摘　　要：研发了一款小型直读式个人剂量当量仪。通过能量补偿实现了光子辐射场中个人剂量当量Hp(10)、Hp(0.07)或Hp(3)的实时测量,并且Hp(10)与Hp(0.07)的能量及角响应性能满足国家标准要求,同时给出了剂量仪Hp(3)时的能量及角响应的测试数据。该剂量仪可应用于介入放射学诊疗、γ放射源操作等近距离操作放射源时,工作人员的肢端以及眼睛等局部剂量监测。A small direct reading personal dosimeter was developed.It was achieved the real time measurement of personal dose equivalent Hp（10）,Hp（0.07） or Hp（3） in photon radiation field through the energy compensation,and the energy and Angle response performance of the Hp（10） and Hp（0.07）can meet the requirements of national standard,it also gives the energy and Angle response data of the dosimeter Hp（3） at the same time.The dosimeter can be applied to the operation staff of extremities（hands and feet） and eye lens dose monitoring in interventional radiology treatment and gamma source close operation of the source.
