Hi Mr Slav, since I work in the nuclear medicine industry I figured I would give some insight into how much radiation that source was actually giving off. So we have survey meters that measure in Sieverts per hour (Sv/hr), basically how much radiation as a rate; hence the per hour. An important thing to understand is the Sieverts is a big unit, 1 Sievert is massive amounts of radiation and if we were to have a spill of anything close to that we would have to evacuate the building. So 0.002 Sv/hr doesn't seem so bad right? Nope. That is 2 milli Sv/hr and even that is considered a massive, major spill requiring a radiation safety team to handle the spill. To give even more context our lab where all the radioactive material is stored has a background of ~0.5 micro Sv/hr which is normal, world background. That is 0.0000005 Sv/hr. So 0.002 Sv is 4000x higher than background. On top of all that Cs-137 has a half-life of 30 years so it wasn't going to decay anytime soon.
Considering the atomic age of the 50's america where they put radioactive materials in everything more so than glow in the dark watches for GIs it wouldn't surprise me Since radioactive materials give off TONS of energy rays radioactivity it can really explain all the paranormal stuff
maybe supernatural entities might possess radioactive parallelism? because they are deadly forms of energies themselves the more meditation is being practiced & mastered by an individual that individual emits energies like ultrasound because of which snakes , scorpions etc are attracted due to such high vibrational frequencies since they’re the one’s who can pick up such frequency signals & mainly everything in this world is made up of energy which is again vibration & frequencies perhaps demons or other entities including humans carry such massive energies a person who had summoned a demon said it was like being stabbed the force of the energy was devastating in this world science & occult both coexist even the mind also emits energies which people think maybe the subconscious mind might’ve also have the affinity for being radioactive since its very powerful finally as nikola tesla had said it himself if you want to understand the creation of the world then think of it in terms vibrations & frequencies even he had hinted towards the occult
They couldn't concentrate anything back then to make it radioactive enough to hurt anyone and there's nothing natural that's that radioactive. Even if you were on a cave with uranium ore it wouldn't kill you because there's just never that much in one place.
Definitely possible but most likely was stuff made out of poisonous materials, as radiactive stuff is really rarer compared to poisonous materials. Anyways def possible
Or there was something else going on that no one understood yet. The story of the ‘sessho-seki’ says that anyone who touched the stone (which was haunted by a vengeful Kitsune spirit, ‘Tamamo-no-Mae’) or got too near would collapse and eventually die. Birds flying over it were said to drop out of the sky, even. This stone is located in a volcanically active place known for sulphuric hot springs. It’s likely that this legend arose not from vengeful spirits but from the toxic gasses hiding beneath the earth, which would leak out and poison anyone who got too close.
Radiation and man-made extreme radiation sources are most scary thing. People cannot found or know these exist or not in their walls. Or somewhere else. That time every household didn't have radiation meter. It was big thing for sure. And that's smaller as bunny's poop. Those who missed it were so idiot's that theres is nothing to compare. It's so much radiating, that it would be easy as hell to found, if they want. Even in bigger bucket of dirt. They maybe controlled how much there's water in cement making process, by using this source. It's like light that could see tru material's, backside need's just right type of camera or other sensitive reusable sensor or cluster of those. Who legally makes these, control's where these used and be aware that old one's come back and put away with other hazard materials. That cesium isotope is more dangerous than plutonium metal. Half-life is under 40 year's, so it really dosen't want to exist. That's maybe one big reason why it looses so much particles, bombing those anywhere around.
He can, although explanations are much better than from some other youtubers who are trying to make money on stories they make up. I like his videos, interesting stuff and explanations.
When I worked for a road construction company, my job was nuclear density testing. The machine I used was made by Troxler and used a Cobalt 60 source very similar to this pellet. It did essentially the same thing. Measures density of a substance. You calibrate the machine against a calibration source every day to have a baseline figure for the amount of backscatter radiation so as the source gets weaker with age, the machine is still accurate. The job I did was to test the compaction level of frehly laid asphalt roadbed and surface coat. The more densely packed the asphalt, the less backscatter reading you get to the detector in the machine. I would hazard a guess and say that quarries that use similar equipment are trying to get basically the same thing. There was a similar incident in Australian quarry of an orphan source from a machine that served the same purpose. But apparently it was being taken to be replaced due to age and decay and fell off the back of a truck. On a LOOOOONG stretch of highway with extremely little of anything along the road. The orphan source was recovered safely and an investigation launched into how exactly it happened. And of course, the goal of the investigation was to figure out how to prevent similar occurrences in the future. Hopefully, that helps a bit, and doesn't confuse anyone more. Great video as usual.
This was awesome. I had no idea about Soviet construction, particularly that they're basically named after the Leaders of the era they're built in. Thanks, Slav. This was gnarly.
