Abstract:The aim of the present study is to determine effective atomic numbers ( Z ef f ) of Fe x Cu 1−x binary ferroalloys using scattering of 59.54 keV gamma photons at 130• ( x = 4.36Å −1 ) scattering angle. For this purpose, the Rayleigh ( R) and Compton ( C) scattering intensities for the given alloys were measured using a monoenergetic beam of 59.54keV gamma rays and the Rayleigh-to-Compton scattering ratio R/C was determined. Then the Z ef f values of these alloys were determined by interpolating the R/C of the material using the R/C data of adjacent elements in between the R/C of the alloys. For comparison, Z ef f s of alloys were also calculated using direct and interpolation methods in term of scattering R/C and attenuation of gamma photons. Good agreement in relative differences between Z ef f s (experimental and theoretical) was found (maximum of ≤ 3.3% for total att.-direct method) for the chosen alloys and the Rayleigh-to-Compton scattering ratio was shown to be a complementary approach to determine the effective atomic number of binary ferroalloys. In addition, a polynomial equation between the experimental R/C values and the mass attenuation coefficients of alloys was developed to estimate the mass attenuation coefficient of different materials.

“…particleboards were determined using the energy dispersive X-ray analysia (EDXA) from a scanning electron microscope (SEM). The effective number, Z eff was be calculated using the equation: ( 1 ) with a i and z i are electron fraction and atomic number of i th element in the sample while m is the experimental coefficient for biological materials and water having value of 3.4 [9]. The electron fraction of the i th element can be calculated using the equation: ( 2 ) with w i and A i are fractional weight and atomic mass of the i th element respectively.…”

“…The effective atomic number of the new phantom material has to be in good agreement with those of human tissue and water as the standard phantom material. The Zeff is calculated by Equation 5 (Tsai and Cho 1976, Duvauchelle et al 1999, Olarinoye 2011: ( 5 ) where α i and Z i are the electronic fraction and atomic number of the i th element in the composite, respectively. Also, m is an experimental coefficient, which is 3,4 for the biological substance such as tissue and wood (Tsai andCho 1976, Duvauchelle et al 1999).…”

In this study, some characteristics of Rhizophora spp. particleboards bonded with Serishoom (traditional animal-based adhesive) as a phantom material was investigated. The Rhizophora spp. particleboards were fabricated in two Serishoom adhesive treatment levels (6% and 12%) with three Rhizophora spp. particle sizes (≤ 149 µm, 149 µm -500 µm, and 500 µm -1000 µm) at 1 g.cm -3 of the target density. The internal bond strength and the dimensional stability of the Serishoom-bonded Rhizophora spp. particleboards were improved by using the smaller Rhizophora spp. particle size and the higher Serishoom adhesive treatment level. The effective atomic numbers of the Serishoom-bonded Rhizophora spp. particleboards were determineted to be 7,56 to 7,58 by an energy dispersive X-ray, which is in good agreement with those of water and breast tissue. In addition, the density distribution profiles of the fabricated Serishoom-bonded Rhizophora spp. particleboards were determined by the Kriging method with the use Surfer8 computer software, which indicated that there was good density homogeneity throughout the Serishoom-bonded Rhizophora spp. particleboards. The results showed a potential of the Serishoom-bonded Rhizophora spp. particleboard bonded with Serishoom to be used as a phantom material.
