This is an Open Source Digital Radiation Dosimeter, that can be used both as a portable detector, but also as a monitoring station to upload readings to the uRADMonitor network. This project is an update to the previous Geiger Counter Kit 1.0. When used as a portable detector, readings are displayed on the LCD. There is also a speaker that beeps on radiation events or is used to sound an…
Like with all measurements, it will be very hard to find two different devices indicating the same readings, especially when we demand increased precision. We now know that there are no such things as absolute time, absolute space, there are no synchronous clocks. It is the same with the absolute measurements, and in some cases it’s becoming more relevant to observe the change: if we see increasing values, we know…
Note: there is a newer version of this project, KIT1.1, see it here If I was to give this project a version number, the closest match would be the uRADMonitor model B. Finally an open source compact radiation dosimeter, that has an LCD and thus allows mobile use, but also comes with an Ethernet adapter so it can do radiation monitoring (uRADMonitor compatible). Yet, this is not quite the uRADMonitor…
I met some great people today, and I also got a wonderful device for my ongoing experiments as a gift: The UT50 Scintillation probe, manufactured by SC ICPM SA Romania. It features a huge NaI(TL) crystal, with a diameter of 5.5cm and 5.5cm length. The photomultiplier is a British EMI9656KB and the entire device is encapsulated in an aluminum modular cylinder of no more than 24cm total length and 1270g…
The CDV-717 is a very high-range gamma radiation ionization chamber detecting instrument, manufactured by Victoreen back in 1964.
Fixing a CDV700 dosimeter can be difficult because original replacement components are not an easy find.
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.
A digital dosimeter design that can be used with multiple geiger tubes, constructed around the atmega8 microcontroller and a 2×16 LCD. Equipped with a radio Bluetooth module for remote operation.
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.
A story of making a DIY Digital Geiger counter circuit, that can be used with several tubes. Add an enc28j60 Ethernet module and use the data to create graphs available online!
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.
The DRSB-01 is a simple Geiger Counter device that can be used to detect normal vs. dangerous levels of ionizing radiation (gamma and beta).
The CDV700 dosimeter variant 6B (newer) and a few mods to improve functionality: audio connector and bnc connector.
A short review on the Radex RD1706 dosimeter, how good it is, and how can it be compared to other dosimeters, eg. the Terra-P MKS-05.
