There has been something called a Pegasus framework on my iphones since the 5s and now in my xr. I have seen other people question the same thing on apple dev site but just as i never got a response from apple about what it actually is, neither have they.
There is also a Pegasus Arm64 too.
Dealing w apple about finding Pegasus on my phone since 2016. They have ignored my request for help until now and technical support saying there is not much they can do about it.
Aluminum foil actually works as an antenna to direct more of the bad stuff to it rather than away from it. A study done on the effectiveness of tin foil hats shows it brings more bad waves toward a person rather than shielding or blocking them.
Huge magnetic storms or even warfare weaponry like dew etc will not be phased by aluminum foil.
Best option is to look at materials used in aerospace/space travel. They deal w a lot of radioactive areas and need to be protected at all times.
