EPEX Omniflex IV System Service Manual
Safety Information 1-17
A frequently used, but less accurate, method of determining the amount of
exposure is placement of film at strategic locations. After a specified
period of time, develop the film to determine the amount of radiation.
Fluorescent screens (used in a darkened room) may also be used to detect
excessive radiation.
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 that incorporates metal filters of varying degrees
of transparency to X-ray radiation. Even though this device only measures
the radiation reaching the area of the body on which it is worn, it does
provide an indication of the amount of radiation received.
Radiation Protection Survey
A radiation protection survey must be made by a qualified expert after
every change in equipment or change in operating conditions which might
significantly increase the probability of personnel receiving more than the
maximum permissible dose equivalent.
