Abstract

The kinetics of the formation of color centers in solid potassium picrate in a γ-radiation field was studied. Optical spectra in potassium picrate were studied for the first time. The transmission spectra of irradiated crystals of potassium picrate displayed peaks at 515 (2,6-dinitro-para-quinone) and 630 nm (a picric acid-derived radical containing the nitrite group), with the intensity increasing with an increase in the absorbed dose. The potassium picrate radiolysis scheme is discussed.
