This incident inspired my PhD dissertation on radiation source search. The techniques to search for sources like this are remarkably primitive, even today. My company works on this tech, but it's hard to get traction because the US government basically stopped investing in CBRN technology around when the Cold War ended, and hardly any other countries take it seriously as a threat.

Not that search techniques would have helped stop this incident, they basically didn't even know it was lost until the capsule was already broken and people were dying.

Can you share your dissertation with us?

University server seems to be acting up a little bit, I think they just migrated to a new platform but this is the link: https://repository.lib.ncsu.edu/items/451b001d-e63a-4968-866...

Wow you got you some markov chains, Monte Carlo, Gamma Radiation, what a fun dissertation. I especially liked the bit about how the NaI detector is not a sphere and sensitivity depends on incident angle. I would never have thought of that. You even did a trip to ORNL, how cool is that!

Walking around with a Giger counter while wearing a hazmat suit seems like fun too, but I suppose it would freak people out. This seems like a much more stealthily way to locate a lost source.

In 1987, in Brazil, a simple metal capsule left behind in an abandoned hospital triggered one of the worst civilian nuclear accidents in history.
