[Analysis of temperature and radiation-induced effects in model and natural biomembranes using UV-spectroscopy method].
Effects of low-dose gamma-irradiation (up to 1 R) upon UV absorption spectra of water dispersions of egg yolk lecithin (1:1) and samples of rat liver homogenate were studied. Clearly detectable changes could be observed in the 200-220 nm range already under dose loads of several mGy. Radiation sensitivity was shown to be essentially temperature dependent, being the highest at physiological temperatures.
