Actually, some telephoto lenses were and remain classified. I am not joking, they're used in crap like satellites and U-2 spy planes.
Had one idiot try that question with me, I introduced them to a brand new substance called reinforced concrete and offered them the opportunity for an extremely close and intensive examination of the substance.
Interesting bit of history, Akiko Takakura was 300 meters from the hypocenter of the Hiroshima blast, inside of the bank vault of the bank she worked at. Survived unscathed - well, physically. Mentally, not so much. Went into the vault at work as a ho-hum business as usual day, bright flash, rude noise and shaking building, come out to find insta-cooked people, yeah, that'd mess anyone up.

@neuralmute OK, we'll dig him up and charge him with suicide.
Laws against suicide need to be properly targeted. Now, given what was presented here, beyond ethanol intoxication into duty hours, just which suicide attempt was one to curtail his access?
I do have an answer - his first exposure.
I also noted, he was a loner, which is a potential exposure to risk source. Nowhere a clincher, but one needing to be examined and alas, was ignored instead.
That's a major oversight failure, the company wants to keep a worker on duty to make money, which is the company's purpose and its officers duty. Oversight ensures that insulation gets removed and action taken. Missed, after deleterious personnel actions began, access remained and worse, if access got denied, he'd be abandoned while in need.
Some years ago, we were assigned a medic that had discharged after a tour in South Korea.
SSDD, we were assigned a hell of a lot of reassuring numbers of personnel, diluting some deleterious personnel issues that plagued our organization since the inception of this nation.
Long story abridged, the man exhibited outward charm, interacted well with the team. But, when alone, he would argue with someone not present and even strike his own face during a violent altercation. He also made gestures, during a motor movement that I replaced one of my privates in as driver (not suspicion at all, the private was ill and lacking other licensed drivers beyond one new driver, I've never asked that which I wouldn't do, so I drove. Passing a well placarded elementary school, he made gestures, after calling my attention to him, of shooting at the school.
He passed one psych eval, he failed a second one after other, thankfully innocuous incidents.
After he was discharged under compassionate grounds, he was found sleeping in our armory. The XO of the battalion wanted him arrested for trespass. I managed to divert that and personally drove him to a VA hospital and stayed there, he was refused treatment due to budget, now he's got God and an NCO behind him.
NCO prevailed, News at Six or take care of someone we owe, decide now, well and properly.
A few months later, I ran into him in town. Working, for a change, sane enough to survive in the presence of insanity of the populace, eating well.
He did better than I've done after losing my wife of over 40 years. Took me a week just to be able to eat once a day. Nearly a month before I could tolerate two meals a day.
I've only recently been tempted for three meals a day, the "requirement" also being nonsense.
Last I heard before moving halfway across the country, he's finally fully functional. Given our knowledge and ability, that's the best outcome.
Me vs the loss of my wife, the jury's still deliberating. :/
Add in BS wage lowering, not suicidal, I'd call it homicidal, save for the cidal bit, destroying a dishonorable business that bitches over turnover that's their fault, yeah.
It'll even out, learned that from hard won experience.

It'd essentially start at peak heating, since it's originating at the densest part of the atmosphere. I'll assume tumbling adding inefficiencies to movement, sideface being unlikely due to the fluid dynamic, which I agree, are far from static. There'd also be ionized components to further confound trying to calculate matters and he also treated it as a uniform object that would fully melt, then boil as a unit, rather than melt from outside inward as has been observed for other hypersonic objects passing through the atmosphere. The core of a meteor doesn't instantly boil while the surface is being superheated and bolides tend to fail structurally due to the aerodynamic deceleration forces overcoming their binding energy more than anything purely heating related.
More probably, the cap would be partially melting, losing strength as it's heated and aerodynamic forces driving pieces off as it traveled until sufficient mass was lost that only fragments were traveling and decelerating much as bolides would be traveling in pieces after a fireball explodes.
I suspect a lot of the modeling has already been done that would help in calculating this, but much would be related to railgun work that remains classified. As it was a decidedly non-aerodynamic body to begin with, the stresses would be beyond immense, that the object is a disc and not a blunt body, conic, biconic, etc body just increases compressive strength failure as a mode of fragmentation of the body's chances tremendously.
Then, to further muddy the waters, there's a major assumption that the initial estimation of velocity could be wildly off, as even the shape of the cover once it departed from where it was welded is unknown. Did the weld fail and it's just largely cover? Did it bring any parts of whatever structure it was welded to with it? The heating isn't immersive either, it's heated by the inferno just in front of the shockwave and modeling that is devilishly complex with known shaped objects, such as blunt body, aerodynamic body, cone body, etc.
Most likely, it'd have come apart fairly early on, much as Columbia came apart, for much the same reasons.

