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 to the central server of the uRADMonitor network. Real time measurements from each of the units in the network are available on
Following months of improvements, tests and verifications, both in hardware and software, the final model A design has been put into production and first batch of test units is now available. These will be used to expand the network even further. The quality of these units is impressive: small in size and optimised for low power consumption, they are ready to keep an eye on the radiation levels as independent radiation monitors.

This first civilian open network of distributed detectors takes advantage of geographic dispersion, similar design with reasonable calibration, constant autonomous monitoring, all at the cost of very low power consumption.

Getting a unit
To get a device and join the network, see “Join the network”. More hi-res photos of the model A production units are available on the FB page.

Installing the model A outdoors
The previous tips on installing the uRADMonitor detectors apply. You can read them here. The production variant comes with a rubber gasket to seal the enclosure’s top end, protecting the unit from rain. These units can be mounted in direct rain, without any additional protection, if mounted with the cables at the bottom. But direct sun exposure should be avoided.
