Objective: With this study, it is aimed to determine the risk perception and knowledge level of ionizing radiation of health personnel have dosimeters in a training and research hospital.
Material and Methods: This descriptive study was conducted at 1200-beds training and research hospital in Ankara between March 15 and June 15, 2017. Survey method was used as data collection tool. The data were collected with the "Occupational Ionizing Radiation Risk Perception Questionnaire" developed by Manavgat (2011). It was aimed to reach the whole universe but we reached to 72,1% (n = 202). SPSS 21.0 package program was used to analyse of the data.
Results: Participants' knowledge level about ionizing radiation score was 7,48 ± 1,36 (mean) and risk perception score was 8,98 ± 1,73 (mean). 71.3% of the participants never use gonad protectors and 67.8% of them never use glasses, 30.7% use masks sometimes, 41.1% always use lead shielding as personal protective measures.
Conclusions: It was found that the personnel who participated in the research had high occupational ionisomer risk perception and sufficient knowledge level in this area. While the radiation risk perception varies according to the unit, the level of knowledge varies according to the professional title. The importance of personal protective measures should be emphasized and the control mechanism must be established about use of whole personal protective measures. Training of personnel, especially technicians should be kept up to date about radiation, occupational hazards and risks.
