12 year old invents Mexican border tunnel detector

Since the Department of Homeland Security does nothing
to protect us from the hundreds of border incursions by
Mexican Army Troops, they sure can't be expected to
stop the drug and terror tunnels being dug across our
border.

(And the state of California makes it illegal for any citizen
to own a weapon to stop Mexican troops from invading
their property or the state -- anything that uses a .50 BMG round)

A 12 year old kid at Muirlands Middle School in San Diego
discovered that scientists could look inside pyramids with
cosmic rays to look for chambers and tunnels and decided
he could use the same equipment to find terror tunnels
along the border.

He built the machine as a science fair project.

It works fine.

The school is not too happy about this - - (diversity, all cultures
are equal, there are no borders)

This school won't even let the kids say the Pledge of Allegiance.

Abstract
Subsurface cosmic-ray muon intensity depends on the amount of material above the point of reference and is therefore influenced by anomalies in rock density. Because such anomalies might be caused by geological structures (e.g. ore bodies), cosmic-ray intensity measurements have been used for geophysical exploration. Recently, cosmic-ray muon intensity measurements have been also proposed as a method to detect tunnels. The feasibility of this application depends on the type of radiation detection apparatus (it must fit into a bore hole) and on the magnitude of the signal by a tunnel. If the signal is too weak, then the required observation times are estimated for a projected bore-hole radiation detector and for tunnels with a 2 m diameter. The estimates show that a reasonable upper bound for the detector depth is about 30 to 40 m if the observations are to be used in a tomographic reconstruction of the density field. The required observation times at that depth are of the order of days. The upper bound for the depth of detectable tunnels is less than the quoted bound for the detector depth. It might be possible to use the method at greater depths if special data interpretation techniques are developed that take into account prior knowledge about the tunnel, e.g. its anticipated direction.
