The Varadis radiation detection sensor is a microelectronic chip, specially engineered to be sensitive to high energy (ionizing) radiation. Small, robust and requiring no power to detect radiation, our cost-effective RADFETs (Radiation Sensing Field Effect Transistor) can be easily integrated into electronic systems. We now have inventory ready to ship in the Varadis VT01. VT03, and VT05 series. More information
