A good place to start is that counting labs rarely (read: I have never seen one) end up on the top floor with beautiful views of your surroundings. No, you get the dungeon labs where sunlight & windows are a rumor, but the radon down there is quite real.
How much radon you have in your subterranean science lair is very much a function of where you are and what your local geology is like. But even in the newest, most freshly heaved from the ocean sedimentary formations you're going to have soon.
GOOD NEWS! You building HVAC takes care of this. Well, it should take care of it. If the HVAC is balanced to actually move air in your room. Have you made friends with the Facilities folks yet? You should really do that.
When you're regarded as a teacher/professor's favorite student over their entire career, it makes it very likely the school administration or alumni association will drop you a line for help, no matter what you went on to do in life.
If you have memories, happy or otherwise, of your teachers having a seemingly endless supply of weird and concerning apparatus for demonstrations, I want to assure you there were SO MANY MORE they didn't use in the backroom and back at their homes.
The things your teacher'd bring out for demos are a function of a few things:
• Where/how old is your school district?
• How comfortable are they are using it?
• How likely is it to break/easy to fix again?
• Have they been speciically forbidden to use it by adminstration?
Medical Emergency vs. Rad is the natural follow up to Fire vs. Rad because the responder priorities are exactly the same: Life, Property, and Environment. Though in some jurisdictions they swap the order of those last two.
Life saving efforts are always top priority though.
Which is why it is such a dick move at the level of war crime to drop/set off a second bomb 10-20min after the first to make sure you nail all the responders doing life saving efforts.
But I digress.
In general, during contamination incidents that also have injuries we do our best to simultaneously decon and render medical attention as close to the site of the incident as safely possible, with priority on treating the injury.
The traditional answer to avoiding NIMBY crap, whatever your particular issue may be, is by building your facility three miles down the road from the ass end of nowhere. Unfortunately, the suburbs will follow you and suddenly it's your fault that you're in their backyard again.
GOOD NEWS: when McMansions attack they bring some support networks with them.
BAD NEWS: not *enough* support network because one of the reasons to move to the sticks is to avoid taxes, so...bummer.
But there was a good thing to really help under resourced jurisdiction that grew out of the catastrophe of the 1991 Oakland Hills Fire: the birth of the Mutual Aid System.
READ: when you call for help, people will come, and everyone will use the same jargon & radios (except NYC)
This scenario is much like when the Local Color brings you a dead radioactive seagull, except this time your surprisingly competent coworkers may have captured an actual live, radioactive, and displeased animal to bring to you.
When you're working in a sampling lab, you get used to receiving some odd things but for all of them it means reducing that odd thing to a useful form for your analytical techniques.
If presented a shitting, pissing, terrified, & angry feral cat YOU DON'T REDUCE THE CAT ITSELF.
Luckily, the cat is presenting you with plentiful samples for in vitro bioassay. Just see if you can collect it without contaminating it with you own blood. That's just bad technique.
If you wanted to do in vivo counting, that's another matter.
Only a few of you failed out of counter-terrorism theater club: when you are handed select choices to investigate, the money wants you to investigate those. The money does not appreciate when you question their premises/choices or study things they didn't pay you to consider.
Your employer clearly has reasons that they've judged these radionuclides to be of concern for use as a murder weapon and they would like to give you money about it. The first thing here is to stop and consider their question: they're asking about murder, not terrorist attack.
This isn't quibbling over semantics, it's a question of intent. Yes, an act of terrorism may kill someone but that person's death, generally speaking, is the goal. The goal of terrorism is *to inspire fear*. You don't have to kill anyone to do that.
