美國核科技BOMAB全身計數器計量模體，BOMAB模體詳細介紹：

BOMAB是BOttle Manikin ABsorber的縮寫詞，也稱為Bottle Absorber Manikin。這些BOMAB模型旨在盡可能模人體組織，以便校準全身計數器。可以使用BOMAB模型執行許多測試，并且全身計數設施的測試協議每年都不同。

我們的瓶子人體模型吸收器（BOMAB）Phantom（Cat。＃NTSBMP01）提供了一個功能模擬，用于在站立或坐姿的成人人體中散射輻射。它高170厘米。模體的應用包括實際幾何校準，性能測量和全身計數器的質量控制測試，其用于內部沉積的放射性核素的體內生物測定。BOMAB體模在核醫學的X射線技術中也很有用。

BOMAB模體由十個不同形狀（圓形和橢圓形）的圓柱體組成，尺寸共同構成普通人。高密度聚乙烯，約4.76毫米厚，用于體模的所有部分，因為它被認為在裂變和體負荷監測中通常遇到的光子能量范圍內具有足夠的組織等效性。每個氣缸都裝有一個50毫米防漏凹陷加油口蓋，安裝在每個氣缸的末端。蓋子關閉時 與表面齊平以允許圓柱體堆疊。整體尺寸的設計符合ICRP 23中描述的參考人的要求。公差保持在+/- 10％之內。

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.
