Plain English Summary
Japanese researchers exposed rats to cell phone radiation (1.439 GHz) for 2 years to see if it would promote brain tumors in animals already given a cancer-causing chemical. The EMF exposure did not increase tumor rates or accelerate brain cancer development at either exposure level tested (0.67 or 2.0 W/kg SAR). This suggests that chronic cell phone radiation exposure may not promote brain tumor growth, at least under these specific experimental conditions.
Study Details
The present study was designed to evaluate whether a 2 year exposure to an electromagnetic field (EMF) equivalent to that generated by cellular phones can accelerate tumor development in the central nervous system (CNS) of rats.
Brain tumorigenesis was initiated by an intrauterine exposure to N-ethylnitrosourea (ENU) on gestati...
There were no inter-group differences in body weights, food consumption, and survival rates. No incr...
Thus, under the present experimental conditions, 1.439 GHz EMF exposure to the heads of rats for a 2 year period was not demonstrated to accelerate or affect ENU initiated brain tumorigenesis.