Those were not the official names, just the colloquial ones. But yeah, they got pretty popular and are still used to refer to the buildings of those eras.
cesium 137 was also responsible for the goiana radioactive incident in brazil, 1987, this radioactive element, in addition to being used in industries, is or was used for radiotherapy too. Also, the cesium 137 is quite safe I guess, because it shoots alpha radioactive rays. However, if this element is not controlled properly, it can turn into barium-137, which shoots dangerous gamma rays instead. I am not a smart guy but I hope this helps as an additional information
Nope. Cesium-137 is a strong gamma emitter and is extremely dangerous. Cesium-137 emits gamma rays with an energy of 0.662 MeV and does not undergo alpha decay.
@@vinudaliyanage3069 it actually emits beta particles and cesium-137 decays itself in it, resulting in a decayment product which is the barium 137 that shoots gamma rays in small amounts. The lifespan of a barium 137 isotope is short but it's enough to destroy a whole body.
@@noob_guardianhd3345 That's actually misleading, as the resulting decay products can be in an elevated state of energy. Now guess what these decay products do? Shoot of Gamma Photons to get rid of this state of higher energy xD
its unbelievable how orphan sources even happen. such an incredibly dangerous material and people handle it like its your child's kindergarten drawing (suspiciously lost).
I come into contact with similar emitters, they are used, for example, in glass factories - to measure the level of molten glass. I worked in a factory where glass bottles were made as a technician - and sometimes I calibrated scintillation radiation detectors that these emitters shone on.
Hey Mr. Slav, I think it'd be a cool idea if you covered the Halifax Explosion. Still holds the title of largest accidental manmade explosion. Crazy event, 1700-ish dead, over 9000 injured. Much love from Canada!
@@Robbel. It was such an insane thing to learn about. Being from Nova Scotia, they taught about it in schools during history classes. I think PBS or something did a short documentary about it but I forget what it's called
Radiation follows the inverse squared law so for every metre distance from the source the radiation reduces to the square of distance. 1M=1/2, 2M=1/4, 3M=1/9, 4M=1/16 which is why they died of leukaemia and not Acute Radiation poisoning. Radiation is used extensively in the measuring industry due to its penetrating power and found everywhere handheld devices like fire detectors to measuring pipes in plumbing. Radiation even used in hospitals to irradiate blood to kill the white cells and prevent graft vs host disease.
Something similar happened in South America. I can't remember the exact details but, radioactive metals contaminated a steelworks because they purchased scrap metal to smelt. Somehow, a radiotherapy device that had a load of cobalt60 pellets in, was disassembled and the metallic pellets were sold as scrap metal to foundries. By chance, a truck carrying rebar from one of the foundries passed through Los Alamos lab after taking a wrong turn and set detectors off. So it was traced back. Thousands of people were exposed.
Never heard of this story but incredibly that f.... orf is in your wall is baffled. Been very sick myself cancer metastasized so know what real pain is. Terrible for these people. Great that you made this video.
When I trained at AW Beattie Technical School, in Allison Park, PA, USA, we were certified to use the radio active source with the "Pig" for the purpose of making film x-rays of reactor vessels, large pipes, huge steel structures, ships and extensive welds. The "Pig" is cheaper and smaller to carry and use than an x-ray machine. As the steel industry, train industry, aircraft industry, and other industries moved away from Pittsburgh, PA, USA, there were no more jobs in quality control for people like me who had trained for them. I have a great education, certification in nuclear metallurgy and non-destructive testing, BS in Biology and Chemistry, and a Masters in Policy, but when I looked around the USA, there were no more jobs for people like me. So, I ended up doing Ocean Rescue, Aquatics Management, and finally became an executive titled "Facility Director" at an Olympic size competitive swimming facility. I lost 20 years of my life when US politicians and corporations sold out the US manufacturing and US working class to foreign labor.
But Stalinki were not terrible. They are still considered one of most preferable houses in Russian cities - Moscow and Saint-Petersburg included. They usually have high ceilings (about 3.5-4 meters vs khrushovkases normal 2.7), thick walls that prevent hearing your neighbours, that make home cozy and warm in winter and chill in summer. And they also had great decorations! Generally they were considered a living for high status people, such as university's professors, engineers and fabric managers. The thing is, stalinki were costly to construct - in measures of time and money. And plenty of people after WWII moved to cities from villages (although it was against the law in that time). They usually lived in wooden barracks and common flats (communalkas), were a family of 4 people usually lived in only one room, sharing wc and kitchen with another 2-10 rooms. Some families even lived in cellars of normal city houses... That is why khrushovkas were invented. And, really, they were promoted as a living only for 30 years, the government promised something else to be constructed afterwards for many families - cause these houses were so chip to construct and were not high-quality or beautiful at all. But still, at that time they were a bless for those living in comunalkas and barracks. [ Hello from Russia, by the way, love your videos! :) ]
There were several types of stalinkas, one was for the elite and other ones for lower ranking individuals or workers. Those were often occupied by several families per apartment or they were dormitory type of apartments. Why do people think that only buildings built for elite during stalin era should be called stalinkas, i have no idea.
