60Co γ-ray attenuation coefficient of barite concrete
ABSTRACT Introduction: Recently uses of medium and high energy x-rays has been increased in Iran and radiotherapy centers along with a variety of accelerators have been installed in some provinces. In the other hand there is no sufficient skill in designing and making radiotherapy treatment rooms. This study was conducted to evaluate the efficacy of different m...
متن کاملChemical corrosion on gamma-ray attenuation properties of barite concrete
osting by E Abstract The variation of photon attenuation coefficient on the chemical media has been investigated. For this purposes the linear attenuations of barite concrete have been measured at 662, 1773 and 1332 keV before leaving the chemical media and following a 6 month period. The linear attenuation coefficients have been measured using gamma spectrometer that contains a NaI(Tl) detecto...

متن کاملApplication of FLUKA code to gamma-ray attenuation, energy deposition and dose calculations
Background: In radiation therapy, water is the phantom material of choice, both for reference and for relative dosimetry measurements. Solid phantoms, however, are more useful for routine measurements because they tend to be more robust and easier to set up than water phantoms. Materials and Methods: FLUKA input data cards have been arranged in sequential order. A simple cylindrical geometry wi...
متن کاملMeasurement of the x-ray mass attenuation coefficient of copper using 8.85–20 keV synchrotron radiation
This work presents the x-ray extended range technique for measuring x-ray mass attenuation coefficients. This technique includes the use of multiple foil attenuators at each energy investigated, allowing independent tests of detector linearity and of the harmonic contributions to the monochromated synchrotron beam. Measurements over a wide energy range allow the uncertainty of local foil thickn...
