Although the X-ray dosage supplied by dental radiology appliances is on
average low and distributed over a relatively small surface, the operator
must take the necessary precautions and/or follow the safety procedures
for both himself and the patient during an exposure. We recommend
that the X-ray activation always be commanded from an X-ray protected
area via remote control. If it is necessary to operate the exposure near
the patient, remain at the maximum distance allowed by the remote
control cable in the direction opposite to the emission of the rays, at a
distance of at least 78 ¾ inches (2 meters) from both the radiation
source and patient.

Environmental risk and disposal
A number of machine parts contain materials and liquids that upon
completion of the machine’s life cycle must be disposed of at recovery
centers established by the local health units.
The machine contains the following materials and/or components:
•Tubehead: dielectric oil, lead, copper, iron, aluminum, glass,
tungsten, beryllium
•Control box and remote control: iron, copper, glass resin, non-
biodegradable plastic casings
•Column, rotating arm, exten ion : iron, lead, aluminum, copper,
non-biodegradable plastic materials, glass resin.
WARNING:
Before disassembling the parts, lock the counterweight of the slider
inserted in the column. This is possible only after having slid the slider
all the way down and inserted a pin approximately 25cm in length and
8mm in diameter. Once the pin has been inserted, move the slider
towards the top until the counterweight rests on the pin. Remove the
tubehead and some of the parts of the rotating arm. Holding the slider
firmly, remove the pin and move the slider towards the top to the
metallic stop of the column. At this point, remove all the remaining
parts.
