Not have any impact of electromagnetic radiation on the human body

In fact, not just any electromagnetic radiation on the human body has an impact, as long as the intensity is not, there is air circuit breaker to the human body. As for the market to sell the products anti-electromagnetic radiation, mostly without any effect, we should not be deceived. Remember, electromagnetic shielding method only with circuit breakers or metal plate, or on the use of thick concrete or soil to absorb. If you can not shield strength of strong Circuit breaker waves, so you will not be affected only way to stay away from the radiation source, because of the intensity of electromagnetic waves and is inversely proportional to the square of the distance, that is twice the distance of the original, the intensity is reduced to the original quarter.
