Popis:	There are several manufacturers of the newer type of high dose rate (HDR) remote afterloading equipment where a small iridium-192 source can be programmed to stop for a given time at any point in the treatment catheters. The quality assurance phantom described in this paper was developed for a Nucletron microSelectron-HDR (Nucletron International BV, Veenendaal, Netherlands), but as the systems are so similar the device can be modified for any of the HDR systems. Because the complete treatments may be given in just few minutes with HDR remote afterloading equipment it is extremely important to perform adequate quality control (QC) checks on the equipment before use. Several papers have been written on the extent of such procedures to be carried out at calibration (Ezzell, 1989a, b, 1991; Ingham et al, 1989; Jones & Bidmead, 1989; Flynn & Workman, 1991) and before each use (Ingham et al, 1989; Jones, 1989; Ezzell, 1990; Flynn, 1990). As full calibration is carried out only when the iridium-192 source is ch...
