NSBP member Calvin Howell leads project applying nuclear physics to safe ports
from Maritime Executive
Two teams of physicists at the
Triangle Universities Nuclear Laboratory
in North Carolina have identified new "fingerprints" of nuclear materials, such as uranium and plutonium that can be used in new cargo scanners to accurately and efficiently identify suspicious materials. Using the world's most intense and tunable source of polarized gamma rays, one team is exploiting characteristic ejections of neutrons from targets upon irradiation, while another team is exploring the energy pattern and distribution of the gamma rays that fluoresce after the photon-matter interaction.
