[Can we optimize radioprotection for medical workers?].
Implementation of the principle of optimization (ALARA), an essential radiation protection regulations, remains very limited in the medical field, even though 80% of workers whose exposure exceeds 50 mSv are to be found in this domain. The doses measured by legal dosimetry sometimes underestimate the real exposure of workers. It is therefore necessary to optimize the protection of occupational exposure in the medical field. This paper reviews the steps of the optimization procedure with emphasis on specificity of its application in this domain. Operational dosimetry as well as information on the residual risk due to low exposures and a better estimation on the risk/benefit factor for the patient are needed for satisfactory implementation.
