Just out of interest what arches in arrivals?
At all airports I've arrived at anything like recently in the UK (LTN, LHR, LGW, LCY mainly) there are some grey metal arches you walk through after baggage reclaim and customs but before arriving in the arrivals hall. There is no information on them and they don't inhibit you walking through in any way, and it would be easy not to notice them. There is very little information available about them, but I did a bit of research and found that they are to catch people attempting to bring in radioactive materials in order to help counter the threat from dirty bombs and similar.
Unsurprisingly I can't find any photos of them, but next time you arrive at a UK airport look out for them, they will be there.
They are mentioned in this article:
