The technique of an estimation of the compelled environmental risk for people health because of the influence of the total electromagnetic field (EMF) created by all fixed transmitters of all radio services and taking into account the contribution to total field intensity of electromagnetic radiations of mobile telephones is submitted. The novel probabilistic criterion of electromagnetic safety of population is used — the criterion of excess by total relative EMF intensity (including totality of quasi-stationary and stochastic components) of the maximum permissible level, with probability no more then one percent. Procedure of application of this technique at estimation of electromagnetic safety in places with intensive use of mobile phones is given.
