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.read more

Methods and apparatus for improved gamma spectra generation
Steve Beer,Dan Inbar +1 more
TL;DR: In this article, a method of improving energy determination of a Gamma event which interacts with a segmented scintillation detector is proposed, based on identifying radiation events detected by a detector that are likely not to have deposited their full energy in the detector, based only on characteristics of said detected events.
