Slotin died from X-ray + neutron radiation. Like Slotin's co-worker and student Daghlian less than year before him. Yes, there was blue flash and wave of heat. It was from air ionisation, not Cherenkov. This is a common misconception about Cherenkov in air.
The other (irradiated) bystanders described the flash as originating from around the sphere Slotin was playng with. If your eye fluid was shining, your vision would be opaque and you would not be able to determine where it came from.
The intense buish glow around nuke shroom is from radiation produced by intense decay of the short-lived fission products. So you are right, it is probably gamma and beta.
Soon you will be able to visit and play in Chernobyl in from your home. The upcoming S.T.A.L.K.E.R game (inspired by bros Strugatsky sci-fi post-disaster novel) was re-enacted in Chernobyl. The screenshots are impressive:

There was far worse accident in US, than 3Mile Island. Tens of tonns of plutonium cought on fire in a nuke factory, with Denver few miles downwind. They put it out with water, almost causing criticality

Friend who lived in Kiev at the time of Chernobyl told me the whole capital was evacuated twice, the second time in the fall when all dried leafs with accumulated radiation went dry and produced enormous amount of radioactive dust.
There was guy in Prague who was using dimethylmercury to make trimethylthalium. His experiment went exotherm and spilled, he cleaned the spill. Next day his vision was blurred, and shortly after he was no longer able to talk and stand upright. He died couple of weeks later in horrible spasms. I used to remember his name.
The observed shining was caused by white-hot burning graphite.
Cherenkov radiation is not observed in air (you need particles with mass traveling with speed higher than the speed of light in given medium , and the optical density of air is low (close to vacuum), the particles would have to travel at speeds near to c - which are difficult to obtain because of relativistic effects. (You can get that from accelerators, but not from fission) You can see Cherenkov typicaly in water - the blue shine around immersed fuel rods or intense radioisotope source.
There is similar-looking bluish shine/flash around extremely strong sources, like criticality accident with Pu, U, or in nuclear explosion (the mushroom has bluish envelope). This shine is caused by intense ionisation of air molecules by radiation, mostly X-ray. The recombination of ions produces excited states whis give away the surpluss of energy by emission in UV/vis , which also appears bluis white.
I am afraid the children in the nursery actualy did try the separation surgery and now they have to resort to excuses like:
"The mystery amphibian is currently the subject of a frog-hunt after it hopped away and disappeared as staff at the nursery showed it to curious parents."
Shuttle moves wing flaps on similar principle - by compressed gas (hydrogen+nitrogen) from hydrazine decomposition. And with using both fuels (peroxide+hydrazine) at the same time, you would need no complicated hydraulics to move your legs - just a nozzle would be enuf.

1. You can patent substance if it is new invented material (which does not occur naturaly, in plants or corrals, for example). The tiniest possible modification of the naturaly occuring substance can be patented, as long as you can prove that it does not occur naturaly and you can tell the differnece. (And fake up some argument why it is better than the original stuff) 2. You can patent process of manufacture of anything. This kind of patents is not easy to enforce because it is very easy to modify the patented procedure with a redundant (or insignificant)change and claim it is essential and non-obvious. And companies are not required to disclose their processes, so it is hard to prove they are using the patented method. 3. You can patent the application of the material - the end use. The question then is how obvious or non-obvious the application realy is and what kind of practical examples of the application patent has - proving feasibility of the idea.
I would expect the future litigation involving patents from the second and third category. They need a lot of money to hire big-ass lawyers for bullying other companies. But sometimes it is easier to pay few% on royalities than risking lawsuit. (Unsettled lawsuits, frivolous or not, can make investors nervous, and licencing in the technology looks like prudent investment)
I used to work for a small biotech company which claimed to have key patents for generation and using combinatorial libraries of small drug-like chemicals for pharma research. Everybody is now using the technology, and our company got nothing out of it except for a harrasment kind of "due dilligence" lawsuit from one of the minority investors, which did cost us few millions on lawyers.
Deuterated acetone is fairly cheap (and less viscous than heavy water, so it is a good medium for cavitation). What would realy convince me would be repeating this experiments with partialy tritiated deuteroacetone. This would be hugely expensive (tritium is one of the most expensive common radionuclides) and unpleasant(because of the radioactivity of T). But D+T reaction has so much lower activation energy than D+D and it produces plenty of neutrons, so the detection should be so much easier, orders of magnitude above what they see right now.
(All common fission nukes and the fission parts of thermonuclear nukes are boosted with about half a gramm of T mixed in with D, to generate enough neutrons for complete fission of plutonium before the explosion spills it apart. Hiroshima non-boosted bomb had only 20% of theoretical yield. The infamous "Neutron bomb" is just a small boosted plutonium fission nuke, overboosted with excess T+D mix and without a reflector shield, so that excess of neutrons is produced and allowed to escape)
What you do not want to get is an ambitious psychologist with 2 years of college and fresh councellor's certificate. (She is gonna cure your PTSD through re-living with you your trauma - no matter what's wrong with you).
What helps is a private talk with a friend or mom, lot of sleep and active program. I can't see how virtual reality videogame-like setting can do any good for PTSD.
Modafinil is given to narcolepsy patients and it works very well. The long distance runners are nowadays frequently busted and disqualified for Modafinil doping. (Modafinil is available on internet and its synthesis is easy enough for somebody to make it in the garage.)
Modafinil has pretty clean profile, allows to stay up without sleep for several days in the row - like a meth or coke binge but without the high-strung mania, poor reasoning, jitterness and clenched jaw. Modafinil does not give any pleasurable high and the resulting sleeplesness is very annoying - especialy after second or third day. Lab animals kept on Modafinil for weeks without sleep became immunocompromised and died from massive internal infection.
"The ideal warfighter is an endurance athlete" - Many endurance athletes would have doped themselves to oblivion if they could get away with it. In the army, it will not be left to the individual choice - and be sure army will get away with it. But they need a new "gear" which doues not have the public exposure problem.
(By the way, Russians did army reserch in 70s' into "non-typical stimulants" and they come up with Modafinil like drugs - producing stimulation without the manic/serotonin-syndrome side effects).
US beef producers use Trenbolone synthetic steroid anabolic to muscle-up calves. It is applied as a thin tube stuck into ear of cattle. (Anabolics work best when injected, frequent injections are not practical - hence the slow-release modified formulation of steroid stuck into ear). Bodybuilders get trenbolone from farmers (they can't buy anabolics legit in US). Since they do not want to walk around with a tube in the ear, they extract trenbolone from the tube formulation and inject themselves daily with the stuff in form of extremely painful subcutaneous injections. They call it "making their own gear"
1. Stainless steel is probably good enuf, especialy at freezing temperatures at Europa 2. It actualy rains sulfuric acid on Venus and the surface temperature is 350C there (and 90 atm pressure). Russians managed in sixties, although their probes did not last much over 1 hour before malfunction.
