how can I usb tether between two android phones

I want to access the internet connection of my first android phone with my second android phone, via usb. I am sensitive to wifi/network radiation emissions, so I want to connect the first phone via wifi or 3G network to the internet, and have internet access through a long usb cable, from my second phone, set on airplane mode. I have a Galaxy S2 HD LTE SHV-120S Android version 4.0, rooted and stable The second phone I have yet to purchase. Are there apps to enable this? Drivers?
