Occupational exposure to ionizing radiation in Jordanian medical institutions

This research survey analyses occupational radiation data 214 Jordanian medical workers during the five-year time period 1990-1994 with the objective of identifying any time dose trend and to determine if annual dose variations exist with regard to sex and job or work status. Comparison of radiation status in Joedanian medical field with that of other countries is a second objective of this study. Biological effects of radiation will, however, not be studied in this research. The statistical analysis of the collected data has shown existence of a decreasing annual dose time trend during the five-year period. This year-to-year variation amy indicate that Jordanian radiation workers are becoming more aware of radiation hazards and they have benefited reasonably from the radiation protection training programmes that were held during that period. These workers are then becoming well abiders by the regulations of the Jordanian radiation authorities. analysis of variance has shown as well that the three factors, which are working status, qualifications and sex, contribute significantly to explaining the variability in annual radiation dose.
