Does it assist Customs to detect prohibited goods? Are there any problems?

During Module 2 we have discussed some of the technology that Customs uses to examine goods. Research your own customs administration’s use of this technology, whether it is full or mobile x rays, detector dogs or particle analyzers or some other form of technology.
Select one of the examination technologies that your customs uses and in no more than 200 words tell me all about it.
In explaining the use of the technology make sure you tell me what you think about it. Do you think it works well? Does it assist Customs to detect prohibited goods? Are there any problems?
