Rays to nab nuclear smugglers

Topics: General Science

US researchers plan to use energetic particles that shower Earth from space to detect smuggled nuclear material held in vehicles and cargo containers.

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.
