Abstract
The temperature dependences of density (ρ) and the thermal expansion coefficient (α) of distilled water, a physiological solution and the water-saline solution of the DNA were studied upon the irradiation of solutions by the millimeter electromagnetic waves of non-thermal intensity at the frequencies of 64.5 and 50.3 GHz. It is shown that the density of non-irradiated and irradiated solutions decreases at the heating of solutions; however, there is a significant difference between the variation of the dependence of ρ(t) for irradiated and non-irradiated water-saline solutions. Computations show that the thermal expansion coefficient increases with the temperature increase for the solutions under investigation, though for the irradiated solutions the α growth occurs differently.
