Maria Skłodowska-Curie didnt get sick from her scientific work, she got sick because of her work during WW1, she was doing x-rays to wounded soldiers in a x-ray car that she invented(in that only city hospitals was doing x-rays), thousands of photos with old x-ray machines killed her(old x-ray machines was not properly shielded and also u needed huge ammounts of radiation to make a picture with old photographic plates), so she died as a victim of WW1, she sacrificed her own health to safe life of who knows how many soldiers...

30 years ago I had a radium dial watch that had been made into a broach. It was extremely radioactive. I had to keep it in a lead box. I exposed film in a light proof envelope for less than a second to the face of the watch. After development you could read the numbers and the position of the hands. Exposures longer than one second turned the negative completely black.

[@sammylacks4937]

When Radium was used on watch and clock faces to make hours and hands illuminate in darkness not much was known about radioactivity and dangers of such. A type of paint containing Radium was applied by girls working in clock factories with small brushes. To get the fine lines needed on clock faces they would put the bristles in their mouth using their lips and twirling the brushes to make them point then dipping in luminescent paint and apply to clocks. Each time they put their brush tips in their mouths they also recieved a small amount of Radium that accumulated in their jaw bones. Known later as the Radium girls, sadly all died from radiation poisoning.

it produces radioactive unreactive gas. It is not enough to put it in a lead box. The room fills with radioactive gas, if you have a radium clock somewhere. The gas diffunds through everything.

Talking about radioactive elements we had an accident (level 5 at International Nuclear Event Scale) that happened here in Brazil about 32 years ago. A man found a sealed capsule on an abandoned hospital and took it to his house, after opening it to sell the lead, he found a pretty nice glowing blue substance inside of it and took it to his home. He gave some it to his neighbors, some friends and to some people from his family (including his brother's daughter that ate some of it with eggs accidentally) Some people played with it, giving it to even more people. After some hours in contact with the Caesium the whole family begun to feel sick having all sort of problems caused by the radiation, they didn't knew what could be happening but his wife thought it could be happening because of the weird glowing substance that he found. So, after some time they took the unknown substance to a health surveillance center to ask if it could be the cause of their problems, 'cause everything started after her husband open that sealed capsule. When the technician used his Geiger counter he thought that it was broken because the measure was too high, he borrowed another equipment to measure it again cause he couldn't believe at what he was seeing. To make everything even worse, the government kept everything in secret telling to people it was a gas leakage... Approximately 1000 people were affected by the disaster, the dead people had to be berried on sealed lead coffins and then covered with concrete. It happened at the city of Goiânia-GO at 13th September 1987, the case is known by "O acidente - Césio 137". I don't know if it is interesting to be shown on one of your videos but I think that it could be used as a warning to the people. Consider talking about it when you have the opportunity to show us something about this element.

[@Interestingworld4567]

Yeah anything related to Radiation is bad for our bodies.

[@Schwarzvogel1]

@@Interestingworld4567 Not necessarily. We are bombarded with radiation daily--chances are right now, you are being exposed to radiation through watching this video via WiFi signals. Of course, this is a non-ionizing form of radiation, and thus it won't inflict significant damage on your cells. Even with ionizing radiation, there is a threshold of safe exposure (or at least non-damaging exposure). The unfortunate fools involved in the Goiana accident were exposed to a very high level of ionizing radiation. However, this does not mean that we should fear radiation (ionizing or otherwise) on a pathological level. Personally, I view ionizing radiation as somewhat analogous to fire--unsafe exposure and improper precautions around it can wreak great harm, but when handled properly, it can be quite useful e.g. nuclear power, medical imaging, radiotherapy, and even the tritium-illuminated watch I wear daily. On the topic of self-illuminating devices: if the 'radium girls' had been more circumspect (and if they had been instructed to take proper precautions), I'd be able to have a radium-illuminated watch today that _wouldn't_ cease to glow within 20 years, and that would probably be a lot cheaper. I guess this is why we can't have nice things! (I jest, partially). Of course, there are some radioactive elements and subtances that have no practical use, such as radon. That stuff is just plain nasty--a colourless, odourless, radioactive gas. Since it's a gas, it is perhaps even more dangerous than radium in its solid form, because you can easily breath in radon for it to irradiate your lung tissue.

@@tomparmenter8665 same, i think it is the most radioactive natural metal

[@swabianscience]

It actually does occur naturally, though in traces. It's in the normal decay chain of U-235

[@medexamtoolscom]

Superheavies aren't currently in existence on Earth, they exist only for milliseconds in a particle accelerator at the right times. Thus they are not "on Earth" right now. I believe francium would hold the title of most radioactive metal on Earth. The total amount in all the Earth is probably about 1 ounce, but it's enough that there is definitely guaranteed to be at least 1 atom at any one time. At a half-life of 22 MINUTES, francium has actinium beat by far.

[@swabianscience]

There are always some Isotopes that may be generated momentarily with even shorter half-lives, for example, there's polonium 212 (which, according to Wikipedia, is classified as a metal) in the decay chain of thorium 232 with a half-life of 299ns, but I'm sure in some sidechain there are even shorter-lived elements.

