通过非均匀组织等效辐照体模（模拟人）和热释光测定方法，探讨ＢＶ２９型电视Ｘ线机下手术时，人体受Ｘ射线辐射的吸收剂量和年累积吸收剂量。选择Ｘ线机常用管电压电流５５ｋＶ～１．２ｍＡ和８５ｋＶ～２．８ｍＡ，曝光时间１５ｍｉｎ，距球管距离０．５ｍ、１．０ｍ、１．５ｍ情况下，用热释光方法测定模拟人晶状体、甲状腺和性腺三个敏感器官的吸收剂量。根据骨科１９９５年透视手术的数量，估算各敏感器官的年累积吸收剂量。结果各敏感器官离球管越近吸收剂量越高，最大的年累积吸收剂量分别为甲状腺６０８．６μＧｙ，晶状体２７６．７４μＧｙ，性腺３５３．４６μＧｙ，均低于国防放射防护委员会规定的限值，说明在ＢＶ２９型电视Ｘ线机下进行透视手术是安全的
By non-uniform tissue equivalent radiation phantom (simulated human) and thermoluminescence measurement method, to explore the BV29-type TV X-ray machine surgery, the human body by the X-ray radiation absorbed dose and cumulative absorbed dose. Select the commonly used tube X-ray machine voltage and current 55kV ~ 1.2mA and 85kV ~ 2.8mA, exposure time 15min, away from the ball tube distance 0.5m, 1.0m, 1.5m case, the use of thermoluminescence method to simulate the human The absorbed dose of the lens, thyroid gland and gonadal three sensitive organs. According to the number of orthopedic surgery in orthopedics in 1995, the annual cumulative absorbed dose of each sensitive organ was estimated. Results The higher the absorbed dose of each sensitive organ from the tube was, the largest cumulative absorbed dose was 608.6μGy of thyroid gland, 276.74μGy of lens and 353.46μGy of gonad, all of which were lower than the limits prescribed by National Defense Radiation Protection Committee It is safe to carry out fluoroscopy under the BV29 TV X-ray machine
