NNSA's [National Nuclear Security Administration, DOE] Megaports Initiative, which began in 2003, teams up with other countries to enhance their ability to screen cargo at major international seaports. The Initiative provides radiation detection equipment and trains their personnel to specifically check for nuclear or other radioactive materials. In return, NNSA requires that data be shared on detections and seizures of nuclear or radiological material that resulted from the use of the equipment provided. The Megaports Initiative has three main objectives: (1) Deterring terrorists from using the world's seaports to ship illicit materials; (2) Detecting nuclear or radioactive materials if it shipped via sea cargo; and (3) Interdicting harmful material before it is used against the U.S. or one of our allies. In cooperation with foreign governments, Megaports representatives determine the most effective placement of radiation equipment for each seaport. Installed sensors then screen cargo containers for special nuclear or other radioactive materials. If anything is detected, the sensors alert foreign port officials of the need to further examine the cargo so they can take appropriate action. (NNSA/DOE, Megaports Initiative, 2008)
