Radium - Periodic Table of Videos

[thelonelychemist]

0:54  prof ! you have huge hands !

love your videos :)

[TheStevenpo]

this is really helping me in science

[deidarajunior1508]

Best vid from this guy, thus far imo.

[donnyab]

or as we like to call them now down the pub - hot particles!

[Silkie341]

Forever more when I hear the word scientist the image of this man shall be associated with it. This is a good thing as I was searching for information on the element not some music. SCIENCE!

[Mr88kies]

@mutley2209 you cant get a man made element.

[sebasteso1]

@Mr88kies it's not a man made element, it's natural, you can find it in uranium mines

[mutley2209]

where exactly does Radium come from or how is it produced? Is it natural or man-made?

[GVSpitFire]

@mutley2209 you can find very small amounts of it in uranium, it is natural

[Ts6451]

@mutley2209 : Radium exists in small quantities in uranium and thorium ores, as it is a decay product of these. I believe Curie first started to suspect the existence of some unknown radioactive material since her measurements showed that pitchblende(Uraninite) was more radioactive than the uranium could account for. With her husband she did a spectrum analysis on the remnant after extracting uranium, and discovered some, as of late 1898, unknown lines(indicating some unknown element(s))

[Samthebam4044]

@mutley2209 it's a decay product of both Uranium a Thorium metals ,they're radioactive and decay in the environment, as is Radium itself. You find it in nearly every rock , soil, at very low levels. You also find it's decay product Radon in buildings in places like your attic. Radium can cause cancer and a few other things but these take years to develop ,everyone has tces of radium in them. To the naked eye it just looks like a white metal, also glows in the dark when mixed with phosphates

[reseraction]

Thumbs up if you were looking for ravers tunes!

[KarbineKyle]

Radium (Ra) is ~1 MillionX more radioactive than Uranium (U). Americium (Am) is about 3.5X > than Ra. Also, the shorter the half-life, the more radiation is emitted in a shorter period of time. Since U has a long half-life, (U-238 has the longest being ~4.5 billion years), it's not as radioactive a say Ra-226 which has a half-life of 1602 years. Am-241 has a half-life of 432 years. Also, radioactivity plays a big role on how many daughter isotopes there are, the decay modes, and the quantity.

[boxtrap21]

Its the voice of salad fingers!

[OnedayMD]

1:27- Madam Curie's husband did not die from radiation poisoning. Though I don't doubt it wasn't having an effect on him, he was ran over by a carriage and his skull fractured walking across a street in Paris.

[curlymolly70]

I seen this guy on a Wheetos back way back in the day....

[feltonz73]

this will be a wonderful learning experience for my classmates

[TSorovanMHael]

"Because of their levels of radioactivity, [Maria S. Curie's] papers from the 1890s are considered too dangerous to handle. Even her personal cookbook is highly radioactive. They are kept in lead-lined boxes, and those who wish to consult them must wear protective clothing." -Wikipedia

[Convict147]

Did he had an electric shock? His hair looks epic lol

[TheAccuso]

how many people were listening DJradium before that this old man come out from nowhere

[bugea7er]

@TheAccuso exactly

[TheAccuso]

@bugea7er HAHAHA

[weemadtommy]

HOWLY SMOKE IT'S EINSTINE

[JonathanTheAlchemist]

In the 20s, a mixture of ZnS and Ra was used to paint watch dials. 5 employees of the United States Radium Corporation, all female, sued their employers after contracting cancer from the radium in the paint. Yes, it was the employer's fault for not warning them. Radium nowadays has apparently been replaced as cancer treatment by Co-60 and Cs-137.

[vrocked]

Radium use to be used for glow-in-the dark paint

[fuckinmotherbiatsch]

wheres the frenchcore, man ?

[BARONSCHWARZWALD]

In the modern world what is radium used for

[CarnalDiafragma]

We did experiments with Thorium-232 decaying to Radon-228 gas, and it was quite exciting. Radioactivity is always fun, but I've never encountered Radium before.

