Forschungszentrum Karlsruhe操作一个部分身体计数器，该计数器设计用于人体内低能光子发射体的体内测量。最近，已经开发出一种数值程序，该程序允许计算该部分体计数器的各个校准因子。该程序基于使用MCNP 5代码对从体内受污染器官或组织到探测器的辐射传输进行的Monte Carlo模拟。为了模拟人体，卡尔斯鲁厄大学生物医学技术研究所的MEET Man数据集已经被应用。将导出的校准因子与使用一些物理体模（如Lawrence Livermore国家实验室躯干体模和纽约大学医学中心的骨体模以及美国超铀和铀登记处）测量的相应值进行比较。
The Forschungszentrum Karlsruhe operates a partial body counter, which is designed for the in vivo measurement of low-energy photon emitters in the human body. Recently, a numerical procedure has been developed which allows for the calculation of individual calibration factors for this partial body counter. The procedure is based on a Monte Carlo simulation of the radiation transport from the contaminated organ or tissue within the body to the detectors using the MCNP5 code. For simulation of the human body, the MEET Man dataset of the Institute of Biomedical Techniques of the University Karlsruhe has been applied. The derived calibration factors were compared with the respective values measured using some physical phantoms such as the Lawrence Livermore National Laboratory torso phantom and the bone phantoms of the New York University Medical Center and the US Transuranium and Uranium Registry.
