Performance of a Portable, Electromechanically-Cooled HPGe Detector for Site Characterization
High-resolution, germanium detectors (HPGe) have long been used for radionuclide characterization of nuclear sites, both buildings and large areas, for the purpose of cleaning up the site. Several systems consisting of a detector, mobile support, collimators and software for data collection and spectrum analysis have been made by national laboratories and commercial companies. The efficacy of t...
متن کاملSensor Selection for Hand-Held Portable Gas Detectors
Hand-held portable gas detectors often may be configured to have 4, 5, or even 6 different sensors installed by the factory. The sensor selection should be made by the prospective purchaser based on the intended application of the instrument after they take possession of the device. The prospective user needs to convey to the factory such possible applications as Confined Space Entry, HazMat Re...
متن کاملDesign, Construction and Performance Evaluation of a HPGe Detector Shield
A multilayer passive shield composed of low-activity lead (Pb), copper (Cu), tin (Sn) and iron (Fe) was designed and manufactured for a coaxial HPGe detector placed at a surface laboratory for reducing background radiation and radiation dose to the personnel. The performance of the shield was evaluated and efficiency curves of the detector were plotted by using of various standard sources in di...
متن کاملMotion Estimation of a Hand-held Mine Detector
This paper presents the results of simulating position estimation from a camera-based system integrated in a hand-held mine detector. The system reports positions of the sensor head relative to a bar placed on the ground by the deminer to indicate the safe limit. Monitoring the position during sensor scanning enables image reconstruction of the captured signals. Image representation allows obje...
متن کاملDevelopment and Performance Test for a New Type of Portable Soil EC Detector
Key Laboratory of Modern Precision Agriculture System Integration Research, Ministry of Education, China Agricultural University, Beijing 100083, China. *Email: [email protected] ABSTRACT: The soil electrical conductivity (EC) refers to the capability for soil to conduct current. It is a comprehensive reflection of soil salinity and moisture. Therefore, acquiring soil EC rapidly and accurately ca...
