I would have to say no.

XRF units usually use something like fe52 and ca something or other as their exciters, and both in the micro curie range.... even upwards of 1 mev I'd have a hard time believeing that there would be a hazard.

I typically use an arc / spark spectrometer so I'm not 100% on the xrf's but I know, have seen, and used xrf's on piping that held some pretty nasty stuff.
