Three widely used anthropomorphic phantoms are analysed with regard to their suitability for the efficiency calibration of whole-body counters (WBCs): a Bottle Manikin Absorber (BOMAB) phantom consisting of water-filled plastic containers, a St Petersburg block phantom (Research Institute of Sea Transport Hygiene, St Petersburg) made of polyethylene bricks and a mathematical Medical Internal Radiation Dose (MIRD) phantom, each of them representing a person weighing 70 kg. The analysis was performed by means of Monte Carlo simulations with the Monte Carlo N-Particle transport code using detailed mathematical models of the phantoms and the WBC at Forschungszentrum Jülich (FZJ). The simulated peak efficiencies for the BOMAB phantom and the MIRD phantom agree very well, but the results for the St Petersburg phantom are considerably higher. Therefore, WBCs similar to that at FZJ will probably underestimate the activity of incorporated radionuclides if they are calibrated by means of a St Petersburg phantom. Finally, the results from this work are compared with the conclusions from other studies dealing with block and BOMAB phantoms.
分析了三种广泛使用的人体模型对于全身计数器（WBC）效率校准的适用性：一种是由装满水的塑料容器组成的瓶状人体吸收体（BOMAB）模型，一种是由聚乙烯砖制成的圣彼得堡块状模型（圣彼得堡海洋运输卫生研究所），还有一种是数学医学内照射剂量（MIRD）模型，每个模型都代表一个体重70千克的人。分析是通过使用蒙特卡罗N粒子输运代码进行蒙特卡罗模拟来完成的，使用了于利希研究中心（FZJ）的人体模型和全身计数器的详细数学模型。BOMAB模型和MIRD模型的模拟峰值效率非常吻合，但圣彼得堡模型的结果要高得多。因此，如果使用圣彼得堡模型对类似于FZJ的全身计数器进行校准，可能会低估体内所含放射性核素的活度。最后，将这项工作的结果与其他涉及块状模型和BOMAB模型的研究结论进行了比较。