[Nguli34689]

We used to have Radium watches and clocks when I was a young boy in the 1950's. We also used a piece of this Radium in our cloud chamber experiments to watch alpha particles in CO2. We can't get a hold of Radium anymore, but back then we used to have access to this and Cobalt-60 as well.

[dangerherosandwich]

@Nguli34689 If I recall correctly I came across Cobalt-60 about 4 or 5 years ago, along with Strontium-90 and Americium-241, at a school physics class. But I didn't come across Radium.

[Nguli34689]

@dangerherosandwich We used Radium in class during the 1960s. It's interesting that Co-60 is still around. A cloud-chamber experiment using Radium in CO2 showed alpha particles being emitted from the specimen. It was quite interesting to see. :)

[kalus732142825]

good afro ! :-D

[wauquelin]

Yeah, Bell thought it would destroy tumors. Little did he know it actually created them and destroyed bone. Ppl didn't know what they were messing with back then until it was too late.

[ThiagowwW10]

this guy is einstein wannabe lol

[funkyhunkyhatguylvr7]

i hate this

[mpwelk]

somebody forcing you?

[flatcatbob]

There is a documentary on my home town Ottawa IL,USA called Radium City (1987) and it shows how the whole town is polluted and contaminated by the dial painting company also there are graves and corpses of the woman who painted the dials that are radioactive/waste.

[xxxhannahxzx]

i got this for my science project. it sounds hard :/

[ELFHUNTER50]

if u have radium on ur skin for long enough it will appear as minor burns

[BoatRepairMan]

Great videos! Just to point out, Pierre Curie died from a carriage accident in Paris in 1906 not from radiation.

[theproplady]

Although I've read somewhere that by the time of the accident, Pierre was suffering from a lack of coordination brought on by radiation poisoning, which might have contributed to him being in the accident or his body being weak enough to succumb to it. I guess we'll never know for sure, though...

[sk8erguy552]

@BoatRepairMan From Wikipedia: Only a few months later (After Pierre's Death), on 4 July 1934, Skłodowska-Curie died at the Sancellemoz Sanatorium in Passy, in Haute-Savoie, eastern France, from aplastic anemia, which was almost certainly contracted from exposure to radiation.

[kcalhoun2]

@BoatRepairMan her exposer to radiation weakend her bones

that helped her death

[xxxrrrxxxrrr]

@BoatRepairMan Which was probably caused of loosing attention due to radiation. Let's be honest, it's not a normal thing to being run over by a carriage

[Emman27running]

@BoatRepairMan But it might've been because of his weakness developed by handling radium that he stumbled out into the street and got ran over.

[DuskY1991]

Lol. Carry a glass tube with Radium in your pocket... Hah

Nice video. Good explanation (that's hwy i watch your videos).

[Ununennium119]

How do you actually expect someone to do that? /-|

[Henrync35]

I think prof poliakov has had a haircut because of all the hair related comments on youtube. He's going to be pretty famous thanks to the informative video's

[maekern]

That would be a shame. I think his hair is awesome. He looks rather charming and eccentric.

[ElveeKaye]

NOooooooo! He better not cut his hair! It's so awesome! D:

[bionerd23]

i'm starting to wonder - do you need quite a lot, ie a flask of radium, to burn your skin? or would even a radium painted watchhand burn your skin... if it, say, sticked to a part of your skin for one reason or another?

[kogvos]

Google "radium dial painters" to read many accounts of what happened to the poor women in the early 20th century who painted the radium onto watch dials. To get the brushes to a fine point they licked them. You can probably imagine the consequences...

[bionerd23]

well yeah, if you ingest it, its dangerous without a doubt. but what if its on your skin?

[kogvos]

I don't think that putting a watch hand on your skin would cause any problems, the dust would be dangerous if inhaled and given that the stuff emits alpha, beta and gamma rays and decays into radon gas then it is possible for it to get lodged in the hair follicles and sit there radiating away for years.

[BeigeNinja]

First Post!

Thanks for posting these. They are quite interesting.
