Abstract

PURPOSE

The increased bioactivity 'windows' of GSM 900 and 1800 MHz radiations, (Global System for Mobile telecommunications) revealed recently by us and published in this issue, manifesting themselves as a maximum decrease in the reproductive capacity of the insect Drosophila melanogaster, were examined to discover whether they depend on the intensity of radiation-fields.

METHODS

In each experiment, one group of insects were exposed to the GSM 900 or 1800 radiation at 30 or 20 cm distances, respectively, from the antenna of a mobile phone, where the bioactivity 'window' appears for each type of radiation and another group was exposed at 8 or 5 cm, respectively, behind a metal grid, shielding both microwave radiation and the extremely low frequency (ELF) electric and magnetic fields for both types of radiation in a way that radiation and field intensities were roughly equal between the two groups. Then the effect on reproductive capacity was compared between groups for each type of radiation.

RESULTS

The decrease in the reproductive capacity did not differ significantly between the two groups.

CONCLUSIONS

The bioactivity window seems to be due to the intensity of radiation-field (10 microW/cm(2), 0.6-0.7 V/m) at 30 or 20 cm from the GSM 900 or 1800 mobile phone antenna, respectively.

摘要

目的

我们最近发现并在本期发表的 GSM 900 和 1800MHz 辐射（全球移动通信系统）的生物活性“窗口”增加，表现为昆虫黑腹果蝇生殖能力的最大下降，本研究旨在探究这些“窗口”是否取决于辐射场的强度。

方法

在每项实验中，一组昆虫分别在距移动电话天线 30 或 20 厘米处暴露于 GSM 900 或 1800 辐射下，在每种辐射类型下都会出现生物活性“窗口”，另一组昆虫在距金属网格 8 或 5 厘米处暴露于其中，金属网格屏蔽了两种辐射类型的微波辐射和超低频（ELF）电场和磁场，使得两组辐射强度大致相等。然后比较两种辐射类型下各组对生殖能力的影响。
