In this paper, adipic acid crystals were grown using slow evaporation method in aqueous solution of l-alanine at room temperature. X-ray diffraction investigation shows that the crystal belongs to P21/n space group. EDAX study confirms the occurrence of elements in the crystal. The crystal is thermally stable up to 124 °C. Further, the grown crystals were exposed to Co-60 gamma radiations with different doses of 1 Mrad, 3 Mrad, and 5 Mrad at normal room temperature. After gamma irradiation, a small change in the intensity and a slight shift in the Powder X-Ray Diffraction (PXRD) peaks were seen. UV–visible analysis reveals an increase in reflectance after gamma irradiation. Increase in dielectric constant, dielectric loss, and AC conductivity was observed by dielectric studies. Second Harmonic Generation (SHG) efficiency of the crystal is 0.42 times that of the standard Potassium Dihydrogen Phosphate (KDP) crystal and is increased moderately up to the gamma irradiation dosage of 3 Mrad.
