Energy Absorption and Exposure Buildup Factors of Essential Amino Acids
The effective atomic number and effective electron density in amino acids are of significant interest due to their use in various applications. The energy absorption buildup factors, exposure buildup factors, effective atomic numbers, and electron densities of essential amino acids such as Leucine (C6H13NO2), Lysine (C6H14N2O2), Methionine (C5H11NO2S), Phenylalanine (C9H11NO2), Threonine (C4H9N...
متن کاملA Comprehensive Study on Energy Absorption and Exposure Buildup Factors for some Soils and Ceramic Materials
Abstract: Study of gamma ray energy absorption (EABF) and exposure buildup factors (EBF) for some essential soils, ceramic materials in the energy region 0.015-15 MeV up to a penetration depth of 40 mfp (mean free path). To calculate both EABF and EBF, five parameter geometric progressions (G-P) fitting approximation has been used. Variation of EABF and EBF with incident photon energy, penetrat...
متن کاملEnergy Absorption Buildup factor for some Oxide Glasses: Penetration Depth, Photon Energy and Effective Atomic Number Dependence
In present investigation, the study of gamma ray Energy absorption buildup factors (EABF) for three oxide glasses, viz. CaO-Al2O3, Na2O-SiO2, and Na2O-Al2O3-SiO2. The computations were done by ANSI/ANS-6.4.3 library and interpolation method using the Geometric Progression fitting formula for the energy range from 0.015 to 15 MeV, up to penetration depths 40 mfp (mean free path). The buildup fac...
متن کاملa case study of energy absorption buildup factors in some human bones for gamma energies 30 kev to 1.5 mev
human body consists of some tissues among which bone is one of the important living and growing tissue . in this research, energy absorption buildup factor (eabf) values of 27 types of bone have been computed for photon energy 0.03 to 1.5 mev up to 40 mean free path (40mfp) penetration depths. the inner bone tissue, spongiosa and male sternum had the largest values of eabf in low photon energie...
متن کاملCalculating Weighting Factors for Mixing Megavoltage Photon Beams to Achieve Desirable Dose Distribution in Radiotherapy
Background: In radiotherapy, low-energy photon beams are better adapted to the treated volume, and the use of high-energy beams can reduce hot spots in the radiation therapy. Therefore, mixing low and high energies with different ratios can control the rate of hotspots, as well as the dose distribution of the target volume.Material and Methods: The percentage depth doses (PDDs) were calculated ...
