Pink (1/f) noise is one of the most common behaviours of biosystems. Our present paper is devoted to clarify the origin of this interesting phenomenon. It is shown that the stationary random stochastic processes under self-similar conditions (as we have in living objects) generate pink noise independently of the kind and number of variables.

The specific absorption rate (SAR) from mobile telephones at horizontal and vertical positions is investigated in human adult and child heads wearing metal-rim spectacles and having metallic implants. The SAR values calculated by Finite Difference Time Domain (FTDT) method are compared to the actual ANSI/IEEE standards and to the 900/1800/2100 MHz electromagnetic radiation limits according to EU standards. Our calculation shows a maximum of the cellular SAR in the child head, which in the case of metallic implant could be as much as 100% higher than in the adult head. The averaging on 1 and 10 g tissue-masses shows SAR generally under the limit of 519/1999/EC standards. However, in the case of 2100 MHz with vertical position of the phone for adults and of the 900 MHz for children with metallic implants the ANSI/IEEE limits are exceeded.

Living objects are complex systems with various harmonized chemical, thermodynamical, and quantum-mechanical processes in aqueous electrolyte environment. We had studied the effect of curl-free magnetic vector-potential on the matrix of the living matter, on the water. The discussed theoretical considerations are in harmony with the presented simple experiments. It is shown that the vector-potential is actually an effective electro-dynamical parameter which could modify the processes in living systems.
