Make that 10,000/m^2/sec according to Wiki…
Correction – the standard muon flux 10,000/m^2 at sea level – so the flux is
based on a square meter and the box looks to be far less area – so it could be
perhaps 10-20% efficient.

Ø Dirt Cheap Muon Detector Puts Particle Physics Within DIY Reach
This device is seeing one muon per second at sea level in Boston. The actual
flux is about 150 per second, so the detector is less than 1% efficient. It
would be most interesting for Hagelstein/Swartz to borrow one of them - so as
to place a detector near an experiment which is known to produce excess heat.
This begs to be done.
And the normal muon flux makes the Holmlid claims of laser irradiation, which
are apparently producing 100,000 times greater muon flux, all the more
impressive – if true. Even if Holmlid’s detector is 100% efficient, the results
are extremely impressive.
This could explain why a LENR device, if muons are being produced, can have no
apparent thermal gain at times … assuming muons are a type of energy release
which happen irregularly, along with other kinds of energy release. The muons
have a long life (relatively speaking) and would decay tens of meters away from
the experiment, and be missed normally.
