Those authorized to operate, test, participate in or supervise the operation of
the equipment must be thoroughly familiar and comply completely with the
currently established safe exposure factors and procedures described in
publications such as Sub-Chapter J of Title 21 of the Code of Federal
Regulations, "Diagnostic x-ray Systems and their Major Components," and
the National Council on Radiation Protection (NCRP) No. 33, "Medical x-ray
and Gamma-Ray protection for energies up to 10 MeV-Equipment Design
and Use," as revised or replaced in the future.
Failure to observe these warnings may cause serious, genetic or potentially
fatal bodily injuries to the operator or those in the area.
Those working in the immediate area must protect themselves with lead shielding.
These items would include but not necessarily be limited to goggles, thyroid shield,
apron and gloves with a lead equivalency of not less than 0.5 mm.
The best safety rule for x-ray operators is:
“Avoid exposure to the primary beam at all times.”
1.4.4 Monitoring of Personnel
Monitoring of personnel to determine the amount of radiation to which they have
been exposed provides a valuable cross-check to determine whether or not safety
measures are adequate. The most effective method of determining whether or not
the existing protective measures are adequate is the use of instruments to measure
the exposure in Rads. This measurement should be taken at all locations where
the operator or any portion of his body may be during exposure.
A common method of determining whether personnel have been exposed to
excessive radiation is the use of film badges. These are x-ray sensitive film
enclosed in a badge which incorporates metal filters of varying degrees of
transparency to x-ray radiation. Even though this device only measures the
radiation, which reaches the area of the body on which it is worn, it does furnish an
indication of the amount of radiation received.
