SAFETY PRECAUTIONS
RADIATION: Always consider providing radiation protection for your patient and yourself when
operating the AMX-II.
GOOD OPERATING PRACTICES
© Wear a lead apron while operating the x-ray controls of the AMX-II.
e Step back at least 6 ft. (1.8m) from the AMX-II or to the full extension of the
handswitch cord before making an exposure.
e Always use the proper field sizes and technic factors for each procedure to minimize
x-ray exposure and produce the best diagnostic results.
© When x-raying bed patients, move them as far as possible from nearby beds.
e Ask visitors to step outside the room during an exposure.
e Use gonadal shields for patients whenever possible.
EXPOSURE PROFILE
Illustration 1-1A shows the iso-exposure profile of the AMX-II. This profile shows
the typical scattered radiation levels around an AMX-H using chest radiography
technics.
NOTE: This profile is only an indication of typical scattered radiation levels.
Variations in equipment performance, patient size, technic, geometry, and
radiation measuring devices may cause the profile to vary slightly from the
one shown here.
