Comparative measurements of external radiation exposure using mobile phones, dental ceramic, household salt and conventional personal dosemeters

Introduction: The tremendous growth in telecommunication world has increased the number of mobile phone users to many folds. The benefits of cell phones are just half the picture. The other half may be a darker one. The main aim of this study is to observe the effect of electromagnetic radiation being emitted by mobile phones on adrenal gland microanatomy and the hormones released by the gland on male albino rats. Materials and methods: Forty-two male albino rats of Spargue-Dawley species were divided into two equal groups. The experimental group rats were exposed to mobile phone radiation operating at 900 MHz while the control group rats were not. At the end of every two months, seven rats were sacrificed to analyse histological and hormonal changes. Results: No changes were seen at the cellular level of the adrenal glands even after six months of radiation exposure. Hormonal assay showed a variation in the cortisol levels of the rats but the changes were within normal range. Conclusions: Lack of appreciable changes in the cellular morphology and hormonal levels even after six months of radiation exposure signify that the adrenal glands are not affected by exposure to mobile phones.

Background/Aim. During recent years, the widespread use of mobile phones has resulted in increased human exposure to electromagnetic field radiation and to health risks. Increased usage of mobile phones at the close proximity raises questions and doubts in safety of mobile phone users. The aim of the study was to assess an electromagnetic field radiation exposure for mobile phone users by measuring electromagnetic field strength in different settings at the distance of 1 to 30 cm from the mobile user. Methods. In this paper, the measurements of electric field strength exposure were conducted on different brand of mobile phones by the call-related factors: urban/rural area, indoor/outdoor setting and moving/stationary mode during calls. The different types of mobile phone were placed facing the field probe at 1 cm, 10 cm, 20 cm and 30 cm distance. Results. The highest electric field strength was recorded for calls made in rural area (indoors) while the lowest electric field strength was recorded for calls made in urban area (outdoors). Calls made from a phone in a moving car gave a similar result like for indoor calls; however, calls made from a phone in a moving car exposed electric field strength two times more than that of calls in a standing (motionless) position. Conclusion. Electromagnetic field radiation depends on mobile phone power class and factors, like urban or rural area, outdoor or indoor, moving or motionless position, and the distance of the mobile phone from the phone user. It is recommended to keep a mobile phone in the safe distance of 10, 20 or 30 cm from the body (especially head) during the calls.
