RE: [Vo]:Re: The appearance of muons are explained by SPP theory.Hi Bob/All:
Not sure what the questions are, but here are some thoughts/info... Muon ionization occurs as it passes through matter/tissue. The degree of ionization will (amongst many factors) depend on muon energy. Your/my bodies are amazing at compensating for defects caused by radiation... >From the following references, Terrestrial Muons are about 4 GeV.

Mark-- Per your reference I note the following: The reference suggests to me that normal shielding of a mass should stop muons, their reactions being primarily, ionization and Brehmsstralung. I think even 6 GEV protons are stopped by less than ten’s of meters of rocks per the wiki reference---???

From: Jones Beene || From: Bob Cook || Muons appear in Cosmic rays AFAIK. They must be relativistic to exist as long as it take to travel from the Sun to Earth, given their low energy decay rate at non-relativist energies. Cosmic ray muons would be even more relativistic with longer apparent lifetimes. | Muons are actually made in Earth’s atmosphere from Cosmic ray impact with air. They aren’t coming from the Sun. | Wiki sez: About 10,000 muons reach every square meter of the earth's surface a minute; these charged particles form as by-products of cosmic rays colliding with molecules in the upper atmosphere. Traveling at relativistic speeds, muons can penetrate tens of meters into rocks and other matter before attenuating as a result of absorption or deflection by other atoms.[5] I would further like to add that the majority of Cosmic Rays (somewhat a misnomer since the term mainly represents High Energy Particles, approx. 89% of which are protons) are believed to originate outside our Solar System (from supernovae).
