adequate. It may reveal inadequate or improper radiation protection practices and
potentially serious radiation exposure situations.
The most effective method of determining whether or not the existing protective
measures are adequate is the use of instruments to measure the exposure. These
measurements should be taken at all locations where the operator, or any portion of the
body may be exposed. Exposure must never exceed the accepted tolerable dose.
A frequently used, but less accurate, method of determining the amount of exposure
is the placement of film at strategic locations. After a specified period of time, develop the
film to determine the amount of radiation.
A common method of determining whether personnel have been exposed to excessive
radiation is the use of personal radiation dosimeters. These consist of x-ray sensitive film
or thermoluminescent material enclosed within a holder that may be worn on the body.
Even though this device only measures the radiation which reaches the area of the body
on which they are worn, they do provide a reasonable indication of the amount of radiation
received.
