Could the radiation is weakened when the display gets into the screen saving
status?
Yes. The radiation produced by CRTs are within recommended daily
allowances for most frequencies (X-Ray, etc.) with the possible
exception of one of the UV bands - that's according to one particular
report I read on this. Modern screens produce less of this stuff that
older ones, possibly because the glass on the front is thicker; in any
case, modern CRT screens are built to more stringent standards.
Reducing brightness will reduce radiation, while increasing the
refresh rate will reduce flicker, another source of fatigue.
When the screen saver comes on, there won't be much change in
radiation or current draw. When the screen goes into a suspend mode,
the CRT scanning beam stops, and current draw is reduced - almost to
off, if the deepest of power saving modes is used. With no scanning
beam in action, radiation should drop to very low levels.
