Remote afterloading of low dose rate (LDR), medium dose rate (MDR), and high dose rate (HDR) radioactive materials for brachytherapy is increasingly practiced in the United States. This report presents the advantages and disadvantages of the units, lists some commercial remote afterloaders and their features, and reviews facility requirements, radiological safety, licensing and license compliance, calibration methods, acceptance testing, quality assurance, and isodose computation.
