Radiation Protection
X-ray radiation can cause serious damage to the health, therefore observe
great care and ensure that protection against X-ray exposure is always applied.
Some of the effects of X-ray radiation are cumulative and may extend over a
period of time. Therefore the X-ray operator should avoid exposure by X-ray
radiation at all times.
Objects in the path of the X-ray beam may produce scattered radiation. The
intensity depends on the energy and intensity of the X-ray exposure, the
material of the object and the distance to the object. Protective measures have
to be taken to prevent exposure through scattered radiation.
Protective measures include:
• structural configuration of the X-ray room (e.g. lead shielded rooms)
• radiation protection for the operators (e.g. personal radiation dosimeters,
lead aprons, radiation protection glasses, mobile lead screens, keep
maximum distance from X-ray source, regular training, etc.)
• protection of patients against unnecessary radiation (e.g. limitation of X-
ray field by collimation, lead shielding, lead aprons, etc.)
Topics:
• Monitoring of Personnel
• Protected area and significant zones of occupancy
