Abstract

This review study discusses the public perspectives based on cell phones radiation exposure to particularly the human brain, concentrating on the behavioural effect and disease factors due to RF exposures. Health endpoints reported to be associated with RF which include brain tumours, genotoxic effects, neurological effects, immune system deregulation, allergic responses and some cardiovascular effects are classified and reviewed. This review however showed that there is strong and robust evidence that chronic exposures to electromagnetic frequency or radio frequency or microwave fields across the spectrum, through strength, consistency, biological plausibility and many dose-response relationships, cause increased rates of brain cancer and other carcinogenic symptoms. It can therefore be related that there is no safe threshold because of the genotoxic nature of the mechanism that may however be involved. The discussed study explains that the cell phone induced effects upon the blood –brain barrier permeability and in continuous hours of exposure to RF radiation may result in significant increase in protein extra vasations. Animal species of the sub group reviewed in this study are characterised by symptoms such as a decreased loco motor activity, increased grooming and reduced memory functions due to continuous long hours exposure to RF-EMR at specified absorption rate during their early days of infancy.
