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. 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.
