The response of potassium nitrate for high-dose radiation dosimetry

Dosimetry Characterization of Unknown Dye Polyvinyl Alcohol Films

“…From the stock solution, different concentrations of the dye such as C 1 =0.019/L, C 2 =0.029g/L and C 3 =0.039g/L were prepared at different pH values. In dosimetric studies, those dye dosimeters are considered to be satisfactory which show a linear relationship between the concentrations (C) of the dye in the solutions and absorbance (A) measured at the primary absorption peak maxima that is actually verification of Beer's Law [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. For irradiation, the dye solutions were placed in 5 ml glass ampoules having internal diameter 1.03 cm and thickness 0.18 cm with fit in ground stoppers.…”

“…The present study dealt to find a new dye dosimeter of its type. Radiation doses are generally measurable with linear response, over absorbed dose ranges between 1 and 10 4 Gy, depending on the initial dye concentration, the pH and the presence of additives as alcohols, buffers and inorganic salts [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. This dye is relatively a cheap dye.…”

Direct visualization of radiation-induced transformations at alkali halide–air interfaces

“…Reactions induced by ionizing radiation at material interfaces are important in many fields including atmospheric chemistry 1 – 3 , nuclear reactor material design, radioactive waste repositories 4 – 6 , dosimetry 7 , medical devices 8 , 9 , and space science engineering 10 . Fundamental understanding of these systems often benefits from direct detailed observations under in situ irradiation conditions in real-time to be able to infer impacts over larger spatial and temporal scales 9 , 11 .…”
