It won’t spread very far due to its density though. I wouldn’t like to be in the enrichment room itself if the bombing did rupture some active centrafuges but outside should be fine.

Uranium 235 isn’t very radioactive in the absence of a neutron flux. It’s fissile which means it will undergo a reaction when it absorbs a neutron and its fission products are radioactive but the biggest risk from handling uranium (below a critical mass) is its chemical toxicity rather than radioactivity (and that applies just as much to the non-fissile U238)

It’s just a BS survey by an ISP, I wouldn’t read too much into it. Aside from anything else it would imply that 29% of adults in Ireland don’t sleep for more than an hour at a time…
