A model to determine the dose rate of a planar alpha-emitting surface has been developed. The approach presented is computationally efficient mathematical using stopping range data from Stopping Ranges Ions in Matter (SRIM) software. alpha rates as function distance irradiated UO2 spent fuel surfaces were produced for benchmarking with previous modelling attempts. This method able replicate Mon...

Most investigations of the gamma-shielding abilities materials are often based on Beer-Lambert law including recent studies clay-polyethylene composites. The findings usually silent secondary radiation effects that commonly occur due to photon buildup, known as Energy Absorption Buildup Factor (EABF) and Exposure (EBF). In this work, computation EABF EBF in region energy 0.015–15 MeV at differe...

Background: 66Ga (t1/2=9.49 h, β+: 4.153 MeV, γ: 511, 834, 1039, 2752 keV) has a wide range of applications in different fields of medical sciences. Production of 66Ga became one of our main interests, according to its increasing applications in nuclear medicine, particularly in PET imaging. Materials and Methods: 66 Zn (p,n)66Ga reaction was determined as the best choice for the production of ...

Scanning-electron-beam lithography (SEBL) is the workhorse of nanoscale lithography in part because of the high brightness of the Schottky source of electrons, but also benefiting from decades of incremental innovation and engineering of apparatus around the Schottky source. Light ions are an attractive intermediary between electrons and heavy ions in terms of exposure efficiency and resolution...

in this paper, efforts are made to compare the safety of steel moment resistant frames designed according to different editions of the iranian code of practice for seismic resistant design of buildings. also, failure risk of a low and medium height frame which designed for high and low seismicity regions according to three editions of the code are evaluated. first, the testing cases were design...

KY(WO4)2 represents an outstanding host material for fabricating both bulk and waveguide lasers, when doped with different rare-earth elements. Ion implantation can be regarded as a universal tool for fabricating low-loss waveguide structures in optically active oxide materials [1]. In this contribution we report, for the first time to our knowledge, results obtained when implanting light ions,...
