Method
We did the recognition survey using 12-item self administrated questionnaire over 2 months in 2001. The questionnaires were sent to 613 physiatrists. Eighty-eight physiatrists of the 613 completed the questionnaires.

Results
Eighty-three of 88 completed the questionnaires were performing their procedure under roentgen environment. The mean procedure time per week was 2.1 hours. Their common procedures doing under roentgen environment were as follows: swallowing videofluoroscopic study (60.2%), voiding cystourethrography (49.3%), arthrography (37.3%), epidurography 25.3%, and so on. 8.5 % of the 83 physiatric interventionists wore the radiation dosimeter and received regular assessment of radiation safety. 62.7% of the participants were wearing one piece apron, and 24.1% wore one piece apron and thyroid shield. Of the radiation related symptoms, fatigue was most common.

Conclusion
We concluded that the special concern and education program to reduce radiation risk are required because of gradual increase of radiation exposure for physiatrists and lack about recognition of radiation exposure. (J Korean Acad Rehab Med 2003; 27: 265-268)
