Влияние частоты электромагнитного излучения дециметрового диапазона на процесс митоза в растительных тканях

Влияние частоты электромагнитного излучения дециметрового диапазона на процесс митоза в растительных тканях

Abstract

Вопрос опасности для здоровья человека микроволнового излучения (300 МГц – 300 ГГц) является одним из актуальных вопросов на сегодняшний день. Данное исследование посвящено воздействию излучения частот, соответствующих частотам сотовой связи стандарта GSM и близкого к ним диапазона частот. В качестве источника излучения использована радиоизлучающая установка с постоянным сигналом, настроенная на обеспечение уровня сигнала на уровне мощности сотового телефона. В качестве тестового объекта использован лук Allium cepa для оценки митотического индекса по методике allium test. Эксперимент поставлен таким образом, чтобы обеспечить облучение именно анализируемых тканей корня, максимально снизив воздействие на остальные ткани тестового объекта. Выращивание тестового объекта производилось при термостатировании опытной установки, обеспечивающем постоянную температуру во всех повторностях. Анализ полученных данных позволяет говорить о существовании нелинейной зависимости между частотой электромагнитного излучения и его митотоксическом влиянии на тестовые объекты. Значительным митотоксическим эффектом обладает излучение в диапазоне 800-930 МГц, что соответствует стандарту сотовой связи GSM 850/900.

Problems of hazard caused by electromagnetic radiation in microwave range (300 MHz – 330 GHz) is one of very actual modern problems. This investigation dedicated to effect of GSM-frequency and near range radiation on live tissue. We use special installation to provide signal of various frequencies with power level aligned to be equal to signal level of GSM-900/1800 cellular phone. As the test object we used Allium cepa to count mitotic index by allium-test method. Experiment conditions aimed to provide influence of electromagnetic radiation on examined tissue and to reduce undesired influence on other tissues of test object. Test objects growed in conditions of constant temperature, provided by thermostating of experimental installation. An experiment result indicates a non-linear dependence between radiation frequency and its toxic effect. The most significant mitotoxic effect belongs to radiation in range of 800-930 MHz, what corresponds to GSM 850/900 range.
