An approach to assess real workload of medical linear accelerators in Sri Lanka.
Due to the introduction of new radiotherapy treatment techniques and the increased number of cancer patients, there is a higher possibility of redundant workload on radiotherapy machines. Therefore, this study aims to assess the workload in three linear accelerator units. An 8-week survey was conducted in the selected three units, during which all treatment parameters were accumulated. The highest number of treatment sessions per week and highest weekly workload of dose at the isocenter were reported as 465 ± 24 and 1295 ± 93 Gy, respectively in the Varian unit at Apeksha Hospital. The cardinal angle was identified as the 00-300 range in all selected units. The modulation factors for the intensity modulated radiotherapy techniques showed significant variations among the three units. The estimated real weekly workload is quite high compared to previous studies. This study recommends conducting at least a one-year survey, considering all parameters, to obtain more reliable results.
期刊介绍：
Radiation Protection Dosimetry covers all aspects of personal and environmental dosimetry and monitoring, for both ionising and non-ionising radiations. This includes biological aspects, physical concepts, biophysical dosimetry, external and internal personal dosimetry and monitoring, environmental and workplace monitoring, accident dosimetry, and dosimetry related to the protection of patients. Particular emphasis is placed on papers covering the fundamentals of dosimetry; units, radiation quantities and conversion factors. Papers covering archaeological dating are included only if the fundamental measurement method or technique, such as thermoluminescence, has direct application to personal dosimetry measurements. Papers covering the dosimetric aspects of radon or other naturally occurring radioactive materials and low level radiation are included. Animal experiments and ecological sample measurements are not included unless there is a significant relevant content reason.
