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 : in spite of clinically useful photon and electron beams, high energy linacs produce secondary particles such as neutrons (photo-neutron production). neutrons have important roles during treatment with high energy photons in terms of protection and dose escalation. in this project, neutron dose equivalent of 18 mv varian accelerators is calculated by tld600 and tld700. materials and...

We consider reduced quantum electrodynamics (RQED$_{d_\gamma,d_e}$) a model describing fermions in $d_e$-dimensional space-time and interacting via the exchange of massless bosons $d_\gamma$-dimensions ($d_e \leq d_\gamma$). compute two-loop mass anomalous dimension, $\gamma_m$, general RQED$_{4,d_e}$ with applications to RQED$_{4,3}$ QED$_4$. then proceed on studying dynamical (parity-even) fe...

introduction: active personal dosimeters (apds) are well accepted as useful and reliable instruments for individual dosimetry measurements. apds have many advantages compared with passive dosimeters for individual external radiation dose assessments. in routine monitoring, occupational exposure is carried out for verification and demonstration of compliance with the regulatory dose limits. so, ...
