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.
Keywords: millimeter electromagnetic wave, DNA, solution, irradiation
At present, the millimeter electromagnetic waves (MMEW) of a nonthermal intensity have been
successfully used in various fields, in clinical medicine, despite the fact that the mechanisms of their
action on biological objects remain non-investigated. The numerous weak intensity MMEW effects on the
human and animal organism, as well as at the cellular level are detected [1, 2]. The availabilities both the
selective frequency-dependent effects  and the non-selective frequency-independent influences [4, 5]
are shown. However, up to now the primary targets of the perception of these waves are not uniquely
revealed. A number of studies shows that MMEW can change the volumetric properties of aqueous
solutions, in particular, to change the structuring of water [6, 7]. We recently showed  that the surface
layer of aqueous solutions does not absorb the MMEW, they penetrate into the deeper layers of liquid and
result to the dehydration of ions present in the solution, with a consequent of which the density of
The aim of present work is to study the density of water-saline solutions and the water-saline solutions
of deoxyribonucleic acids (DNA) as a function of temperature and the determination of the coefficient of
thermal expansion of irradiated of weak-energy coherent MMEW at the frequencies of 50.3 and 64.5
GHz, coinciding with the resonance frequencies of oscillations of molecular water structures .
2. MATHERIALS AND METHODS
In this work, the calf thymus DNA from Sigma and NaCl from Serva have been used. The DNA
solutions were prepared in the physiological solution (0.15 M NaCl). The water-saline solutions under
investigation were prepared one hour before the measurements. The density of samples was determined
