Pinching and Collision Hazards
CAUTION!
Ensure that while using any product that can be lowered, raised or moved in
different directions, neither yourself (operator), the patient or any third party
finds themselves in a hazardous position (area of movement). Remove all
objects (e.g. chairs, pushcarts) from known collision areas.
Be aware that careless or improper adjustment of the radiographic system
(movement of column, detector Bucky, Vertical Bucky wall stand and table
top) can lead to damage of the X-Ray components, unusable X-Ray images
and injury to the patient. Failure to pay attention can lead to damage of the
radiographic system as well as external objects.
2.1.5
Explosion protection
These radiographic system is not designated for use within areas with explosive hazards.
2.1.6
Radiation protection
X-Ray radiation can pose a hazard to patients and other people when the regulations regarding the
operation of X-Ray systems are not followed.
For this reason, the basic principles of radiation protection are of the highest priority and must be
followed without exception:
•
Distance from the radiation source
The dosage is reduced as a factor of the square of the distance from a (dot shaped) radiation source.
Double the distance ¼ dose, triple the distance 1/9 dose
•
Keep the exposure time as short as possible
The dosage is directly correlated with the exposure time. A half exposure time results in a radiation
dose half that of a full exposure. (This is especially pertinent with fluoroscopy, as X-Ray images have
predetermined mAs).
•
Utilize shielding and protective clothing
The protective value grows exponentially with the thickness of the shielding. Two half-value layer
thickness (HVL) weaken (homogeneous) radiation to ¼, 3 HVL to 1/8, und 10 HVL to less than 1/1000
of the original value.
•
Do not reach into the direct X-Ray beam
The dosage in a un-weakened-Ray beam is around 100 times larger than that in the scattered
radiation.
•
Use personal dosage meters in working with radiation (X-Rays), the use of personal dosage
monitors is suggested.
The X-Ray images are principally triggered from behind a protective wall. For the creation of images
near the reproductive organs use the maximum available protection (e.g. testicular shielding or lead
covers)
People that must remain close to the patient are required to wear protective clothing (e.g. lead apron).
This counts for maintenance and installation work as well.
2.1.7
Ventilation
It is important to ensure that the air exchange of the X-Ray generator within the system is not hindered.
The ambient air temperature is not allowed to exceed 40°C.
2.1.8
Interaction with external devices
Unwanted interaction with external devices is not known.
