详细介绍
BOMAB全身计数器计量模体，BOMAB模体是BOttle Manikin ABsorber的缩写词，也称为Bottle Absorber Manikin。这些BOMAB模型旨在尽可能模仿人体组织，以便校准全身计数器。可以使用BOMAB模型执行许多测试，并且全身计数设施的测试协议每年都不同。
BOMAB全身计数器计量模体，BOMAB模体由十个不同形状（圆形和椭圆形）的圆柱体组成，尺寸共同构成普通人。高密度聚乙烯，约4.76毫米厚，用于体模的所有部分，因为它被认为在裂变和激活体负荷监测中通常遇到的光子能量范围内具有足够的组织等效性。每个气缸都装有一个50毫米防漏凹陷加油口盖，安装在每个气缸的末端。盖子*关闭时 与表面齐平以允许圆柱体堆叠。整体尺寸的设计符合ICRP 23中描述的参考人的要求。公差保持在+/- 10％之内。
我们的瓶子人体模型吸收器（BOMAB）Phantom（Cat。＃NTSBMP01）提供了一个功能模拟，用于在站立或坐姿的成人人体中散射辐射。它高170厘米。模体的应用包括实际几何校准，性能测量和全身计数器的质量控制测试，其用于内部沉积的放射性核素的体内生物测定。BOMAB体模在核医学的X射线治疗技术中也很有用。

Seamless BOMAB
The BOttle Manikin ABsorption (BOMAB) Phantom is used to calibrate whole body counters.
The seamless BOMAB consists of ten bottles with dimensions as given in Table 1. The seamless BOMAB is composed of polyethylene plastic and constructed without seams in any of the ten bottles.
The volumes of the manufactured version are within 20% of the values specified in Table 1 for cylindrical parts. The total volume of manufactured phantoms tend to have an overall tolerance of 10%.
Each bottle has a recessed screw-type fill port. The screw cap is provided with each bottle and is leak proof when securely tightened.
