             The purpose of this cross-sectional descriptive study was to examine the knowledge and practice of radiation safety among cardiac catheterization laboratory personnel. The sample of this study consisted of 404 physicians, nurses, nurse aides, patient assistants, radiologic technologists and cardio thoracic technologists who have worked in cardiac catheterization laboratories of 27 public hospitals throughout Thailand. A self-administered questionnaire was used to collect data on personal demographics, knowledge and practice relating to radiation protection. Data were collected from June to November 2017. Data were then analyzed by using mean and standard deviation, percentage, chi square statistic and Pearson’s correlation.

            The results of this study showed that 88.4% of the sample had insufficient knowledge of radiation safety and 35.9% of them had insufficient practice of radiation safety. It was found that radiation protection devices were rarely used, mostly due to the lack of equipment. In addition, there was weak relationship between radiation safety knowledge and practice scores.

            The findings implied that most of the personnel in the cardiac catheterization laboratories had insufficient knowledge and practice of radiation safety, and radiation protection devices in most cardiac catheterization laboratories were inadequate. Therefore, training courses on radiation protection should be held to educate nurses, nurse aides and patient assistants.  Sufficient amount of radiation protection equipment should be provided and regularly checked.
