Radiochromic dye cyanides and the dosimetric characteristics of their dosimeters

Abstract The new methods of synthesis and purification of two radiochromic leucodyes[pararosaniline cyanide (PR-CN) and hexahydroxyethyl pararosaniline cyanide (HPR-CN)] are outlined. Structure and purity of the products have been confirmed by elementary analysis, infrared spectrometry, ultraviolet spectrometry, field desorpt mass spectrometry and thin layer chromatography. Two leucodyes have been evaluated and used in solution dosimeters, film dosimeters, optical waveguide dosimeters.
