Abstract：Objective To ensure the normal work and radiation safety of dental panoramic X-ray machine. Methods Air kerma rate, repeatability and quality of radiation output of four kinds of dental panoramic X-ray machines were detected with Piranha X-ray dosimeter. Resulta All the indicators of the four kinds of machines can meet the requirements of JJG744-2004 verification regulation of medical diagnostic X-ray radiation source. Conclusion As an important part of medical verification of dental panoramic X-ray machine, radiation verification can provide reference information for the formulation of radiation verification standard.
