background: the purpose of this study is to fabricate inexpensive in-house low cost homogeneous and heterogeneous human equivalent thorax phantom and assess the dose accuracy of the treatment planning systems (tps) calculated values for different lung treatment dosimetery. it is compared with thermoluminescent dosimeter (tld) measurement. materials and methods: homogeneous and heterogeneous tho...
background: the purpose of this study was to investigate the various gantry angle and ssd dependencies of tld and mosfet dosimeters. materials and methods: lif (mg) tld and mosfet were used in this study. dosimeter systems were calibrated and then irradiated at various gantry angle and ssd by applying 6 mv photon energy. results: based on the results, mosfet changes were found to be in 2% range...
The Domain Name System (DNS) plays a central role in the Internet. It allows the translation of human-readable domain names to (alpha-) numeric IP addresses in a fast and reliable manner. However, domain names not only allow Internet users to access benign services on the Internet but are used by hackers and other criminals as well, for example to host phishing campaigns, to distribute malware,...
Background: The accurate results of the individual doses in personal dosimety which are reported by the service providers in personal dosimetry are very important. There are national / international criteria for acceptable dosimetry system performance.Objective: In this research, the sources of uncertainties are identified, measured and calculated in a personal dosimetry system by TLD.Method: T...
normal 0 false false false en-us x-none fa background: the angular dependency of response for tld cards may cause deviation from its true value on the results of environmental dosimetry, since tlds may be exposed to radiation at different angles of incidence from the surrounding area. objective: a 3d setting of tld cards has been calibrated isotropically in a standard radiation field to eval...
In the present work, twelve inorganic thermoluminescence dosimeteric (TLD) materials doped with some rare earth elements (LiF:Sm, LiBaP 2 O 7 :Eu, CaCO 3 CaSO 4 :Dy, SrSO :Sm, CdSO BaSO Li B MgB :Gd, Al MgAl :Ce and LiCaAlF 6 :Eu) three organic TLD (C H NO , C 8 BaO ) were selected for comparative analysis on basis of different photon sensing parameters. About nine parameters viz. mass attenuat...
The possible defect structure of peak 1 of LiF:Mg,Ti (TLD-100) was studied in the present work after different pre-irradiation heat treatments between 80◦C and 150◦C using the computer glow curve deconvolution (CGCD) method. It was shown that the defect structure of peak 1 is based on colloid centers, Ti-3O2 -mixed centers and U1-centers.
Specific Language Impairment (SLI) is a heritable neurodevelopmental disorder diagnosed when a child has difficulties learning to produce and/or understand speech for no apparent reason (Bishop et al., 2012). The verbal difficulties of children with SLI have been largely documented, and a growing number of studies suggest that these children may also have difficulties in processing non-verbal c...
