For those of you now eyeing your cell phones suspiciously, it is worth noting that both the National Cancer Institute (NCl) and the World Health Organization (WHO) say there is no evidence to support the assertion that cellphone are a public health threat. But a number of scientists are worried that there has been a dangerous rush to declare cell phones safe, using studies they feel are inadequate and too often weighted toward the wireless industry's interests. An analysis published by University of Washington neurologist Henry Lai determined that far more independent studies than industry-funded studies have found at least some type of biological effects from cell-phone exposure. A strong link between mobiles and cancer could have major public-health implication. As cell phones make and take calls, they emit low-level radiofrequency (RF) radiation. Stronger than FM radio signals, these RF waves are still a billionth the intensity of known carcinogenic radiation like $ \mathrm{X} $ -rays.

But now, new work published this week in the Journal of the American Medical Association says there is an identifiable effect of cell phone use in the brain, but it is really too early to tell what, if anything, that effect means health-wise. There has been a lot of controversy of whether cell phones could increase the temperature of the brain, which in turn could affect energy requirements. Based on our study, we really cannot infer whether this is a bad or could even have potentially good applications so that our finding does not illuminate or enlighten that very important question of whether cell phone exposure could have detrimental effects.
