Doppler broadening of energy spectra in Compton cameras

C. E. Ordonez; A. Bolozdynya; W. Chang 1997 IEEE Nuclear Science Symposium Conference Record, 1997

Compton cameras utilize the Compton effect to achieve directional localization of gamma rays. The accuracy of the localization depends, in part, on the uncertainties in the measurement of energies. These uncertainties have conventionally been assumed to be due to the effects of finite detector energy resolution alone. There is another source of energy uncertainty that none of the Compton cameras ...


Radiation Effects in LDD MOS Devices

Richard L. Woodruff; James R. Adams IEEE Transactions on Nuclear Science, 1987

The purpose of this work is to investigate the response of lightly doped drain (LDD) n-channel transistors to ionizing radiation. Transistors were fabricated with conventional (non-LDD) and lightly doped drain (LDD) structures using both standard (non-hardened) and radiation hardened gate oxides. Characterization of the transistors began with a correlation of the total-dose effects due to 10 keV x-rays and Co-60 ...

Carmen Silvia; Oprina Romul Mircea Margineanu; Otilia Cangea 2017 9th IEEE International Conference on Intelligent Data Acquisition and Advanced Computing Systems: Technology and Applications (IDAACS), 2017

Nowadays modern technology extensively uses radiation generators and radioactive sources, potentially dangerous both to human health and to the environment. In this context, there is a permanent request for high standards regarding safety and control. The paper presents a remote control data system for in-situ γ-radiation measurements that has to ensure minimal measurements impact and a feasible solution for data ...

A two-dimensional gas-based neutron detector system that can be operated under high-pressure was developed, and an irradiation experiment was performed using a Cf-252 neutron source. The signals from neutrons clearly observed and can be discriminated from background signals such as gamma-ray and electrical noises. The flat-field image showed good homogeneity and an average gain spread of approximately 7.7%. The system ...


Generation of 137Cs surface distribution maps using dense measurement transects of a towed gamma-ray spectrometer

Kosuke Murata; Blair Thornton; Kazunori Nagano; Seiki Ohnishi OCEANS 2015 - MTS/IEEE Washington, 2015

In this paper, we describe a method to generate surface distribution maps of seafloor 137Cs levels. The method interpolates the measurements of a towed gamma-ray spectrometer, which are made along intersecting line transects, by modeling the spatial variations between each observation. Since it is known that sediment type has an influence on the distribution of 137Cs, the proposed method aims ...

  • Detection and Estimation of Radiological Sources

    This chapter considers several inferential problems regarding radiological sources, including estimation of point and distributed sources using a collection of static observers and source search and estimation using mobile observers. It presents the detection and localization of radiological materials that emit gamma rays, the highly penetrating electromagnetic radiations that can travel large distances through air. The chapter devotes to batch estimation of point radiological sources using measurements from a fixed network of sensors. The Bayesian approach to inference assumes that the unknown parameter of interest is a random variable. In this framework, inferential procedures are based on the posterior distribution, that is, the distribution of the parameter conditional on the observations. Bayesian estimation was favored because of the possibility of developing accurate and computationally efficient approximations of optimal Bayesian estimators for large dimensional parameters. The Renyi divergence is only one of a number of candidates for measuring the difference between two distributions.

  • Fundamentals of Electrical Discharges

    Natural phenomena, such as gamma rays produced by radioactive decay processes in the soil and cosmic radiation originating from solar flares and other galactic objects, can ionize the air molecules. This chapter first discusses ionization and deionization processes in gases. This is followed by a discussion on ionization and attachment coefficients. Two typical breakdown mechanisms occur in gases, each of them operating under specifically favorable conditions: Townsend's mechanism and the streamer mechanism. Corona discharges in air can burn on the overstressed zones of hot electrodes. This kind of discharge occupies a short layer, attached to the energized conductor. When a conductor is in corona, then the electric field on the surface is somehow influenced by the surrounding ion space charge. Kaptzov's hypothesis (KH) relates to the assumption that the space charge emitted into the interelectrode gap is in amounts that hold the surface field at the onset level.
