Gamma-radiation detector module for portal applications

摘要

The gamma-radiation module includes a housing having a box-like container and a cover for hermetically sealing a pair of cylinders within the housing. Each cylinder includes scintillation material and a photomultiplier tube on a common cylindrical axis. The hermetically sealed module may be used singly or in multiple modules in portal applications whereby gamma-radiation from a source may be detected through a gamma-radiation transparent cover on the module.
