To estimate radiologistś level of knowledge of and their implication in radioprotection.
An anonymous and supervised survey was conducted during a work meeting.
Of the 65 questionnaires handed out, 63 were returned. In general, the radiologists surveyed considered their level of knowledge to be low, and it was statistically demonstrated (P = 0.018) that the level of knowledge they believed they had was related to the number of correct answers. The level of knowledge that radiologists believed they had was also related (p < 0.05) with the years of experience, and it was higher in the more experienced radiologists.
There is an important margin of improvement in knowledge about radiation protection.
