چکیده
Currently, the problem of electromagnetic safety population has acquired social significance and is an urgent issue for modern development Republic Kazakhstan, as well other countries world. Environmental exposure to radiofrequency fields from mobile phones rapidly increased in last two decades this trend expected continue. Modern technologies have become a source pollution generated fields. Due increase technogenic processes their influence on Earth’s field, topic radiation living organisms been increasingly studied. All sources fields, rule, are complex that affects plants, animals, insects soil flora zone The effect emitted cell human health one most important topics research because widely used all over In many countries, cellular communication occupies special place among anthropogenic radiation. A phone small-sized transceiver operating 900/1800 MHz range, which refers damaging environmental factors. abundance Daphnia magna was investigated. Radiation effects clearly evident toxicology study with Samsung Galaxy J7 Vivo V 20 phones. During experiment, these models established, under higher than J7, but lower control group.
