This radiation occurs only when a phone call is active, right?

As in, having a phone in your pocket all day without receiving any calls is not the same level of radiation as if you had the phone up to your ear while taking a call?

No. If you have a modern smart phone, it will be talking to the cell tower all day long. All those real-time updates from various websites and services, they need to talk with your phone through the cell tower constantly, and the apps need to talk with the network.

If you want the phone to stop transmitting, you have to either put it in airplane mode, or at minimum shut down cellular data. If you shut down cellular data, the phone will be quiet, and only talk with the network when you receive a call or text.

This is what people don't get. Modern smart phones are constant microwave transmitters unless you actively shut it down. You stand in a bus with 20 other people? You have 20 transmitters all around you chatting with the cell tower. It's a microwave soup.

Thank you, that makes a lot of sense.

Do you think those Faraday pouches would help or do nothing?

If it's a good pouch, it will completely shut the phone from the cellular network. No radiation will get out, but nothing will get in either. You might was well put it in airplane mode instead and save your money.

You see how it works? If the phone can't talk with the network, the network can't talk with the phone. Sure, you'll not get radiated, but your phone will be useless too. Airplane mode does the same.

I figured that would be the case, but was wondering if the pouch would be more "protective."

qwop

Well if you want a little nitpicking, in theory a good pouch blocks the minute radiation from the phone's CPU and electronic circuitry too. So yes, in theory it's more protective. Because it will block "more" than just airplane mode (which only shuts down the antenna, but not the CPU).

So a pouch is much closer to turning the phone off completely. That's the closest comparison. They are pretty good, but still not as good as turning it off. However if you're Snowden and afraid of wiretapping, then turning the phone off is not enough - you turn it off AND put it in a pouch.

If you want to kid yourself, go for it.

Thanks for your helpful clarification.
