(CBP unveils $46 million initiative)... Customs and Border Protection unveiled the initiative Wednesday.

They say the $46 million initiative will enhance the security and efficiency of rail cargo inspections at locations throughout the United States. Under the initiative, CBP will replace aging rail scanning systems at 12 rail ports of entry on the US southern and northern land borders with high energy rail scanners. The new scanners use linear accelerators to generate x-rays from electricity rather than radioactive isotopes, producing high-quality images that support faster and more secure cargo inspections. Calexico was chosen as one of the 12 ports where the CBP will install the new scanning equipment. The installation and testing of the new scanners are expected to begin in the fall of this year and will increase the efficiency of commercial rail inspections.
