In this paper, first, a methodological principle trial for the quantitative evaluation of the correlative and/or cumulative effect on indoor high-technology pollution has been proposed under an absolutely inseparable relationship between utility and risk at the same time and in the same ring. Then, the effectiveness of the proposed method is partly confirmed through some principle experiment between sound (served for utility) and leaked magnetic field (served for risk) especially before and after attachment of a magnetic oscillator called Tecno AO (CE mark, ISO sanction).

Оценка взаимного воздействия акустического и магнитного полей вблизи монитора
Рассмотрены методологические основы испытаний по количественной оценке взаимозависимого и/или совокупного воздействия на загрязнение среды в помещениях, связанного с использованием высокотехнологичного оборудования. Методика базируется на соотношении пользы от использования оборудования и риска для здоровья в данном месте и в данное время. Эффективность предлагаемого метода подтверждена экспериментами, целью которых было исследование влияние двух факторов, воздействующих на человека вблизи компьютера: звука и магнитного поля. Оценено также положительное действие устройства (Tecno AO), снижающего магнитное поле.
