Rays in the universe: cosmic radiation
We live in a pool of radioactivity since the world began. An average of 240 particles per m² fall on France every second. This exposure caused by cosmic radiation accounts for 10% of the naturally originating exposure to which we are all subjected.
Fortunately, the Earth has a magnetosphere and an atmosphere. Without these two protective envelopes, radioactivity would be so strong that it would make life impossible...
