Aspects of radiation protection in cardiovascular brachytherapy

: In the scope of cardiovascular brachytherapy beta- as well as gamma-ray emitting radionuclides are used. The handling of radioactive sources is within the range of the radiation protection regulations (Strahlenschutzverordnung [StrlSch V]). According to EU guidelines an amendment of the StrlSch V is required by May 2000. The connected reduction of dose limits now should already be taken into consideration when planning irradiation facilities, likewise in cardiovascular brachytherapy. Temporary regulations for equipment that was already in operation before May 2000 are not planned in the new StrlSch V.
