Later down the article is another story:

David: So, my guess is they were making some sort of secret Geiger counter and they wanted to be able to take it around and look for, I don’t know, people making dirty bombs maybe? But not have it looked like a Geiger counter.

David: if you wanted to go and check if there’s any signs of radiation in some place where you’re not officially supposed to be checking, you’re on a tourist visa in Tehran or something, this would be a very useful device. If you’re arrested with a Geiger counter you’re in trouble, but if someone looks at your iPod and the iPod works and it plays music and it’s totally normal, you’d be much safer, right?

Adam:Yeah, totally. So, they built this and then?
