邮寄式辐射剂量验证装置及其作业程序;POSTAL RADIATION DOSE AUDIT DEVICE AND ITS OPERATION PROCEDURES

摘要

本发明揭示了一种邮寄式辐射剂量验证装置及其作业程序，适用于稽核与验证医用加速器之光子与电子射束输出剂量，包括压克力假体、热发光剂量计与验证医用加速器输出剂量之作业程序；压克力假体重量小于1.8kg，方便进行邮寄，面积可涵盖量测医用加速器参考剂量时之10×10cm 2 照野，厚度可提供足够辐射散射量，且配合待验证的医用加速器射束能量，调整覆盖热发光剂量计之压克力材料厚度，以达到电子平衡的要求，进而验证其输出剂量准确性，保障放射治疗品质。 A postal radiation dose audit device and its operation procedures is provided, which is applying to audit and validate the does output of photon and electron beams from medical accelerators. The device includes acrylic phantoms, thermoluminescent dosimeters and operation procedures. Because the weight of acrylic phantoms is lighter than 1.8 kg, the acrylic phantoms could be mailed conveniently. Also, the surface area of phantoms are satisfied with the field size 10 ×
