Real-time fibre optic radiation dosimeters for nuclear surgical medicine and nuclear environment monitoring

We presented the mode of operation and the calibration results of miniature fibre optic radiation probes that offer new radiation monitoring opportunities for both nuclear-assisted surgical medicine and nuclear industry. For nuclear medical applications, we showed that the sensitivity of our fibre optic prototype was about ten times larger than a commercial graded probe. With an operational range between 1 mGy/h and 1Gy/h, we showed that our fibre optic radiation probe also has a huge potential for the nuclear industry in applications such as dose mapping in remote-handling applications during decommissioning activities or monitoring underground storage sites for leaks of radioactive materials.
