Circling the world at 17,000 mph in the International Space Station and measuring radiation levels created by particles travelling at 300,000 kilometres per second 220 miles below on Earth at CERN; Varadis RADFETs have become the radiation measurement technology of choice for some of the worlds most prestigious and innovative organisations.
Varadis - A truly Universal Company.
Varadis is a spin-out company from Tyndall National Institute in Cork, Ireland. Tyndall is a leading European research centre in integrated ICT (Information and Communications Technology) hardware and systems. Varadis is leveraging over 30 years of Tyndall technology development in the radiation monitoring space to bring the Varadis RADFET range to global markets.
The Varadis RADFET is a microelectronic chip, specially engineered to be sensitive to high energy (ionising) radiation. The RADFETs are small, robust, require no power to detect radiation, can easily be integrated into electronic systems, and are cost effective.
Varadis RADFETS are today circling the world at 17,000 mph in the International Space Station and 220 miles below on Earth (and a further 100 metres underground) at CERN, measuring radiation levels created by particles travelling at 300,000 kilometres per second around the Large Hadron Collider.

Our Products
The Varadis RADFET is a microelectronic chip, specially engineered to be sensitive to high energy (ionising) radiation. The RADFETs are small, robust, require no power to detect radiation, can easily be integrated into electronic systems, and are cost-effective
Varadis RADFET VT01
Six Lead SOT-23 Plastic Package
Our Plastic RADFET is a discrete p-channel MOSFET optimized for radiation sensitivity. The VT01 is smaller than the Ceramic VT02 and is a great cost efficient option for high volume orders.
Varadis RADFET VT02
Eight Lead Ceramic Side Braze Package
Like the VT01, our VT02 Ceramic RADFET is a p-channel MOSFET optimized for radiation sensitivity. The VT02 is hermetically sealed and slightly larger than the plastic version.
RADFET Reader PRO
For measuring the output voltage of RADFET
Hand-held, battery-operated instrument designed for measuring the output voltage.
Additional RADFETs
Lower/Higher Dosage Options
In addition to our RADFET VT01 & VT02, we have a range of other products (for both higher and lower dosages) that we can supply on request.
