摘要: Abstract This paper has been focused on the a detail study non-ionizing and ionizing electromagnetic (EM) shielding features build-up factors of reinforced with ferrochrome (FeCr) composites. The non-inozing performance quantities composites have determined in frequency range between 12.4 18.0 GHz. Also, experimental mass attenuation coefficients (MAC) estimated using gamma spectrometer various radioactive point, compared to those theoretical simulation (MCNPX) results. With help obtained linear coefficients, several quantities, i.e., effective atomic number (Zeff), half value layer (HVL), mean free path (MFP) discussed. In addition, buildup (EBF EABF) values utilizing G-P fitting method. results showed that composite encoded FeCr(15%) is superior properties among investigated samples.
