Specific absorbed fraction of energy and relative dose in Zinc alloys

Due to the desirable corrosion characteristics and biocompatibility, Zinc alloys can be used as the biodegradable metals. In the present work we have investigated the specific absorbed fraction (SAF) of energy, energy absorption buildup factors (ABFs) and relative dose (RD) in the energy range 15 keV–15 MeV for zinc alloys of different composition such as alloy A (Cu 20 %, Ni 40 %, Zn 40 %), alloy B (Cu 30 %, Ni 35 %, Zn 35%), alloy C (Cu 40 %, Ni 30 %, Zn 30%), alloy D (Cu 50 %, Ni 25 %, Zn 25%), alloy E (Cu 60 %, Ni 20 %, Zn 20%) and alloy F (Cu 70 %, Ni 15 %, Zn 15%) up to the penetration depth (PD) of 40 mfp using GP fitting method. It is found that both SAF and RD are larger for alloy F (Cu 70 %, Ni 15 %, Zn 15%) than the other studied zinc alloys. Hence, we can conclude that the alloy F (Cu 70 %, Ni 15 %, Zn 15%) is a good absorber of X-rays, neutrons and gamma among the investigated zinc alloys. This work finds its usefulness in the radiation dosimetry and shielding of radiation. We have investigated the EABFs, SAF of energy and RD for zinc alloys. From this study, it is clear that for the alloy of composition (Cu 70 %, Ni 15 %, Zn 15%), the SAF of energy and RD is maximum among all the studied zinc alloys. From this study we can suggest that the zinc alloy of composition (Cu 70 %, Ni 15 %, Zn 15%) can be used as a good absorber of gamma rays, neutrons and X-rays
