x-ray screening

New air cargo security rules require 100% screening of every shipment. The Transportation Security Administration says cargo from large warehouses with heavy security measures don’t pose a risk and can skip screening, but some say that’s unfair to companies that comply.

1992: U.S. Customs is contracting with a Massachusetts-based company to design and construct an X-ray unit that can examine the cargo inside a standard container in about three minutes.

After years of development work, TSA’s approval for third-party canine screening should provide faster and more accurate air cargo acceptance and security screening, and reduce truck detention at airports.
