Is the 6ghz bad for your health?

In my other post I was asking about this new 6ghz band that somehow made its way into my wireless gateway. I lease TG4482A gateway from Comcast, its a dual band meaning it has 2.5 and 5ghz frequencies but now I discovered that a 6ghz frequency somehow got added to my gateway. I have no idea what it does, none of my devices are connected to it, but my main concern is if this frequency  bad for health? 

Thanks
