Dosimetric Aspects of Sodium Polystyrene Sulfonate (NaPSS)

By J. Saptagiri Prasad, B. Sanjeeva Rao, Sivadevuni Kalahasti

Abstract: Thermally stimulated luminescence (TSL), electron spin resonance (ESR), Fourier transform infrared spectroscopic techniques are used to study dosimetric applications of sodium polystyrene sulfonate (NaPSS). The TSL, ESR, FTIR spectra are recorded for NaPSS-exposed different amounts of gamma radiation doses. The spectra observed under different conditions suggest that the NaPSS can be used for dosimetric applications based on the condition of linear variation of physical properties against the radiation dose.

Thermally Stimulated Luminescence and Electron Spin Resonance Study of Gamma Irradiated Poly Carbonate

By B. Sanjeeva Rao, M. Papi Reddy, A. Raju, S. Kalahasti, E. Venkateshwar Rao

Abstract: Polycarbonate (PC) is an industrially important polymer. Gamma irradiation effects of PC are investigated by thermally stimulated luminescence (TSL) and electron spin resonance (ESR) techniques. The TSL spectra of irradiated PC have shown two glow peaks, around 149oC (422 K) and 165oC (438 K). The observed glow peaks are analysed by initial rise methods, Chen’s method and modified initial rise method. The trap parameters corresponding to the two glow peaks …

TSL Studies of Monovalent and Divalent Salts of Polystyrene Sulfonate

By K. Rajendraprasad, E. Venkateshwar Rao, B. Sanjeeva Rao

Abstract: AbstractThermally stimulated luminescence (TSL) spectra of monovalent and divalent salts of polystyrene sulfonate (PSS) have been recorded to study molecular relaxations and thermally induced processes. Monovalent salts [sodium polystyrene sulfonate (NaPSS) and potassium polystyrene sulfonate (KPSS)] have shown glow peak around 365 K and 369 K while divalent salts [calcium polystyrene sulfonate (CaPSS) and barium polystyrene sulfonate (BaPSS)] have exhibited two glow peaks around 345 K, 385 K (CaPSS) and …
