Abstract
Upon the completion of characterizing the Godiva-IV leakage dose in 2014 and a nuclear accident dosimeter (NAD) intercomparison exercise in 2016, the U.S. Department of Energy (DOE) Nuclear Criticality Safety Program (NCSP) supported an experimental campaign to characterize the Flattop leakage dose in 2017. Two Rotating Neutron Spectrometers (ROSPEC) and a Passive Neutron Spectrometer (PNS) were used to measure the neutron spectra. The neutron spectra were converted to neutron dose using dose conversion factors. CaF:Mn thermoluminescent dosimeters (TLDs), LiF TLDs, and radiophotoluminescence dosimeters were used to measure the photon doses. The data were documented in a report at that time but this paper reanalyzed and updated results. This work established updated reference neutron and photon doses as a function of radial distance from the center of Flattop, which will be used for future NAD intercomparison exercises.
期刊介绍:
The journal seeks to publish papers that present advances in the following areas: spontaneous and stimulated luminescence (including scintillating materials, thermoluminescence, and optically stimulated luminescence); electron spin resonance of natural and synthetic materials; the physics, design and performance of radiation measurements (including computational modelling such as electronic transport simulations); the novel basic aspects of radiation measurement in medical physics. Studies of energy-transfer phenomena, track physics and microdosimetry are also of interest to the journal.
Applications relevant to the journal, particularly where they present novel detection techniques, novel analytical approaches or novel materials, include: personal dosimetry (including dosimetric quantities, active/electronic and passive monitoring techniques for photon, neutron and charged-particle exposures); environmental dosimetry (including methodological advances and predictive models related to radon, but generally excluding local survey results of radon where the main aim is to establish the radiation risk to populations); cosmic and high-energy radiation measurements (including dosimetry, space radiation effects, and single event upsets); dosimetry-based archaeological and Quaternary dating; dosimetry-based approaches to thermochronometry; accident and retrospective dosimetry (including activation detectors), and dosimetry and measurements related to medical applications.
