Abstract
The paper presents a brief overview of contemporary ELION techniques with
stress on their use for material modification and dosimetry. In the attempt
to avoid some common misjudges of irradiation effects, special attention is
paid to exact definition of irradiation geometry and careful adjustment of
dose rates, which enable a proper elaboration of experimental results. In
particular, effects of g-rays irradiation on properties of commercial optical
fibres, splitters, connectors, and fibre joints are examined, which enables
monitoring of irradiation effects in complex configurations made of materials
with different radiation hardness (resistance). It has been established that
g-rays irradiation of the investigated elements influences, in different
ways, the transmission of laser beam signals of various wavelengths, under
different modulation regimes. After irradiation, the signal attenuation is
noticeably larger, both in optical connectors and optical splitter, than
before it, and the effect increases in time. The effects are more pronounced
at the 99 % than at the 1 % Y-splitter output at both measured wavelengths,
and are more pronounced at 1310 nm than at 1550 nm.
