Production of Tc-99m from naturally occurring molybdenum absent uranium

K. Pagdon; C. Gentile; A. Cohen; G. Ascione; G. Baker 2011 IEEE/NPSS 24th Symposium on Fusion Engineering, 2011

Technetium-99m (Tc-99m) is the world's most widely used medical isotope. Current production methods involve the irradiation of highly enriched uranium (HEU) and low enriched uranium (LEU) targets in nuclear reactors. Molybdenum-99 (Mo-99) is then extracted from these targets, which decays to Tc-99m. Currently, this process is centralized, as there are very few companies that manufacture Mo-99. In an effort to ...


GEANT4 simulations and experimental measurements of absolute source activity using modified sum-peak method

M. Dhibar; I. Mazumdar; G. Anil Kumar 2015 IEEE Nuclear Science Symposium and Medical Imaging Conference (NSS/MIC), 2015

In the present work, we have made Monte Carlo simulations of the response of 1" × 1" LaCb(Ce) and 1" × 1" LaBn(Ce) scintillation detectors using the radioactive sources emitting two gamma rays in cascade, namely, 60Co, 94Nb, 46Sc and 24Na for different values of source-detector separation. These simulations were done using GEANT4 toolkit that include radioactive decay module and ...


Design Optimization of Liquid Scintillation Cosmic Ray Veto Detector with BBQ Shifter

H. W. Kruse; S. S. Egdorf; D. F. Simmons IEEE Transactions on Nuclear Science, 1982

Certain design characteristics of a liquid scintillator detector for charged cosmic particles, have been studied. These include evaluation of scintillator emission spectra, absorption in various thicknesses of BBQ shifter bars and effective transmission in long lengths of BBQ acrylic. For our BBQ sample, 12.5 mm thick with semicircular shape, the shifted light was transmitted with 2.0 m absorption length.


Implications of lightning emissions for terrestrial gamma-ray flashes and associated lightning discharges

Gaopeng Lu; Steven A. Cummer 2014 International Conference on Lightning Protection (ICLP), 2014

Remote sensing of broadband (<;1 Hz to 300 kHz) lightning signals related to terrestrial gamma-ray flashes (TGFs) indicates that gamma-rays in TGFs are typically produced during a slow process that creates a considerable charge moment change within a few milliseconds. This slow process is usually punctuated by one or more fast discharges one of which is involved in gamma- ray ...


Assessment of the operational dose rate in polymer insulators in the test cell of the IFMIF neutron source

A. Klix; F. Arbeiter; U. Fischer; V. Heinzel; K. Kondo; A. Serikov 2011 IEEE/NPSS 24th Symposium on Fusion Engineering, 2011

Insulators for electrical connections of the test modules in the test cell of the IFMIF neutron source will be exposed to intense ionizing radiation even if they are located away from the neutron source. Aim of this work was to check whether radiation-hard polymers such as polyimide would be sufficiently long- lasting in such an environment. The calculations presented here ...

  • 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.
