The study of radiation absorption in material is an important subject to protect living creatures and environment from harmful effect of radiation. The degree to which gamma radiation is attenuated is dependent upon the energy of the incident gamma radiation, the thickness of the shielding, the atomic number and density of the elements in the shielding material. In this respect, this study pres...

We used synchrotron x rays to measure the x-ray mass attenuation coefficients of gold at nine energies from 38 to 50 keV with accuracies of 0.1%. Our results are much more accurate than previous measurements in this energy range. A comparison of our measurements with calculated mass attenuation coefficients shows that our measurements fall almost exactly midway between the XCOM and FFAST calcul...

The variation in mass attenuation coefficient μ for total and partial photon interaction processes for three different oxide glasses (65CaO-35Al2O3(OG1) , 20Na2O-80SiO2(OG2), and 20Na2O-5Al2O3-75SiO2 (OG3)), in the incident energy range from 10 keV to 100 GeV has been studied using software package XCOM and the effect of chemical composition on the values of μ is also interpreted graphically. M...

When released from an initial, static, forward lean angle and instructed to recover with a single step, some older adults are able to meet the task requirements, whereas others either stumble or fall. The purpose of the present study was to use the concept of margin of stability (MoS) to investigate balance recovery responses in the anterior-posterior direction exhibited by older single stepper...

The biological tissue has been mimicked and replaced by other materials, which have shown certain radiological similarity determined by attenuation coefficient (μ), density and atomic number. Specifically, in molecular imaging and radiation therapy have been developed multifunctional radiopharmaceuticals which contain beta/gamma and/or light emitters to chronic degenerative diseases treatment. ...

The web changes commercial activities such as information gathering, shopping, trading, collaboration, and distribution to which companies need to adapt their strategies. The importance of information and communication technology (ICT), especially of the internet in the travel and tourism industry has increased tremendously over the past few years. The travel and tourism area is one of those in...

Mass attenuation coefficients and partial photon interactions have been calculated theoretically at incident photon energy 1 Kev to 100 GeV for garnet series of gemstones (Grosaularite (GS1), Pyrope(GS2), Spessarlite(GS3), Almandine(GS4), Uvarovite(GS5) and Androdite(GS6) using XCOM software [1]. The values of these parameters have been found to change significantly with incident photon energy ...
