La radioprotection en endo-urologie

The aim of radioprotection is to protect people against harmful effects of radiation; those radiations come from electromagnetic wave or radioactivity that can be natural or related to human activity. Radiation risk is dose related and biological dose is expressed in millisievert (mSv). Mean dose received from natural radioactivity is about 3 mSv, which is a low and non-dangerous dose. Total annual biological dose received should not exceed 20 mSv a year. In endo-urology image intensifier is the main source of irradiation in operating theatre. Rules for utilisation are detailed.
