Radio-protective properties of some sunblock agents against ionizing radiation

When the human exposure to nuclear radiation such as gamma ray, neutrons or charged particles (protons and alpha) it may cause the menacing consequences of skin organ. The devastating effects of nuclear radiation pose a need radioprotective for protecting the skin organ and to avoid the deadly related to these radiations. The sunblock agents samples: Padimate O (SB1), Homosalate (SB2), Dioxybenzone (SB3) Sulisobenzone (SB4), titanium dioxide (SB5) and zinc oxide (SB6) have been studied in terms of mass attenuation coefficient, effective atomic number, buildup factors, fast neutron removal cross section and proton, alpha and electron mass stopping power. The results showed that the ZnO sunblock agent (SB6) has better shielding properties followed by TiO2 sunblock agent (SB5). This study could be very useful to develop novel pharmacological compounds used in radioprotection, medical diagnostics, and radiation therapy.
