Radiation Exposure Level Identification of Cellular Phone in Standby Mode

Cellular phones are playing an important role in technological devices in today’s world. People start to use cellular phones at early ages. Even kids have their own cellular phones as a precaution for their security. However, researches evaluating long term use of cellular phones on safety of humans in respect of radiation emitted from cellular phones have not completed yet. Until these researches are concluded, users of cellular phones should be prudent not to be much exposed to its radiation. In this context, there are some advices from experts to minimize radiation exposure level of cellular phone such as using headset while speaking, sending SMS instead of speaking if it is possible, and turning it off while sleeping at night. In this study, it is aimed to show the effect of staying cellular phone in standby mode on radiation exposure level sleeping in bedroom at night. For this purpose, some measurements were carried out with Narda EMR-300 radiation meter which has a capability of measuring total electromagnetic radiation level from 100 kHz to 3 GHz frequency. Recorded values are compared with national and international limit values determined by International Commission on Non-Ionizing Radiation Protection (ICNIRP).
