This article tackles the problem of primary reception of millimeter waves by live systems. It also discusses the physical mechanisms of low-intensity millimeter-wave effect on live systems. It is postulated that water molecules of the skin can be the primary molecular receptors that transfer the energy of external radiation to primary physiological targets in the exposure site (a "water-primary target" model). The effect of solute molecules on the absorption of millimeter-wave radiation (l = 2, 5.84, and 7.12 mm) by aqueous solutions was studied on a-amino acids. Various mechanisms are outlined of intermolecular interaction of a-amino acids in aqueous solutions, such as the raised absorption of water molecules in solute hydration shells (negative hydration) and the decreased absorption of water molecules in solute hydration shells (positive hydrophilic and hydrophobic hydration).
