Abstract

In the care of people injured with wounds with incorporated radioactive material, the basic information is collected, using appropriate detectors, following procedures established in first aid protocol. The reliability of the data collected for medical treatment depends greatly on the metrological performance of the equipment, the experimental set up and the scenario of the occurrence of the accident. The methodology to evaluate the performance of the detectors use the comparison of the attenuation coefficient value of each radionuclide obtained by the attenuation curve of tissue-equivalent material to the theoretical value established by NIST in each experimental set up. The good performance was defined when the difference between the experimental and theoretical value is close to zero. The experimental set ups were chosen according to the types of possible measurements performed in the various scenarios of the radiological accident. The detectors used were Personal Radiation Dosimeter, IdentiFINDER2, Cadmium Telluride and Hyper Pure Germanium. Furthermore, the results for ²⁴¹Am showed better performance with HPGe and IdentiFINDER2 shielded. For the ⁶⁰Co the best performance occurred with the shielded and collimated IdentiFINDER2. For the ¹³⁷Cs, the HPGe detector presented the best performance.

Air-kerma strength determination of a new directional {sup 103}Pd source

Journal Article Aima, Manik ; Reed, Joshua L. ; DeWerd, Larry A. ; ... - Medical Physics

Purpose: A new directional {sup 103}Pd planar source array called a CivaSheet™ has been developed by CivaTech Oncology, Inc., for potential use in low-dose-rate (LDR) brachytherapy treatments. The array consists of multiple individual polymer capsules called CivaDots, containing {sup 103}Pd and a gold shield that attenuates the radiation on one side, thus defining a hot and cold side. This novel source requires new methods to establish a source strength metric. The presence of gold material in such close proximity to the active {sup 103}Pd region causes the source spectrum to be significantly different than the energy spectra of seeds normallymore »« less

Performance Evaluation of Spectroscopic Detectors for LEU Hold-up Measurements

Technical Report Venkataraman, Ramkumar ; Nutter, Greg ; McElroy, Robert Dennis

The hold-up measurement of low-enriched uranium materials may require use of alternate detector types relative to the measurement of highly enriched uranium. This is in part due to the difference in process scale (i.e., the components are generally larger for low-enriched uranium systems), but also because the characteristic gamma-ray lines from ²³⁵U used for assay of highly enriched uranium will be present at a much reduced intensity (on a per gram of uranium basis) at lower enrichments. Researchers at Oak Ridge National Laboratory examined the performance of several standard detector types, e.g., NaI(Tl), LaBr3(Ce), and HPGe, to select a suitablemore »« less

Physicochemical, Antimicrobial and Cytotoxic Characteristics of Corn Starch Film Containing Propolis for Wound Dressing

Journal Article Eskandarinia, Asghar ; Rafienia, Mohammad ; Navid, Sepehr ; ... - Journal of Polymers and the Environment

Modern dressings increase the rate of wound healing rather than just covering them. Dressing can protect the injured skin and keep it appropriately moist to speed up the healing process. In this study, the ethanolic extract of propolis loaded with corn starch was successfully prepared using solvent casting. Characterizations of the samples performed in respect to their mechanical properties were examined by scanning electron microscopy, contact angle, and attenuated total reflectance—fourier transform infrared spectroscopy, as well as antimicrobial capacities. The MTT assay using fibroblast cells showed the cell viability of corn starch in the ethanolic extract of propolis wound dressing.more »« less

Calibration of a {sup 241}Am wound-monitoring system using Monte Carlo techniques

Journal Article Hickman, D P ; Kruchten, D A ; Fisher, S K - Health Physics

Monte Carlo techniques have been used to establish calibration factors and to predict gamma spectra for well-defined measurements. These techniques are routinely used to predict shielding requirements and criticality specifications. The Lawrence Livermore National Laboratory is researching the feasibility of using Monte Carlo techniques to establish calibration factors for in vivo measurement systems. A pilot study was conducted to demonstrate the use of the Monte Carlo technique to calibrate in vivo measurement systems, to predict the efficiency of a wound measurement system and compare the predicted efficiency with the measured efficiency, and to investigate the effects of the source geometrymore »« less

Criticality Accident Alarm System Shielding Benchmark: Integral Experiment Request 498, Critical Engineering Decision 1 Report

Technical Report Cumberland, Riley ; Celik, Cihangir ; Bowen, Douglas

This report supports Critical/Subcritical Experiment Decision 1 (CED-1) for Integral Experiment Request (IER) 498, a shielding benchmark produced using the Godiva IV critical assembly at the National Critical Experiments Research Center (NCERC). Shielding benchmarks are datasets collected to provide a comparison for computer models that simulate the effect of shielding on radiation transmission from a source to a detector. The purpose of a CED-1 report is to produce a conceptual design for an integral experiment and to identify the long lead-time items. The design presented in this report favors certain detailed design options such as material selections. However, alternative optionsmore »« less
