Cleaning the Radiation Shield
The outer surface of the radiation shield should be cleaned when there is excessive dirt and
build-up on the plates. Use a damp cloth to clean the outer edge of each ring.
Note:
Spraying down or using water excessively to clean the radiation shield can damage the sensitive sensors
or alter the data the ISS is transmitting.
Check the radiation shield for debris or insect nests at
least once a year and clean when necessary. A buildup
of material inside the shield reduces its effectiveness
and may cause inaccurate temperature and humidity
readings.
