Cost, weightiness, vacuum, and absorption power of the matters applied for radiological preservation are significant points which challenge scientists and researchers to preparation and improve suitable γ-S materials. A perfect γ-S is one which can absorb, attenuate, or prevent the ultimate part of incident γ-radiation. The major purpose of this study is to evaluation the effect of silver nanoparticles (AgNPs) additions on the γ-S characteristics of polyvinyl alcohol PVA, polyacrylamide PAAm and polyacrylic acid PAA polymeric blend (PB). In the current research, PVA/PAAm/PAA (70:20:10) wt./wt.% matrix PB with 0, 0.03, 0.06 and 0.08 wt% of AgNPs were synthesized via Petri dish casting technique as a polymer nanocomposites (PNCs). The specimen were categorized as h0,h1,h2 and h3 depending on the addition of AgNPs. Crystal structure involves X-ray diffraction (X-ray), the Fourier transformation infrared spectrum (FT-IR), ultraviolet-visible light spectrum (UV-V) and optical microscopy (OPM) were studied. The coefficients of attenuation were also computed utilizing caesium (Cs137) source. Results showed which increasing of AgNPs from 0% to 0.08% leads to increasing in the attenuation coefficient values and decreasing the ratio of radiation counts (N/Nₒ), also 0.08% of AgNPs loaded is the essential optimum consist of this additive. The γ-S properties conducted using γ-rays has explained which PNCs with 8% of AgNPs and only 0.090 cm thickness, can attenuate 80% of the γ- ray.