@mitchellspanheimer1803 metal shielding is even worse, especially with beta. Remember, Cs-137 is a 0.5 Mev beta source and a 0.6 Mev gamma source. Bremsstrahlung radiation will be emitted by metal when a particle impacts the metal atoms, which can then ionize a path through the chip itself. Some plastics would be far more effective in protecting the circuitry than metal.
In space, one faces mostly protons and beta, along with x-ray and a touch of gamma, all save the EM generating bremsstrahlung radiation from the spacecraft hull. Thankfully, one doesn't have neutrons or protons to really foul the camera in the case of Cs-137, but damage from gamma should be minimal to absent at that energy level. As a hint, thunderstorms can generate gamma in the 100 Mev range, we don't see cameras failing from that. Pair production is quite unlikely at that flux and energy level.
Oh, another tidbit, I-131 is used in nuclear imaging, had such testing done for my thyroid. It puts out around 0.364 Mev, which goes clean through the body to be easily detected. The Cs-137 is harder by a little, but magically was blocked by a hand that should've only barely attenuated some of the beta and not a lick of the gamma.
Were such an offer real and I ran into it and could verify it as a source of some type, I'd buy it and call a friend who's a nuclear health physicist to verify by a proper survey. Then, if it was something like Cs-137, call the NRC and the military installation he works at to see who wanted to take custody of the damned thing. Better to get it off the street and market and into proper custody than pray it doesn't turn up used in some terrorist attack or irradiating a neighborhood.
I'd also get the tag number of the seller and if possible, the VIN from the dashboard. The NRC would certainly want to have a conversation as to where such a hazardous source originated.

Well, we've actually had cold fusion for ages. Not gainful, hell, it's a hell of an energy sink, but then neutron generators aren't energy sources, they're neutron sources.
I remember one model at a national lab that is literally smaller than the end of one's thumb, generates quite a lot of neutrons for a bit, draws tons of power, produces really nasty electric bills. ;)
Farnsworth fusors are excellent cool fusion devices, only raises one's electric bill moderately to massively.
Hollywood, well, they've forgotten the first law of thermodynamics, TANSTAAFL. They're also clueless about neutron embrittlement, but then they also still rely upon high explosive automobiles (all cars explode in Hollywood, at the convenience of the script) and electricity is magic.
Weird Google experiment though, if I'm checking for fusion reactions, I only really need to look for two outputs, thermal and neutrons.
Want cheaper cold fusion? Go lithium. Won't generate gainful power, but lithium is weird, will fuse or fission fairly easily. Fission it, get tritium, fuse it, get a really big electric bill - oh wait, you'll get that either way.
Don't get me started on their infinite supply of ammunition and most of that genre's infinite supply of smokeless powder (if it was actual gunpowder, well, it'd be patently obvious given gunpowder's notoriety for its complimentary smokescreen on firing even a single round)...

...before he was tortured to death by radiation.
One can't be more spot on, every fatal case of radiation exposure was a fugly death, redefining agony in many cases. Bad enough that the DNA was badly damaged in the exposed cells, even the cellular machinery was badly damaged or destroyed.
Sounds like major depressive disorder or severe bipolar, coupled with easy access to a cat 1 source. That's already a potential disaster, add in ethanol, it's fortunate that he at least had a conscience.
Ir-192 is plain out evil, due to its short 78 day half-life. Just maintaining the things had to be challenging, due to the brevity of the source's utility!
But, why those sources went home on company vehicles is beyond me and now, the fodder of my nightmares. Way too easily stolen that way!
"So, what do you have for show-and-tell, Johnny?"

