Misconceptions on Cosmic Rays

If anyone has received a text saying about a certain warning that tells people to turn of their cellphones tonight for some time because of cosmic rays, that is a hoax. I was scared a bit, so I researched... Here are the reasons why it is wrong:

1. Our atmosphere protects us from cosmic rays.

2. No heavenly body is close enough to emit or reflect an intense cosmic ray that our atmosphere cannot protect us from. Planets do not emit cosmic rays, and even if they are able to reflect, the intensity is reduced.

3. There is no solar event that is currently occurring. The most recent solar event was around three days ago.

4. Cosmic rays generally originate outside the solar system.

5. Radiation from cellphones and similar devices are infinitesimal and not life-threatening.
