1、医用诊断 X 辐射源即医院用于透视或摄影用的 X 射线机产生的辐射源,是医院的主要检查设备。由于辐射源品质关系到诊断质量以及被检查者健康和安全,因而被列入强制检定计量器具目录。强制检定X射线机的意义,从根本上讲有两条:1、保障成像质量, 有效提高诊断正确性。加强X射线的防护,减少辐射伤害,保护患者得健康。2、测量范围:(0.0001~19.999)cGy,不确定度:U = 5.0%(k=2)。
Radionuclide dose conversion factors, also known as dose coefficients, are used for radionuclide dose calculations. Routes included are oral, inhalation, and external exposure. Separate datasets are m
Radiation therapy for abdominal tumors is challenging because the small intestine is exquisitely radiosensitive. Unfortunately, there are no FDA-approved therapies to prevent or mitigate GI radiotoxic
There is a need to investigate new countermeasures against the detrimental effects of ionizing radiation as deep space exploration missions are on the horizon. Objective: In this systematic review, th
