Researchers in the United States plan to use space based energetic particles to track smuggled nuclear material. Cosmic ray muon particles strike the
earth at a rate of 10,000 per square meter every minute. By tracking the muons the scientist hope that they can see through lead and other shielding
material that might otherwise mask a radiation source.

These cosmic ray muon particles strike Earth at the rate of 10,000 per square metre every minute.
By tracking the muons, the scientists can see through lead, steel and other heavy shielding that might be used to mask a radioactive source.

The research is being undertaken an Los Alamos Nuclear Laboratories. It is estimated that the average muon can penetrate 1.8 meters of lead which is
more shielding than your average smuggler would be able to easily move. This would be very beneficial to track material and prevent a nuclear or dirty
bomb from exploding in the United States. While it seems that it is a portable type detector, I wonder if it could be spaced based.