Mike Francis here. (I'm borrowing my friend's phone, LOL).You are my number one go-to guy, for anything Radioactive that I need to know about..... you are arguably, one of the smartest people when it comes to this subject, by far. Anyway, I was wondering if you could do me a favor. About 12 years ago, I was playing with an old smoke detector. Well, needless to say, I put a whole lot of amperage into that thing, via a R/C car battery (7.2vdc@3000ma), trying to blow it up, purposely. It wasn't until playing with it for over an hour, and probably irraidiating myself with a healthy dose of radiation, that I used my tingling hands to flip it over, and to my surprise, it contained americum 241! That is one element I know next to nothing about. It would be wonderful, if you did a video on this, or explain to me the history on this Radioactive element. Also, understanding how applying voltage to the device would create radiation, or enhance the output of radioactive particles from said element. So, thank you my friend, and keep up the excellent work. 😁👍

Remember, the Curies worked with _milligrams_ to _grams_ of freshly prepared Radium compounds! _Millicuries_ to _curies_ in specific activity! 1 gram = 1 curie (37 GBq). 1 milligram = 1 millicurie (37 MBq). 1 microgram = 1 microcurie (37 kBq), etc. 1 Bq (becquerel) = 1 decay/second. Most products still around and available contain _only_ a few hundred nanograms to a few micrograms. Wow, did the Curies work with high activities back then!

You looked through this lens while standing on this machine, and it showed a green glowing x-ray of your bone structure. It wasn't until many people contracted cancer, that they realized what was causing it. I recently watched someone restore one, and I'm very curious to know how the bulb assembly was only radioactive when it was powered up.

Physicist and detector builder here. Actually ZnS:Ag lights up blue. When ZnS is doped with copper instead, it's green and has a longer persistence (and was used in all those green screen CRTs at first). A small warning to collectors of old stuff - radioactive glow paint was used up through WWII on lots of stuff and can be pretty "hot" long after it no longer glows. This is because high energy alpha particles from nuclear decay on the order of mega-electron volts easily decompose the phosphor - ZnS being one example - the chemical bond strength is a single digit number of eV. They're still radioactive, though! My dad had a watch that would set off the safety detectors in nuclear plants from feet away!

@@louistournas120 Aluminium is not safe in your Body :) see connection to Alzheimer desease. universityhealthnews.com/daily/memory/aluminum-linked-to-alzheimers-disease/ Aluminium is great as building materieal but its BS in cooking tools/food.(I think alumiumfoil mostly is safe since its use is non abrassive at low temp and mostly onetime.) The problem with Teflon is that it gases at lower temperatures than the manufacturer claims (~80 degrees instead of 200). www.ewg.org/research/pfcs-global-contaminants/teflon-and-other-non-stick-pans-kill-birds.

This was excellent 👏. Honestly I'd LOVE to hear more about the devices they created to measure all this.

[@thomremo3978]

Can we use this in a nuclear Rector instead of uranium

[@iridium9512]

Technically yes, but only using element's radiation is problematic because you can't turn it off. There's also such a small amount of radium compared to uranium, and also uranium releases more energy.

[@guyteigh3375]

Sadly no - The MAIN issue is that to extract useful amounts of power from a nuclear reactor, you need materials which are FISSILE - that means that you can force them into a chain reaction - which yields HUGE amounts of energy as matter is literally converted to energy. Radium will not do that. Thorium cannot either - but it FERTILE - which means it can be converted by Neutron capture to Uranium via the following method: Th232 +N > Th233 > Pa233 > U233 Uranium 232 IS FISSILE and can be used in a reactor. (Pa = Protactinium)

Brilliant video mate !

[@northernskies86]

Lol there were 226 likes when I clicked on the video. That is the mass number of Radium's most stable isotope. What a coincidence lol can we get 226 likes on this comment as well xD

Your videos are awesome. But you need to enhance your accent. The content of your videos are great, but I always have a hard time to understand half of what you say 😣

[@buntags2621]

Subtitle may do

[@altairlage8783]

Just to let you know, I had no intention to offend anybody. Just a tip to make the channel better

[@starchild7843]

Curie living up in her 60s is pretty impressive, amazing she lived that long after being exposed to that radiation for yrs. Even if she wasn't exposed to it living at that age Unger normal circumstances is impressive. There were not medical marvels of treatment or knowledge of to do or not to do for your health obviously since they were putting that stuff in everything. Pretty much a guessing game of what is or is not good for you. People back then we're playing Russian roulette with their health and lives, and the average person living up to their 60s was an achievement. But thanks to these people who did these things, taking unknown medicine and risks, we now know what not to do. You can say they sacrificed themselves for future generations and not even knowing that they did. We should thank them and say a prayer for these people. I guess that's why always respect the people who go and be a test subject for new medicines and not knowing if it will kill them or not for the sake of others.

Very nice video bro ! Been your subscriber of your quality educational contents in your channel. Sometimes i couldn't hear your voice clearly. I suggest you to put a subtitle thus all of your subscribers can hear your video more clearly. Keep up the good work mate !
