Smartphones may be leaking more radiation than we think

Apple and Samsung phones released over the last three years may be producing radio frequency radiation at levels higher than current Federal Communications Commission limits allow, according to a report by the Chicago Tribune. Scientists and consumers have shown increasing concern that radio frequency radiation from our devices may have adverse effects on human health, especially with 5G rolling out across the globe. The new report demonstrates that older phone models, operating in the 3G and 4G bands, have the potential to exceed the FCC's safe limits by up to as much as five times.

Smartphone manufacturers are required to abide by the FCC guidelines in regard to radio frequency radiation absorption by the body. The current measure used to determine the safety limit is known as the "specific absorption rate," or SAR, and the FCC set this at 1.6 watts per kilogram (1.6W/kg), averaged over 1 gram of tissue. The FCC states that this limit is "well below that at which laboratory testing indicates ... adverse health effects could occur."

For a phone to receive approval, the FCC states that any device will never exceed the maximum SAR level, but the Tribune's investigation shows a handful of older models do.

The Tribune's extensive investigation tested 11 different models: Four iPhone models (the iPhone 7, 8, 8 Plus and X), three Samsung Galaxys (the S8, S9 and J3), three Motorolas (the e5, e5 Play and g6 Play) and a BLU Vivo 5 Mini. The phones were tested by RF Exposure Lab, an FCC accredited laboratory in San Marcos, California. The investigators placed smartphones within 2, 5, 10 or 15 millimeters of a "simulated body" -- a mix of sugar, water and salt -- and measured levels of exposure with a series of probes.

Problems with cell phone RF levels has always seemed to be with the wattage, ref the older analog phone the pulled because they put out too much juice and people’s heads were warming up.

That’s the deal that gives me pause with the newer LTE and 5G.
Not so much with the phones themselves but with the towers and signal propagation.
They aren’t just simple towers broadcasting a general RF.
Their directed and phased to focus signal to support the heavier data loads.
They even utilize Neighborhood boosters to aid in signal integrity.
I do not know how dangerous this is but it has to make you wonder. One would hope these companies would at least be motivated by self-interest and ensure these new technologies are safe. That’s not always a sure thing though is it.
