RADFET -- Radiation Sensors

The Tyndall National Institute is renowned for the development of small microelectronic chips optimised for radiation sensing, known as RADFETs. The RADFET has an advantage over other types of dosimeters in that it is small, low-cost, and with very low power consumption. Tyndall has developed a range of RADFETs that are already in use commercially in radiotherapy clinics, high energy physics laboratories, and spacecraft.

For example, almost 50% of all cancer patients in Europe and North America will receive radiotherapy at some point during their cancer treatment. Tyndall has been working with US company, Sicel Technologies, on RADFET development and supply for Sicel's two novel radiation detectors for quality assurance of radiotherapy -- OneDose and DVS. OneDose measures radiation dose on skin through the use of a small, disposable adhesive patch. The patch is read out by a handheld reader; the results are accurate and immediate. Even more unique, DVS (Dose Verification System) is a wireless implantable sensor used to measure the amount of radiation exactly at the location of the tumour or surrounding tissue. OneDose and DVS have been commercially available for several years; DVS is the first and only implantable dosimeter on the market. In other applications, Tyndall RADFETs are currently installed in radiation monitors along the Large Hadron Collider (LHC) ring in CERN and are flying on European, US, Japanese, and Chinese research and commercial satellites.

Tyndall is developing a new RADFET device for monitoring of health and safety of workers in radiation environments in parallel with an effort to enhance RADFET presence in existing application areas.
