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.
Statie de monitorizare a radiatiei de fond in Timisoara
Locuiesc in Timisoara, si de curand am terminat o statie de monitorizare a nivelului de radiatii de fond. Cu exceptia catorva institute din tara, care rar dau publice graficele, statia mea e probabil singura alternativa de acest gen, accesibila utilizatorului obisnuit. Acest articol, redactat in romana, prezinta detalii asupra statiei, explica ce este radiatia de fond si cum apare ea, dar si ilustreaza grafice in timp real.
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.
