GENERAL ELECTRIC MEDICAL SYSTEMS AMX-II X-RAY UNIT
1-981
OM A0654E
Under most conditions, cumulative radiation dose to the operator will not exceed recommended maximum
permissible levels. However, as with all radiation-producing devices, a gualified radiation expert should
evaluate situations involving frequent exposures using high kVp and mAs technics to determine if extra
protective devices are necessary.
/
NOTE: Recommended maximum permissible dose to the eyes is 100 mrem/week (NCRP no. 39, p. 89),
where a dose of 1 mrem is produced by an exposure to 1 mR of x-radiation.
ELECTRICAL SHOCK
WARNING:
BATTERY
WARNING:
An audible tone and/or red X-RAY light indicates presence of radiation. If
either indicator is on at any time other than during the expected X-RAY
exposure interval, immediately release the handswitch ROTOR and/or X-RAY
button and turn off main circuit breaker. Do not energize the unit again
until it has been checked by a qualified x-ray serviceman.
This unit contains a 120 volt rechargeable battery inside the cabinet. It can
cause electrical shock even when the unit is not connected to a power outlet.
"The x-ray control access door, shown in Illustration 1-1, can be opened only
by removing the cover. Because of the possible electrical shock and other
hazards present when this cover is removed, it should be removed only by a
trained x-ray serviceman when the unit requires servicing.
Unauthorized persons should not remove the cassette tray shown in
Illustration 1-1.
The cassette tray should not be removed except by or in the presence of a
person thoroughly familiar with safe nickel-cadmium battery service pro-
cedures given in Chapter 8 of the AMX-II X-Ray Unit Service Manual.
Should a metallic object come in contact with the battery terminals, a small
one would vaporize and a large one would become very hot. If the object is,
for example, a ring or a wrist watch, it may weld to a terminal and the wearer
could be severely burned or injured by moiten metal.
The Electrolyte used in nickel-cadmium batteries is a caustic solution of
potassium hydroxide. Serious burns will result if it comes in contact with
any part of the body.
If Electrolyte gets on the skin, wash the affected areas with large quantities
of water; then neutralize skin with vinegar, lemon juice, or 3% acetic acid.
If Electrolyte gets into the eyes, flush with water and GET IMMEDIATE
MEDICAL ATTENTION.
When recharging the battery, the x-ray unit must be located in a large ventila-
ted room. During normal charging conditions and when all batteries are func-
tioning properly, there is little or no gas emitted. Should abnormal conditions
develop, there could be an accumulation of hydrogen gas which if confined in
a small space would be explosive in the presence of a flame or electrical spark.
Whenever the batteries are being charged, a fan ventilates the battery compart-
ment. A hazardous situation will not develop where the overflow from this
compartment is into a large room or a well ventilated small room.
