LHC: druhy beam presiel

[balu@home]

neviem co presne prilieta z vesmiru, ale skor mam pocit ze su to hmotne 
castice, ako produkty roznych jadrovych reakcii. Sposobuju ionizujuce 
ziarenie. Energeticky vyznamne fotony (neionizujuce ziarenie) myslim ku 
nam prilietaju hlavne z nasej najblizsej hviezdy, ostatne su 
zanedbatelne :-)

Potvrdzuje to zhruba aj wikipedia, ale nie som odbornik v tejto oblasti 
takze sa hadat nebudem...
Cosmic rays are energetic particles originating from space that impinge 
on Earth's atmosphere. Almost 90% of all the incoming cosmic ray 
particles are protons, about 9% are helium nuclei (alpha particles) and 
about 1% are electrons (beta minus particles). The term "ray" is a 
misnomer, as cosmic particles arrive individually, not in the form of a 
ray or beam of particles.
