In modern brachytherapy, a greast step forward was made in the 1960s in France with the introduction of new radioactive isotopes and new techniques. These innovations spread rapidly across Europe, though no single dosimetry standard had been set by then. In the new millennium, the advances in brachytherapy are further stimulated by the introduction of 3-D imaging techniques and the latest after loading irradiation equipment that use point sources. The international organiyation ICRU (International Commission on Radiation Units) worked out brachytherapy techniques and standardized them in 1985 and in 1997. Due to rapid development of new techniques, the revision is required in order to set new international standards in dosimetry and brachytherapy techniques that will fit to the changed conditions in radiotherapy. Conclusions. This is an outline of radioactive sources that are currently used in brachytherapy, such as Cs-137, Ir-192, Ra-226, Rn-222, Co-60, I-131, I-125, Pd-103, Tu-106 and Cf-252. Izhodišča. V moderni brahiterapiji je bil napravljen velik korak naprej v šestdesetih letih v Franciji z vstopom umetnih radioizotopov in novih radioterapevtskih tehnik. Nove metode so se hitro razširile po Evropi, četudi uporaba doze še ni bila standardizirana. V novem tisočletju brahiterapija doživlja nov zagon z vstopom trodimenzionalnega (3D) načrtovanja obsevanja in novih obsevalnih aparatur, ki uporabljajo točkaste obsevalne vire. Mednarodna organizacija ICRU je zaokrožila in standardizirala brahiterapevtske postopke leta 1985 in 1997. Zaradi hitrega razvoja novih tehnik pa bo kalu spet potrebno priporočilo, ki bo mednarodno predpisalo način predpisovanja doze in brahiterapijskih postopkov v novih razmerah. Zaključki. V članku je podan pregled radioaktivnih izvirov, ki se danes uporabljajo pri obsevanju v brahiterapiji.
