title: [Radiation-physical conditions concerning irradiation by means of remote afterloading (author's transl)].
abstract: Afterloading techniques, proposed as early as 1903, came into practical use only during the last two decades. Remote afterloading techniques were introduced clinically when suitable sealed gamma sources became available and reliable equipment were designed, transferring the radiation sources between a shielding container and suitably designed irradiators in the patient. The technique can be used with low or high dose-rate and offers several advantages, such as complete elimination of all radiation protection problems, optimization of the treatment technique - through several means - and possibly increased treatment capacity. Two applications of a particularly flexible system are illustrated. Requirements for the development, advantages with today's technique and possibilities for future development are discussed.
