PROTECTION AGAINST RADIATIONS.
X-rays are hazardous and adequate precautions must be taken when using them. Areas where it is possible
to be exposed to x-rays shall be clearly indicated by using this symbol, which should remind personnel to
observe the safety rules laid down by the laws in force in the country where the equipment is used.
- Control the emission of x-rays from the greatest distance possible (at least 2 meters) from the focal spot
and the x-ray irradiation beam in the opposite direction to where the rays are emitted. For installations in
Canada, the required distance is 3 meters.
- Only the authorised personnel and the patient can remain in the room when x-rays are being emitted.
- The device is provided with an interlock input. If the interlock is activated, it means that the door is open
while the examination is in progress and the ray emission is inhibited. To proceed with the examination,
close the door.
- Make sure that the operator can communicate verbally and visually with the patient during the
examination.
- As for the installation, please refer to the Technical Manual.
- Always protect the patient’s thyroid and gonads under all circumstances.
- Whenever the patient is a child or disabled person requiring the presence of the dentist to keep the
image receiver in position, it is advisable to use a positioner, following the instructions of the
manufacturer of the receiver, and a special glove to protect the hand against x-rays. Use a suitable
overall to protect the rest of the body against exposure to x-rays.
