Scintillation Materials in Kharkiv , Ukraine , the Lawrence Livermore National

School in Monterey , CA
developed UV sensors for solar radiation using advanced zinc selenide-based
Schottky photodiodes. These sensors are characterized by high sensitivity,
selectivity, radiation stability, reliability and low cost, allowing
measurement of both UV radiation intensity and accumulated dose. They enable
the collection of critical data to improve the understanding of climate
variation, and characterization and evaluation of the effects of global climate
parameters such as ozone layer depletion, the “greenhouse effect”, and
atmospheric contamination by tropospheric ozone.
In
addition, the project provided the basis for mass production of different types
of ionizing radiation detectors with world-class performance parameters. The
creation of these UV sensors and a prototype dosimeter, with support from a
CRDF Global grant, was based on new technology possessed and developed by the
project participants. Further improvement of the developed UV-sensors and
dosimeter system will facilitate their wide use in climate measurements for
stationary and portable weather stations, as well as for biological studies of
the effects of solar UV radiation on ecosystems, the oceans of the world,
living organisms and humans. The U.S.
and Ukraine
teams will continue to work to ensure the transfer of the project’s promising
science and technology developments to an industrial base which will support
future large-scale production of modern equipment for solar UV monitoring and
improving climate change research.
