary et al, 2007). Under conditions of settled weather with no […]

Server software improvements

The uRADMonitor project has a complex architecture, involving both hardware and software. The software level also has two separate components, one is the client firmware – the software running on the dosimeter’s microcontroller, and the other is the software running on the server. The last posts have shown a lot of progress on the hardware […]

The second unit in Florida, USA

Just a day or two after announcing the first uRADMonitor unit in Orlando, Florida, a new unit went online, 1200000E, not far from the first. The way the unit was mounted looks highly professional, and it gets the best score so far for correctly following the installation instructions. The first measurements indicate very low radiation […]

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

The second uRADMonitor unit in Arizona just went online. Unlike the other unit to the North – that is run at higher altitude and shows increased readings, the new unit measures an average of 11.3CPM (on a SI29BG tube), approximated for the background radiation to a dose of 0.11uSv/h, not unlike what it has seen […]

uRADMonitor model A2 with Barometric pressure sensor

Here is a revision of the current Model A uRADMonitor detector. Codenamed the model A2, it replaces the internal DS18B20 temperature sensor with the more versatile BMP180. The BMP180 is a low power, high resolution temperature and barometric pressure sensor, manufactured by Bosch. It comes with pre-calibration parameters that are used for accurate measurements. The […]

Unit in Netherlands up and running

A new unit went online, in a location close to Amsterdam. The new detector is the first in Netherlands, covering more ground as the network expands. The current measurements show a low background radiation level, only 0.09uSv/h. Here are the initial measurements, performed in Timisoara, Romania, before sending the unit: And here is the same […]

Producing the uRADMonitor – the rubber gaskets

As the uRADMonitor Model A is intended as a environmental radiation surveillance tool, that should be run outdoors, we’ve designed a rubber gasket for the aluminium enclosures, to make sure rain will not get in to damage the components. Now finally we saw the first components getting out of their factories and wanted to share […]

Producing the uRADMonitor – the aluminium enclosure

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 […]

A long story short

In the beginning there was the passion for technology. I decided to start a blog and write about the things I’ve built. I was more into high voltage, physics and various experiments, cool, but with little or zero use to those around me. Then I decided it was time to build something useful, to put […]
