Optical fibres - Measurement methods and test procedures. Gamma irradiation Ingestion-build-256245 BS EN ISO 6145-6 specifiesWhat is this standard about? This document outlines a method for measuring the steady state response of optical fibres and optical cables exposed to gamma radiation. It can be employed to determine the level of radiation induced attenuation produced in Class B single mode or Class A, category A1 and A2 multimode optical fibres, in either cabled or uncabled form, due to exposure to gamma radiation. The attenuation of cabled and uncabled optical fibres
