Propose : This investigation was performed in order to improve the health care of
radiation workers, to predict a risk, to minimize exposure hazard to them and for them
to realize radiation exposure danger when they work radiation area in hospital.
Methods and Materials : The documentation checked regularly for personal radiation
exposure in four university hospitals in Pusan city in Korea between January 1, 1993
and December 31, 1997 were analyzed. There were 458 persons in this documented but
111 persons who worked less then one year were excluded and only 347 persons were
included in this study.
Result : The average of yearly radiation exposure of 347 persons was 1.52¡¾1.35 mSv.
Though it was less than 50mSv, the limitation of radiation in law but 125(36%) people
received higher radiation exposure than non-radiation workers. Radiation workers under
30 year old have received radiation exposure of mean 1.87¡¾1.01mSv/year, mean 1.22¡¾
0.69mSv between 31 and 40 year old and mean 0.97¡¾0.43 mSv/year over 41 year old
(p<0.001). Men received mean 1.67¡¾1.54 mSv/year were higher than woman who
received mean 1.13¡¾0.61 mSv/year(p<0.01). Radiation exposure in the department of
nuclear medicine department in spite of low energy sources os higher than other
department that use radiations in hospital(p<0.05). And the workers who received mean
3.69¡¾1.81 mSv/year in parts of management of radiation sources and injection of
sources to patient receive high radiation exposure in nuclear medicine
department(p<0.01). In department of diagnostic radiology high radiation exposure is in
barium enema rooms where received mean 3.74¡¾1.74 mSv/year and other parts where
they all use fluoroscopy such as angiography room of mean 1.17¡¾0.35 mSv/year and
upper gastrointestinal room of mean 1.74¡¾1.34 mSv/year represented higher radiation
exposure than average radiation exposure in diagnostic radiology (p<0.01). Doctors and
radiation thchnologists received higher radiation exposure of each mean 1.75¡¾
1.17mSv/year and mean 1.60¡¾1.39 mSv/year than other people who work in radiation
area in hospital (p<0.05). Especially young doctors and technologists have the high
opportunity to receive higher radiation exposure.
Conclusion : The training and education of radiation workers for radiation exposure
risks are important and it is necessary to rotate worker on short period in high risk
area. The hospital management has to concern health of radiation workers more and to
put an effort to reduce radiation exposure as low as possible in radiation areas in
hospital.
