摘　　要：在过去的十年中,核医学的医疗用途增长非常迅速,截至2017年,核医学的医疗用途是美国人口接触的最大来源。大多数医生难以评估暴露程度或潜在风险。有效剂量提供了电离辐射潜在损害的近似指标,应作为评估涉及电离辐射检查适当性的一个参数。标准射线照相检查的平均有效剂量变化一般在1000 (0.01~10 mSv)左右。计算机断层扫描检查往往范围较窄,但平均有效剂量相对较高(约2~20 mSv),介入手术的平均有效剂量通常为5~70 mSv。大多数核医学程序的平均有效剂量在0.3和20 mSv之间变化。In the past decade,the medical use of nuclear medicine has grown very rapidly.As of 2017,the medical use of nuclear medicine is the largest source of contact for the United States.Most doctors have difficulty in assessing exposure or potential risks.The effective dose provides an approximate indicator of the potential damage of ionizing radiation and should be used as a parameter to assess the appropriateness of the examination involving ionizing radiation.The average effective dose change for standard radiographic examinations is generally around 1000(0.01-10 mSv).Computed tomography scans tend to be narrower,but the average effective dose is relatively high(about 2-20 mSv),and the average effective dose for interventional surgery is usually 5-70 mSv.The average effective dose for most nuclear medicine procedures varies between 0.3 and 20 mSv.
