Abstract
We investigated the performance under <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$\gamma $ </tex-math></inline-formula> - and X-rays of an optical-fiber-based distributed dosimeter consisting of an embedded optical time-domain reflectometry (OTDR) interrogator operating at 1610 nm and a phosphorus-doped, single-mode, size-reduced optical fiber (OF). Results show a linear response from <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$10^{-3}$ </tex-math></inline-formula> to <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$10^{2}$ </tex-math></inline-formula> Gy(SiO2), a proper functioning of the interrogator at least up to doses of 80 Gy(SiO2), and performances comparable with standard-sized distributed dosimetry systems found in the literature.