It was an unmitigated disaster!
To the reputation of an absurd number of people, agencies and companies. It wasn't so good for the reactor either. I reviewed imagery of the core after the accident, that wonder of modern engineering wasn't that any longer, it was a Greek tragedy. The only thing uglier was Fukushima's cores.
Couldn't find any imagery of what's left of Chernobyl's core, which is just as well, I'd probably become ill seeing what happened to that engineering.
Beyond those disasters, well, I live 3 miles from the island, everyone's still here and annoyingly, we still need street lights at night - nobody and nothing is glowing.
TMI, a lesson on precisely how not to keep the public and press informed during a mishap or major accident. The truth shall set you free, even if you're stuck admitting that you're in the middle of recovering from a major goat screw event.
Oh, from the report, the flashing indicator was on the obverse side of the main console and was noticed by the shift relief operator as he arrived.
Always remember the Shepard's Prayer, Alan Shepard praying when he entered the space capsule prayed, "Oh Lord, please don't let me fuck up!".

@tom.m you neither zero or adjust fixed iron sights, which by definition are... Fixed.
And those rounds arc at one rate on earth and a substantially different rate on the moon.
Again, sights are designed to account for a fair bit of parabolic trajectory "out of the box", for adjustable sights, simply by virtue of being designed to be used on earth. A GI model M1911A1 has fixed sights. It's designed to fire a bullet mass of 230 grains and the sights are fixed at 25 meters/yards. If fired at 25 meters on the moon, the round will always impact high by around an inch (drop of 2.6" at 25 meters for 230 grain in air, more likely 1 1/4" high, accounting for drag vs vacuum). And 45 ACP out of an M1911 series is ideal for such calculations, given its range, extremely prolific documentation, known drag and mass for a NATO round, etc.

@tom.m boy, you love to display your ignorance for all to wonder at!
First, I mentioned fixed sights for a reason. You never could zero fixed sights, you never will be able to zero fixed sights, you never will in the future be able to zero fixed sights - they're fixed. That's to provide a simple example to a simple mind.
Now, your magical reticle sights, great job, the marks are for earth, so let's say for easy of math, the bullet drops six inches per tick at 100 meters. On the moon, it'd drop less than one inch, now you're way off, as earth gravity is six times higher and then there's drag on the bullet, as expressed in the math via the ballistic coefficient.
A tall mount further introduces parallax errors, dropping accuracy.
But, what would I know? I'm only a competition shooter and experienced in rocketry.

@TallinuTV well, space suits do have a type of armor, it's the micrometeor protective layer. Consider that micrometeors are cooking along around Mach 12 - 15 or so, that's a wee bit faster and more energetic than a mere bullet. So, goosing that up a bit shouldn't be a big deal, as one then accounts for a much slower, but heavier projectile. Basically, the overgarment is a cloth version of the Whipple Shield, which is used in all spacecraft, including the ISS.
Without that protection, a mere grain of sand sized meteor, which are common, would drill through a bare space suit and vaporize inside of an astronaut.
There was one spacesuit breach during the shuttle program. A tension bar inside of an astronaut's glove broke loose, cutting the astronaut's hand and through his glove, exposing his hand to space. His blood sealed the hole and the hole went unnoticed, that whole adrenaline thing and EVA thing going on. It was noticed when he removed his gloves inside of the shuttle.

@Vaprous sights are rather useless for lunar distances anyway. On earth, someone standing just showing over the horizon would be around 5 miles away. On the moon, less than 2 miles. Given sights and stability of a firing platform, such as a sniper rifle system, suffice it to say that shots at a mile and over are beyond difficult.
Add in the terrain, well, it's hedgerow country done with rocks and small craters and large.
Now, line of sight weapons that could cause seals to fail would be far more effective at ranges great and small, despite the inverse square law. But, I'll stick with my standby, a few cases of vodka.
Because, fighting on the moon is about the stupidest idea ever considered since the military asked Carl Sagan to figure out how to make a nuke blast on the moon look impressive. Short answer, it's impossible and would likely go unnoticed, as there's no air to hold a fireball.

YuoTvbe not quite true. it's a tenuous atmosphere, but a hard vacuum level one nonetheless.
As in, there is an atmosphere, that is barely detectable., but is present.
And for, well, bullets, not worthy of mention.
But, it is something that exists. Barely. Right up there with farting n a space elevator at a few miles up.
Seriously, there is a lunar atmosphere, it's pretty much a hard vacuum, but tenuously present. Google it, you'll be shocked and amazed.
If there's gravity, there's an atmosphere (ish), just don't try to breathe it, it's still a hard vacuum by our standards. But, even Pluto has an atmosphere.

