High level Gamma and Neutron radiation resistant non-silica glass
Date announced: 27 Aug 2005
Conventional types of optical glass darken when exposed to gamma or neutron radiation. A glass developed at AFO Research, Inc. maintains its high transmission when exposed to such radiation.
The solarization (darkening) process thwarts the creation of
gamma and neutron radiation resistant fibers or windows. The rapid advances in
space exploration and in the nuclear energy industry have created a need and
potential niche market for such materials. In the present, AFO Research
scientific team synthesized a new type of non-silica-based glass that gamma and
neutron radiation resistant. In the test, the glass was subjected to neutron
fluxes ranging from
3x10^9 to 1x10^14 n/cm2sec and fluences ranging from 2x10^16 to 8.3x10^20 n/cm2.
The glass was transparent in the visible spectral region; when exposed to
radiation for 90 and more days, the glass remained transparent.
