摘要：
The fundamental electrical noise of living cells due to thermal and current carrier fluctuations were discussed. It was shown that the levels of thermal and shot noise at cell's membrane are comparable. The ionic channels opening-closing fluctuations can substantially increase the noise level and add an excess noise. The sensitivity of a typical cell is about of 10(-8) W/m(2). The numerical modelling of electromagnetic wave propagation in multilayered tissue was used for field level determination inside the body. The radiation density inside the body at the depth of 3-5 cm was 10(-5) - 10(-6) from this level near the surface at 4500 MHz frequency, The experiments with low-level extremely low frequency amplitude-modulated radiation at 450 MHz frequency were carried out.
