Electromagnetic
Environment
Floors should be wood,
concrete, or ceramic tile. If
floors are covered with
synthetic material, the relative
humidity should be at least
30%.
Mains power quality should
be that of a typical commercial
or hospital environment.
Mains power quality should
be that of a typical commercial
or hospital environment.
Mains power quality should
be that of a typical commercial
or hospital environment. If the
user of the X-ray detector
requires continued operation
during power mains
interruptions, it is
recommended that the system
be powered from an
uninterruptible power supply
or a battery.
Magnetic field should be that
of a typical location in a
typical commercial or hospital
environment.
