A comparison of the effects of 900 MHz electromagnetic fields and gamma ionizing radiation in human peripheral blood lymphocytes

Abstract

The usage of mobile phones increased significantly in the last 15 years. The concerns about the potential negative health effects arise, because of the daily use of electromagnetic field (EMF) sources. EMF, produced by cell phones may affect biological systems by increasing the production of free radicals, and even DNA damage. Other environmental factor, with an impact on humans’ life is the ionizing radiation. The main purpose of this work is to compare the effects of 900-MHz radiofrequency fields and gamma-ionizing radiation (γ-IR) on the levels of free radicals and DNA damage in human peripheral blood mononuclear cells (PBMC). The EMF generated, at a power of 2W used for cell phone applications, led to a significant increase in the levels of intracellular reactive oxygen species (ROS), but not in persisting DNA damage 2h post-exposure. In contrast, irradiation with 4Gy of gamma rays increased dramatically both - the intracellular ROS and the DNA damage compared to background. (author)
