Scopy uses X-rays and is not without risk (deterministic and stochastic effects) for the patient and the nursing staff present in the room at the time of an endoscopic procedure requiring its use: its use must be reasoned with a benefit/risk balance in favour of carrying out the interventional procedure. In France, there is currently no multicentre study exploring the radiation doses used for each type of endoscopic procedure. Main objective: To define IRL (interventional reference levels) adapted to each type of endoscopic procedure. Secondary objective(s) : * Application of regulatory texts * Assessment of patient radiation protection * Radiation protection assessment for workers
Prospective data collection using an e-CRF available via Easymedstat. Data completed during the endoscopy procedure Completion of a questionnaire by the practitioner who performed the procedure afterwards, including the scopy doses used during the procedure, the type of scopy, the type of intention-to-treat

To define IRL (interventional reference levels) adapted to each type of endoscopic procedure.
IRL is the mean for all endoscopic procedure using scopy, it is calculated by multiplying the PDS in Gy.cm2 with the time during witch the patient as been expose to Xrays during the procedure
Time frame: From enrollment to the end of data collection at 3 months
Application of regulatory texts
yes or no variable : the good delivery of information to the patient about the use of X rays during the procedure ;up-to-date radiation protection training for staff; up-to-date radiation protection training for patient
Time frame: From enrollment to the end of data collection at 3 months
Assessment of patient radiation protection
yes or no variable : optimising X-ray doses
Time frame: From enrollment to the end of data collection at 3 months
Radiation protection assessment for workers
yes or no variable : Wearing ACTIVE and/or PASSIVE dosimeters in accordance with regulations; Wearing personal protective equipment
Time frame: From enrollment to the end of data collection at 3 months
