Portable personnel monitor which is collapsible for transporting and storage

TLDR
In this paper, a portable personnel monitor that is easily transported, set up and operated to perform radiological contamination testing of personnel is provided by a collapsible frame containing scintillation detectors.
Abstract
A portable personnel monitor that is easily transported, set up and operated to perform radiological contamination testing of personnel is provided by a collapsible frame containing scintillation detectors. The frame has hinged columns as side members and a top member which is releasably connected with electrical and mechanical connecting and alignment devices to the columns. A signal analyzer unit is attached to one column via a T-slot and is connected to the scintillator detectors via a coaxial cable. A base plate having upstanding posts supports the frame rigidly in an upright position and is releasably connected to the columns by push/pull pins. The frame defines a passage which is of sufficinet height so that an adult human subject can pass through the radiation sensitivity field defined by the detectors. For transporting the monitor, the top frame member is unplugged and released; the signal analyzer unit is detached from the column; the columns are detached from the base and folded over into compact size. The collapsed unit is stored in suitcase size containers which are readily stowable or portable. All parts of the monitor are self-contained so that the monitor can be set up without tools and rapidly put into use.

Rapidly relocatable modular cargo container scanner

TL;DR: An X-ray cargo inspection system and method is described in this paper, where a lead-in conveyor on a first trailer receives a cargo container for inspection, and an inspection module disposed on a second trailer then scans the container with penetrating radiation, detects penetrating radiation that has interacted with the cargo container, and produces an inspection signal.

Nuclear and pressure sensitive line/perimeter detection system

TL;DR: In this paper, a system for simultaneously detecting nuclear radiation and pressure combines light signals from a radiation sensitive scintillating optical fiber with light signal from a pressure sensitive optical fiber, which is coupled to a light transmitting optical fiber for long distance light transmission to a detector unit such as a photomultiplier tube.
