The disclosed system and method employs an autoradiography approach in which particles radiated by the radioactive configuration inside the tissue are detected. Once detected, the display of the source of particles inside the tissue is reconstructed for viewing and analysis.バレット,ハリソン エイチ...
检测alpha、beta 和伽玛辐射 项目 2024/07/26 3 个参与者 反馈 获取材料 地球的磁层是一个巨大的磁力泡。 磁层保护我们免受严重的辐射暴露,并偏转大多数这些辐射粒子。 由于国际空间站处于磁层内的低地球轨道,因此宇航员也可以获得相当程度的防辐射保护。 在此实验室中,学生使用盖革计数器测量环境中的辐射水平。

RadiationHelper是用于以下方面的数据分析工具:1.使用实验数据(由alpha-beta设备获取的计数)进行总的alpha和beta辐射测量和检测器校准。 2.使用实验数据(通过诸如Assayer,Gamma Vision,Maestro等采集软件获取的光谱)进行伽马光谱测量和检测器校准3.可以使用蒙特卡洛模拟技术从理论上计算出总的α,β,伽马检测器效率和伽马峰...
Alpha (α) keratins are found in all vertebrates, while beta (β) keratins are found exclusively in reptiles and birds. We have studied the molecular evolution of these gene families in the genomes of 48 phylogenetically diverse birds and their expression in the scales and feathers of the ...
