Using Nonlinear Dynamics methods, in particular Higuchi’s fractal dimension that is a quantitative measure of deterministic
chaos, one can assess which person may be hyper-sensitive to electromagnetic fields used in mobile communication, pointing
out those persons who might belong to high-risk group. The same method may be used for testing of different cellular phones
models for their certification.
