title: [Hemodialysis procedure in a patient treated with radioactive iodine].
abstract: The treatment of a patient with 131I at activity over 740 mega Becquerel (MBq) must be performed in a nuclear medicine department. Isolation is stopped if the patient radiation level is less than 20 muSv/hour at one meter. As regards patients with chronic renal failure treated with hemodialysis (HD), the first HD session will eliminate the major part of the radioactivity. French regulations do not give definite recommendations for this session. However, it imposes to collect liquid and solid wastes contaminated by radioactivity. Thus, it seems necessary to collect dialysate and solid wastes and to stock them in a room dedicated to radiation decay. The risk for dialysis staff is to be contaminated by an accidental ingestion of a biologic fluid from the patient. The usual protection barriers used during the HD session are sufficient: mask, gloves, overgarments, cap. There is no risk linked to external exposure to radiations. The maximal theoretical dose received by the staff during the session is 65 muSv, while annual maximal dose for public exposed to radiations is 1000 muSv. Although the dosimetric follow-up of dialysis staff is not mandatory, the nuclear medicine department of Marseille University Hospital has decided to do it in an information perspective. The session is performed in the presence of a radiation safety technician who gives film badges and active dosimeters to the dialysis staff. He reports the dialysis staff to the nuclear safety agency (Autorité de sûreté nucléaire).
