我們的瓶子人體模型吸收器(BOMAB)Phantom(Cat。#NTSBMP01)提供了一個(gè)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(yīng)用包括實(shí)際幾何校準(zhǔn),性能測(cè)量和全身計(jì)數(shù)器的質(zhì)量控制測(cè)試,其用于內(nèi)部沉積的放射性核素的體內(nèi)生物測(cè)定。BOMAB體模在核醫(yī)學(xué)的X射線技術(shù)中也很有用。
BOMAB模體由十個(gè)不同形狀(圓形和橢圓形)的圓柱體組成,尺寸共同構(gòu)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?yàn)樗徽J(rèn)為在裂變和激活體負(fù)荷監(jiān)測(cè)中通常遇到的光子能量范圍內(nèi)具有足夠的組織等效性。每個(gè)氣缸都裝有一個(gè)50毫米防漏凹陷加油口蓋,安裝在每個(gè)氣缸的末端。蓋子關(guān)閉時(shí) 與表面齊平以允許圓柱體堆疊。整體尺寸的設(shè)計(jì)符合ICRP 23中描述的參考人的要求。公差保持在+/- 10%之內(nèi)。
