Without reading the article, should we assume this kind of technology can be used to help college student cheat on tests?

If you will always have access to something, is it cheating to make use of it? The philosophy behind no calculators on exams (or similar tools) is you might not have access to the tool later.

New Neutron Scatter Camera to Detect Smuggled Nukes 125

Posted by ScuttleMonkey on Monday November 26, 2007 @03:15PM from the size-matters dept.

Researchers at Sandia National Laboratories in California are developing a new neutron scatter camera that they claim will be able to detect radiation through much more shielding and at much greater distances than traditional tech. "The neutron scatter camera consists of elements containing proton-rich liquid scintillators in two planes. As neutrons travel through the scintillator, they bounce off protons like billiard balls. This is where "scatter" comes into play -- with interactions in each plane of detector elements, the instrument can determine the direction of the radioactive source from which the neutron came. [...] Computers record data from the neutron scatter camera, and using kinematics, determine the energy of the incoming neutron and its direction. Pulse shape discrimination is employed to distinguish between neutrons and gamma rays."

Heh. It wasn't neccessary. When the dogs saw how loudly my .45 barked, they all left. Didn't actually shoot the dog, but came close.
