characterization of a new prepared li2b4o7: mn dosimeter for γ- irradiation high-dose dosimetry

Study of Thermal Treatment and Kinetic Parameters of Prepared Li2B4O7: Cu Thermoluminescence Dosimeter

Onyx Samples Characterization by Osl Technique for High-dose Dosimetry

Onyx samples were studied in this work to verify their dosimetric properties. The Onyx stone is considered nobler than marble. At IPEN, the radiation metrology group has studied new materials for application in highdose dosimetry. The Onyx samples were exposed using a Gamma-Cell 220 system ( 60 Co), for doses of 50 Gy up to 300 kGy. The lower detection doses, the reproducibility of the OSL resp...

Dimethyl sulfoxide, diethyl fumarate solution for high dose dosimetry

Background: Dosimetry is a fundamental part of the radiation processing industry. Aqueous inorganic dosimeters have been used for gamma radiation dosimetry such as standard ferrous sulfate dosimeter. The purpose of this study was to investigate the effect of gamma radiation on the diethyl fumarate DEF in dimethyl sulfoxide DMSO solution and its possible use in chemical dosimetry. Materials and ...

کاتالیزورهای co-fe-resol/sio2و fe-mn-resol/sio2 با استفاده از روش ساده و ارزان قیمت همرسوبی تهیه شدند. از رزین پلیمری resol در فرآیند تهیه کاتالیزور استفاده شد.

Synthesis and Characterization of Co-Mn Nanocatalyst Prepared by Thermal Decomposition for Fischer-Tropsch Reaction

Nano-structure of Co–Mn spinel oxide was prepared by thermal decomposition method using [Co(NH3)4CO3]MnO4 as the precursor. The properties of the synthesized material were characterized by X-Ray Diffraction (XRD), Brunauer-Emmett-Teller (BET), Transmission Electron Microscopy (TEM), surface area measurements, Energy-Dispersive X-ray (EDX) spectroscopy analys...

Commercial Window Glass Tested as Possible High Dose Dosimeter. Electron and Gamma Irradiation

The use of commercial window glass as possible high dose routine dosimeter has been investigated. Glass samples have been irradiated with doses in the range of 1–50 kGy using 60Co γ source, 4 MeV and 12 MeV electron accelerators. The samples were given a post irradiation thermal treatment (150 oC for 20 min) in order to improve the post irradiation stability of the measured specific optical abs...
