This page has been created to report unusual activity (radiation, temperature, humidity, luminosity, barometric pressure), as recorded by the uRADMonitor, including all the debug data to support the results. I cannot guarantee the measurement precision, I merely present the data recorded by the instruments.
I've developed the uRADMonitor as an Environmental Radiation Surveillance automated monitoring device. Data is gathered in real time, 24/7, and is exported via the Internet to a database online. The data is available in customizable charts for analysis.
An article presenting a simple DIY Geiger Muller counter using the Russian tube SI-22G and a single transistor regulated inverter that puts out 400V, as required by the tube. A very basic detector assembled in 5 minutes. See an operation comparison to the Radex RD1706.
A scintillation probe enclosing the regulated high voltage supply, the signal amplifier, the photomultiplier and the scintillation crystal (NaI). Building a DIY counter for a NaI Scintillation probe. AtMega8 and a bluetooth module for wireless data output. A cheap and easy to build homemade dosimeter with applications in spectroscopy.
