International Comparison and Progress of Absorbed Dose to Water in Accelerator Photon Beams
摘要
Abstract
Intemational comparison of absorbed dose to water in accelerator photon beams was implemented by star alignment,with the plot laboratory of the BIPM,and the comparison reference value is the absorbed dose to water measured by the graphite calorimeter.According to the respective radiation quality of medical accelerator,national metrology laboratory choose 2 or 3 radiation beams to do the absolute measurement for absorbed dose to water.7 laboratories have completed the comparison,and the results published in the key comparison database.关键词
