Radiation Detection Sensors

The Varadis radiation detection sensors, called RADFET (Radiation Sensing Field Effect Transistor), are discrete p-channel MOSFETs optimized for radiation sensitivity. This microelectronic chip, specially engineered to be sensitive to high energy (ionizing) radiation.

Varadis cost-effective RADFETs are small, robust, require no power to detect radiation and can be easily integrated into radiation dosimetry applications.

You can choose to use an individual RADFET for integration into your design, or a Read-Out Module which provides an optimized RADFET read-out while cutting development time and cost.
