"We scan 100% of the containers coming into the US for radiation all ready.
I am very dubious of that stat. Do you have source or proof for it?"

Well, I can add, that I personally heard Chertoff on FoxNews specifically correcting the misconception, that we only scan a small fraction, he specifically said we scan 100% or words to that effect.
OK. Found you specific source:

A Layered Defense:
Screening and Inspection: CBP screens 100% of all cargo before it arrives in the U.S.- using intelligence and cutting edge technologies. CBP inspects all high-risk cargo.
CSI (Container Security Initiative): Enables CBP, in working with host government Customs Services, to examine high-risk maritime containerized cargo at foreign seaports, before they are loaded on board vessels destined for the United States. In addition to the current 42 foreign ports participating in CSI, many more ports are in the planning stages. By the end of 2006, the number is expected to grow to 50 ports, covering 90% of transpacific maritime containerized cargo shipped to the U.S.
24-Hour Rule: Under this requirement, manifest information must be provided 24 hours prior to the sea container being loaded onto the vessel in the foreign port. CBP may deny the loading of high-risk cargo while the vessel is still overseas.
C-TPAT (Customs Trade Partnership Against Terrorism): CBP created a public-private and international partnership with nearly 5,800 businesses (over 10,000 have applied) including most of the largest U.S. importers -- the Customs-Trade Partnership Against Terrorism (C-TPAT). C-TPAT, CBP and partner companies are working together to improve baseline security standards for supply chain and container security. (We review the security practices of not only the company shipping the goods, but also the companies that provided them with any services.)
Use of Cutting-Edge Technology: CBP is currently utilizing large-scale X-ray and gamma ray machines and radiation detection devices to screen cargo. Presently, CBP operates over 680 radiation portal monitors at our nation’s ports (including 181 radiation portal monitors at seaports), utilizes over 170 large scale non-intrusive inspection devices to examine cargo, and has issued 12,400 hand-held radiation detection devices. The President’s FY 2007 budget requests $157 million to secure next-generation detection equipment at our ports of entry. Also, over 600 canine detection teams, who are capable of identifying narcotics, bulk currency, human beings, explosives, agricultural pests, and chemical weapons are deployed at our ports of entry.
