> they're infrequent and small

So far. Now you're introducing new technology. Are you comfortable prognosticating that it always will? Are there no lessons to be learned from previous tragedies, in particular, how _small_ radioactive sources are _way_ more dangerous due to peoples inability to identify them and tendency to pick them up?

You introduce medical radiation sources into a country without radiation controls and just a few years later you have an outbreak of tragedies. I'd rather not learn the lesson again the hard way.
