Protection against ionizing radiations
This equipment generates ionizing radiations ( hereinafter called radiations).
Before proceeding with x-ray exposure, be sure that all safety measures in protection against
radiations have been taken.
While using the equipment, the examination room personnel have to respect all necessary protection
rules. In this context, please observe the following rules:
● To protect patients from radiations, use tools suitable for protection against radiations, as well as
the devices supplied together with the x-ray equipment ( for example, diaphragm, spacer, filter)
● Always wear protective clothing. Anti-radiation clothing with an equivalent of 0,35 mm of lead
can reduce the 99,84% of radiations at 50 kV and the 91,2% at 100 kV.
● If it is necessary to stay in the controlled area, please wear a personal dosimeter. The
Manufacturer suggests to define the personal dose that occurs in the workplace under practical
conditions and to use it as basis for precautions against radiations.
● Distance represents the more efficient protection against radiations. Please keep the largest
possible distance from the exposed object and from x-ray complex.
● Avoid to work in the direct irradiation area; if it isn't possible, please protect yourself, Wear
gloves for protection against radiations.
● Always use the lowest collimation of the x-ray area. Check that interested area is completely
exposed. The diffused radiation depends largely on the volume of the object exposed.
● Always check that the x-ray field collimation completely covers the measurement range selected.
● Always select the largest possible distance between focal point and skin in order to minimize the
dose absorbed by the patient.
● Always select the shortest examination time, in this way the radiation dose is considerably
reduced.
● Move the interested area as close as possible to the image intensifier/ cassette / detector.
Radiations exposure is reduced and even optimized.
● Always keep in mind that any material interposed along the path of radiation between the patient
and the image receiver ( for example film) reduces the images quality and increases the dose
absorbed by the patient.
● Always check that there is visual and audible communication between the user and the patient
during all the examination. If necessary keep the communication using technical means such as an
intercom.
● Do not modify or remove safety circuits that under certain conditions prevent the x-ray emission.

Laser light source
Laser radiation
Radiations potentially dangerous for skin and eyes.
► Do not stare directly or through optical instruments at the laser beam
► Do not point the laser beam on the face/eyes of the patient
