DIY Geiger Counter Kit 1.1
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.…
Tube: SBM-20M Small Geiger Muller
Pictures: Details: Compact Geiger Muller tube, the SBM-20M shows an excellent sensitivity for its small size. It was designed for hard beta and gamma radiation, and the particular tubes in…
The first prototype
It's been a crazy run, trying to make this happen. After less then one month I now have the first functional hardware iteration or the first prototype. The Portable Environmental…
Comparison of dosimeters
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…
DIY Dosimeter Geiger Counter KIT1.0
Note: there is a newer version of this project, KIT1.1, see it here If I was to give this project a version number, the closest match would be the uRADMonitor…
Tube: STS-5 (СTC-5) Geiger tube
The STS-5 is a geiger tube for hard beta and gamma detection, manufactured in USSR in the 60's, similar in specs to the newer SBM-20.
Tube: SI-3BG (CИ-3БГ) Small Geiger Muller
SI-3BG Geiger tube is suitable for detecting high radiation doses, but finds little use in DIY applications.
Tube: SI-29BG (CИ-29БГ) Sensitive Small Geiger Muller
The SI-29BG comes with a good size / sensitivity ratio. These tubes are suitable for detecting beta and gamma radiation.
Tube: SI-12B (CИ-12Б) Mini Pancake Geiger Muller
The SI12B is a mica window compact Geiger tube, designed for measurement of alpha and soft beta-radiation.
Global radiation monitoring network
EDIT: there is a dedicated blog on this project, here. Make sure to follow it for latest news. A few days ago I announced my intention of creating my first…
First Kickstarter project is closing in!
Preparing for my first Kickstarter project . Let's make it happen!
Repairing a Victoreen CDV-700 6B Dosimeter
Fixing a CDV700 dosimeter can be difficult because original replacement components are not an easy find.
uRADMonitor – Unusual Background Radiation Reports – Explained
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.
Top 10 Radioactive Electronic Tubes
Some of these tubes contain small quantities of Cesium-137, Cobalt-60, Radium-226, Krypton-85. The radioactive elements have been added to increase the electronic response by improving the internal ionization processes.
DIY/Homemade Radiation Geiger Dosimeter
A digital dosimeter design that can be used with multiple geiger tubes, constructed around the atmega8 microcontroller and a 2x16 LCD. Equipped with a radio Bluetooth module for remote operation.
uRADMonitor – Online Radiation monitoring station
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.
DIY/Homemade Geiger Muller Digital Counter V3
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!
DIY/Homemade Geiger Muller Clicker V2
This geiger counter circuit features a regulated high voltage supply, with adjustable output. It can run on a single AA battery (1.5V)
Digital Counter using CD4026
A digital counter using CD4026 for fast event counting as those from Geiger Muller tubes or scintillation probes.
DIY/Homemade Geiger Muller Clicker V1
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.
Kvarts DRSB-01 Dosimeter
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).
Victoreen CDV700 6B Dosimeter Mod (Audio/BNC Connector)
The CDV700 dosimeter variant 6B (newer) and a few mods to improve functionality: audio connector and bnc connector.
Tube: SI-14B (CИ-14Б) Pancake Geiger Muller
The Russian SI-14B is a highly sensitive pancake geiger muller tube .
Radex RD1706 dosimeter
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.
Terra-P Radiation dosimeter MKS-05
The terra-p Radiation dosimeter can be used to measure Gamma, Beta and X-rays.
