Abstract
Whole body and wrist exposure to x-radiation were documented in a study of individuals involved in airport baggage inspection operations. Radiation exposure was monitored for 72 security personnel at five major United States airports. Each worker wore a special badge for a 2 week period to measure radiation exposure. An investigation was also made of at least one model of each baggage x- ray system in use during this period of study. X-ray units at airports were operated by security personal, who were not generally trained in the use of x-ray equipment. They were required to wear a whole body monitoring device such as a film badge or thermoluminescent dosimeter. However, the badges commercially available were not sensitive enough to measure the low energy x-ray exposures below 50 milliroentgens (mR). The specially designed badges used in this study contained four thermoluminescent dosimeter chips, two lithium-fluoride and two calcium-fluoride. Detection at extremely low x-ray exposures was possible as corrections could be made for the energy dependence of the thermoluminescent dosimeters. Measurements of x-ray exposure ranged from 0 to 16.4mR over the 2 week period. There was little difference noted between whole body and wrist exposures. None of the measured exposures exceeded the limits set by OSHA as acceptable for ionizing radiation.
