A. Radiation protection
Because exposure to X-ray radiation may damage health, use great care to provide
protection against exposure to the primary beam. Some of the effects of X-ray
radiation are cumulative and may be extended over a period of months or years.
The beat safety regulation for X-ray operator is "Avoid exposure to the primary beam
at all times". The secondary radiation may occur when there is an object on the route
of primary beam.
Intensity of secondary radiation is in accordance with energy and intensity of primary
beam, or atomic number of object on the route. Secondary radiation may be of
greater intensity than that of the radiation reaching the film. Take protective measures
to safeguard against it. One of the effective protective measurements is shielding with
lead. In order to minimize radiation exposure, lead screen, lead impregnated gloves,
aprons, thyroid collars, etc must be used. The lead screen shall contain a minimum of
2.0 mm of lead or equivalent and personal protective devices (aprons, gloves, etc)
must contain a minimum of 0.25mm of lead or equivalent. For confirmation of the
local requirements at your site, please refer to your local radiation protection rules.
The equipment is dangerous to both patient
and operator unless it is properly used.
Only paitent should stay X-ray lab. If other persons inevitably have to stay in the lab
during X-Ray operation, proper protective measurement should be used.
Be careful not to exposure x-lay to unnecessary area. To minimize exposure, use
such items as lead screens, lead impregnated gloves, aprons, thyroid collars, etc.
