Thermoluminescent Detectors for Neutron Dosimetry at High Altitudes
At high altitudes in the Earth’s atmosphere cosmic-ray induced neutrons become the dominant contributors to the biologically relevant dose equivalent. Depending on the geomagnetic latitude and the solar activity cycle, neutron dose onboard aircraft amounts to about 50 to 70 % of the overall dose equivalent. Neutron detection in complexly mixed radiation environments by means of active, i.e. pow...
متن کاملPerformance of thermoluminescent materials for high dose dosimetry
Cases involving high-doses of ionizing radiation are becoming increasingly common.The objective of this work was to characterize thermoluminescent materials for the dosimetry of workers exposed to high doses. Samples of TLD-200, TLD-400 and TLD-800 pellets from Thermo Electron Corporation were studied in gamma high-doses. Dose-response curves were obtained for doses between 100 mGy and 100 Gy. ...
متن کاملAmmonium dithionate- a new material for highly sensitive EPR dosimetry.
Polycrystalline ammonium dithionate has been examined for its radiation response in the low dose range (<5Gy) using EPR technique. The SO(3)(-) radical ion was detected as a single EPR line with a peak-to-peak derivative width of ca. 0.44mT in irradiated samples and its intensity was found to vary linearly with dose. At equal and moderate settings of microwave power and modulation amplitude amm...
متن کاملJordanian Zeolitic Tuff as a Raw Material for the Preparation of Substrates Used for Plant Growth
One of the problems faced in front of industry for potting media is limited amount of quality row materials (mainly peat) for unlimited production of quality substrates in the future. The using of natural minerals for production of substrates or as amendments for existing substrates is possible solution for this problem. The natural zeolites with their specific properties – high CEC, high conte...
متن کاملPercentage depth dose evaluation in heterogeneous media using thermoluminescent dosimetry
The purpose of this study is to investigate the influence of lung heterogeneity inside a soft tissue phantom on percentage depth dose (PDD). PDD curves were obtained experimentally using LiF:Mg,Ti (TLD-100) thermoluminescent detectors and applying Eclipse treatment planning system algorithms Batho, modified Batho (M-Batho or BMod), equivalent TAR (E-TAR or EQTAR), and anisotropic analytical alg...
