Query: Radiation tolerance of opto-electronic components proposed for
  space-based quantum key distribution   Plasma in low earth orbit can damage electronic components and potentially
jeopardise the scientific missions in space. Predicting the accumulated damage
and understanding the components' radiation tolerance are important to mission
planning. In this manuscript we report on the observed radiation tolerance of
single photon detectors and a liquid crystal polarization rotator. We conclude
that an uncooled Si APD could continue to operate from more than a month up to
beyond the lifetime of the satellite depending on the orbit. The polarization
rotator was also unaffected by the exposed dosage.
