The Military & Aerospace Electronics take:

3 Dec. 2018 — Photonic sensors convey information with light instead of electric currents in wires. They can measure, transmit, and manipulate streams of photons — typically through optical fibers — and are used to gauge pressure, temperature, distance, magnetic fields, and environmental conditions.

These rugged sensors are attractive because of their small size, weight, and power consumption (SWaP), as well as their tolerance of environmental variables like mechanical vibration. But the general consensus has been that high levels of radiation would modify the optical properties of their silicon, leading to incorrect readings.

So NIST, launched a program to answer those questions. The test results indicate the sensors could be customized for measuring radiation dose in both industrial applications and clinical radiotherapy. The results of its first round of testing is reported in Nature Scientific Reports.