@@MRSLAV Have you ever lived in Russia? Because if not, it seems pretty direspectful to argue on a subject you've never even seen with your own eyes, don't you think? I'm not trying to attack your opinion, but after 30 years of living in my home country, it is the first time I read that there were "several types" of stalinkas. They're all generally of one type and, as Margarita mentioned above, they are not the communalkas you're confusing with when talking about common kitchen and WC.
Hey Mr Slav, I don't work in the industry but in modern times these radioactive devices can be used to measure thick materials when xrays aren't enough like oil pipelines and finding cracks in heavy machinary which is too expensive to afford breaking. I'm sure you've heard of the story of Douglas Crofut who is thought to have stolen one of these devices and inflicted himself with a heavy dose of radiation directly from the source like what was found in the walls of Apartment 85. It is thought he did this to commit su1c1de but he died before admitting anything so nobody knows for sure but that is the widely accepted theory. Great video as always :)
I've stay and lived in theses concrete cities. The heating was great because it's from the public water heating and the feature that I loved the most was the heating towels bar in the bathroom.
I work with radioactive stuff and I’m telling you if somehow you lost something like that you better fuckin find it. It shows there was quite a bit of neglect towards the equipment. Stuff like that just doesn’t happen without somebody being neglectful
Surely we learned from the soviets about cutting corners in building stuff and people won't try to steal items or save money. China: pardone? Did you say something?
8:39 haha you fool I have a Geiger counter, but honestly I just got because it seemed fun to measure different background radiation levels for example in a valley or at the top of a mountain
The device Is called a "radiography Machine" And is usually used to shine gamma rays through welds and other joints to measure their quality and safety. Not the first time that happend, look up "Douglas Crowfoot" for example
Ok like...imagine your life rn And your whole family dies like this to what supposedly a curse (?) Everyone around is scared of you and your house You are broken down by all this. And then they say "So you know fam, bad luck! It was all just a mistake😂" I'd went insane right in that moment
I havent heard anyone with a strong as a russian accent as yours, its really cool and intereasting to hear how you pronounce everything! Great videos also!
I have found a few such sources, in my life. I have found a blue metal disk, in some woods, I dropped it immediately, my fingers got numb, I buried it. My fingers are O.K., and have the feeling back.
The Japanese man who died after receiving the largest amount of radiation of any human recorded- so medical staff decided to capitalize on the situation and use him as a teaching example, and the atomic testing videos the military made, showing a soldier standing against a wall, the flash of the explosion, then he walks off screen- Leaving his shadow (and so much more behind) Both are nightmare fuel, if anyone is interested
Builders could not take materials and put stuff inside those wall, because these wall were pre manufactured in a factory and then just put together in a place where they were building the building
Almost all mining quarries and metal receiving sites in the US have some sort of radiation detection device that all vehicles must pass thru when entering .Usually close to or before the scales.Dont know about Soviet sites though.
I remember a man in South Africa that worked in the steel industry, picked up a shiny looking marble and put in his pocket, let's just say, it didn't end well for him or the media , he died and the media lied , nothing new under the sun
Glad to be acquainted mr. Slav. Your in depth storytelling skills are amazing if I must say so myself as an appreciator of a good story. You truly make the most welcoming content for one as new to your channel as I. Here’s to an amazing partnership that takes place in silence between ordinary viewer and content creator 😊
There are 6 people in my house. 1 got thyroid cancer and loads of other stuff she has been fighting. I am slightly autistic and have celiac disease, I also have bad eyesight My 2 brothers have celiac disease and one is very sensitive to injuries and the other has bad eyesight My bigger sister is autistic and my little sister is fine right now but just like everyone else she will probably have something to deal with later. But everything is family genetics and my family just sucks lol🤣🤣
The end made me realize that i would do good living in a abandoned desert rather than even those tiny chances of there being a radioactive material in the walls.....
When i worked in the iron ore and gold mines here in Western Australia the mines had these radioactive devices that technicians used to test equipment with.
a very tragic story... I remember an incident in the USA and Mexico where steel was mixed with radioactive material (not all of it was found, which means that some buildings must still have some in them)
Btw I find it so cool that you managed to learn and speak a totally different alphabet. Idk.. Maybe it's not but I find so 👍 Wish you the better Mr. Slav
4 years ago i went on a trip with firends to sweeden and we visited the HMS smaland, wich later we discovered was sligtly radioactive -_- no idea how the story developed after.