Given that the capsule of the cobalt-60 source is intact, Homer would never be radioactive, as cobalt-60 isn't a neutron emitter.
But, there's another extremely common source that resembles that capsule, a phosphor coated tritium vial, the tritium also coming from nuclear power plants. Again, he'd not be radioactive, as it's intact. Although, the amount of tritium, were the source compromised would be decidedly unhealthy, it's unlikely to reach LD50 for tritium on a chemical basis. Biochemically speaking, tritium sucks in organic reactions...
As for Cerenkov radiation, it's not only present in water, it can and has occurred in air, the eyes (OK, yeah, that's mostly water) and I've personally observed, much to my horror, its presence in glass.
Really long story there.
Oddly, there have been survivors of prompt criticality accident who observed the glow in the room air. Got sicker than all hell, but they survived. Suffice it to say, any children resulting from them are not on my family's intimate relationship list, as some of their DNA "eggs" got scrambled for certain.
I've been, off and on, reading an interesting IAEA report on criticality accidents. My thought, the entire time reading it and after, "A bunch of 5 year old kids with daddy's loaded gun in their hands". I'm firmly convinced that Homer Simpson is a real person and he bounces back and forth mostly between the US and Russia. ;)
Still, I'm in the market for a cobalt-60 source, so I'll soon be calling around South America to evaluate a few potential sources... :/
No, I'm sure Kyle recalls the orphaned sources at the heart of a couple of accidents and one in Mexico, which contaminated a hell of a lot of US steel that's still in use, you can't wink and smile about those deaths.

nunyabaznus7851 so, lung cancer from asbestos and the other nasty chemicals burned in the tower fires and collapses is precisely the same as lymphatic cancer? That's like saying my testicles and toes are identical structures and trust me, maybe yours are, but in humans that's entirely untrue. Lymphatic cancer is well established in fallout exposure cases as a primary cause. True, not the only cause, but genetic testing can help rule in radiation exposure, as can that whole radioactive lymph nodes thing. And frankly, I'll say something I've rarely ever said, in this, I'll trust the VA.
But still, IRL, feel free to hand me my trusty rusty and tell me more about conspiracy theories and how we're all liars. The hogs are hungry.

@bschleevs2723 meh, I could trivially build a nuclear warhead right inside of my apartment. If it doesn't contain explosives or fissile elements, nobody will care. Literally.
That'll not happen though, as for one, it'd still be quite massive and I'd not want to have to shift the damned thing around when cleaning my apartment and well, I have a small apartment and only keep useful things around.
Like that Americium-241 source sitting over here, just harvested from a recently defunct smoke detector. I'll be throwing together a cloud chamber in the coming weeks, just to have something to do.
A little for the cloud chamber, a little for me... ;)
Yeah, I actually took the source from a dead smoke detector for that purpose. Boy, have they shrunk the source by a lot over the last 20 years! The source on this one is a quarter the size of an old model, pretty much the rest of the circuitry was literally the same, down to the chip driving the unit.

No, there is no criticality possible, as there are two critical factors in achieving a critical mass, a moderator and the proper geometry of fissile fuel. The corium is diluted fuel, cladding, structural components and concrete. The only way it's reactive is chemically, due to the alkalinity of the fluid around it.
Spikes do get recorded, it's called radioactive decay of daughter elements.
The "elephants foot" has decayed sufficiently as to literally be safe enough to sit on and have lunch, although eating in that environment would have occupational safety personnel raising merry hell and rightfully so. Safe to sit on isn't safe to risk exposure to.
As for the original accident, well, that was The Three Stooges meet Home Simpson on the stupidity scale.
Written from visual range of 2 1/4 mile island, it used to be 3 mile, but part melted when I was a senior in high school. ;)
It's shut down, as fossil fuels are cheaper to produce electricity than running a nuclear plant is to run. And well, CO2 will bring the wonders of Venus to earth, making earth the garden spot that Venus is today - to use your level of hyperbole...
