    Metallic lead is not very toxic. You have to ingest it and even then it will typically pass through your system. Melting lead or using solder is not dangerous unless you spend a lot of time with molten lead with no ventilation, and I’m not sure even that would be dangerous as people melt lead and use lead solder all the time in the US. Most lead poisoning is from lead oxide which is a white pigment for paint, which has not been used in the US for over 50 years. Liquid mercury is dangerous only if you are spending a long time in a room where the mercury is open to the air as it gives off a slight vapor that your can inhale. Asbestos is mostly dangerous to smokers, and even then it has to be in a dust form to get into the lungs. The long fibers are not dangerous as you can not inhale them into your lungs. There is a background level of asbestos all over the world because of the natural deposits in many places where the small fibers are picked up by winds. An asbestos rock would not be dangerous to have and handle unless you ground up the fibers into a dust and then inhaled it. Cobalt 60 is radioactive but I don’t think a piece of cobalt bearing rock is radioactive. Cobalt 60 is formed in a nuclear reactor not in a rock from the ground. If you put a Geiger counter next to the radium dial clock you will see it is radioactive but not dangerous for short term exposure. Bring the Geiger counter back about 6” and you’ll see a huge reduction in radioactivity. A foot or two away and your background will be normal. The clock is a point source and it doesn’t take much distance to avoid an increased exposure. You didn’t hurt yourself! I handled mercury as a kid, melted lead for diving weights and muzzle loader bullets, and I wore a radium dial watch in the 1960s and my heath is very good. The watch is stored away from me so there is not danger.

    Hey Tom. I have a bunch of watch hands, alarm clock hands, watches and alarm clocks themselves, vacuum tubes with 2 to 4 mCi of Radium and a Radium check source. All of which are stored in air tight containers in lead pigs or lead lined concrete safes. They are stored in a locked building separate from where I sleep, eat and live. As you can probably tell Radium is my favorite radioactive element. That being said. The Radium watch hands are a real contamination hazard if you remove them from the watch or container they came in. These are no joke.

    Lol, you called them watch "handles" three times or so! But the info is good.... Regarding your statement at 2:17 ... From what I've been told, the glow under black light is not from the Radium itself - but instead from the phosphor which is likely Zinc Sulfide. The reason your old compass no longer has the glow is likely because it is older and the intense alpha activity has literally used up most of the Zinc Sulfide phosphor. Thumbs up for good stuff.

    The glow of the watch hand under the UV light is due to phosphorescence of the phosphor compound used in the radium-226 paint.Or, more likely, from the very thin layer of zinc sulfide probably recently applied to that watch hand to refresh it. That green glow is characteristic of zinc sulfide doped with copper. You can also get a more blue glow which is from zinc sulfide doped with silver. And a yellowish-orange glow from zinc sulfide doped with copper and magnesium. I can't speak to the fluorescence of the radium-226 itself, could that be contributing to the overall light? Maybe, depending on what the concentration of the radium salt itself is in that original paint. The energy emitted from the radium is strong enough to degrade the phosphor in the paint within a few decades of original application so that's why the watch hands and dials don't really glow any more SOLELY from the relatively small amount of total energy from the radium. UV light can help to phosphoresce what's left of the zinc sulfide originally and usually when people resell these on ebay they're "refreshed" with a thin coat of zinc sulfide doped with copper phosphorescent material. Same stuff that's mixed into the plastic of glow in the dark stickers and myriad other products today. Radium-226 was replaced first with Promethium-147 in the luminous paint of that era. Promethium is primarily only a beta emitter so it doesn't degrade the phosphor like radium did. But, the promethium-147 only has a half life of 2.62 years vs 1600 years for radium 226 so the promethium-147 light sources have long since lost almost all of their self-lighting abilities and radioactivity. They still tend to phosphoresce nicely under UV light depending on how they were stored over the years. Tritium gas also causes a phosphor to phosphoresce in watch hands today and those larger tritium vials available. I don't know what the phosphor material itself is in those.

    Radium was one of the most disturbing things that a factory actually sold a lot of, everyone thought it was safe and before you know it dentists were taking pieces of jaw out of the women who worked in the factories. It got so bad that they couldn't walk because their legs or spines would literally snap. The worst part of this is that the company tried to delay the trial because they knew if they could just hold it off a few years then all of the women would be dead, they couldn't even trust their doctors because they were paid off to tell them that they were completely healthy, eventhough they were riddled with tumours. They had holes in their bones, to the extent that doctors said it looked like a sponge.

    I currently keep a radium alarm clock. As soon as I began thinking about the possibility of it having radium, I went down the (glowing) rabbit hole of radiation and bought a Geiger counter (nothing fancy, just a really cheap NR-750). According to it, it's quite hot, 12.6 µSv/h, and to make things worse, the glass was broken and the lume paste in really bad shape (and there is a lot of it). I keep it in a plastic bag, inside another plastic bag, inside a steel plate safe box, which blocks beta radiation and prevents anyone from opening it (the highest measure I got was 5.4 µSv/h). Then took it to the garage my family has in our land, which is ventilated and only opened a couple of times per year to take our tractor in and out. My plan is getting rid of it when I find out how to do it the safest way possible and through the authorities (who doesn't seem to contemplate the chance of an average guy wanting to get rid of radioactive materials, given how scarce the info in their website is)

More recently I found out that this watch gives a reading of 60000CPM through the glass, as measured with an Inspector with a pancake probe (my oldest video shows this watch abut 2 minutes in).

    Yeah that's a bit of CPM. If you wanted to figure out an actual gamma exposure rate you could make a simple filter of 3mm (1/8") thick aluminum sheet metal ($5 on ebay) and re-measure the CPM for a ballpark mR/hr rating. After you filter that CPM the conversion rate is approximately 3500 CPM per mR per Hour. It will be a much smaller amount of CPM after filter. And these are only some rough ballpark numbers because it's not calibrated for that isotope, but better than nothing. Our hands and extremities are pretty resistant to the rads so you really have nothing to worry about. Still, it's interesting stuff!

    The NRC has an occupational yearly limit shallow-dose equivalent of 50 R (0.5 Sv) to the skin of the whole body or to the extremities, which is huge compared to this stuff. (10 CFR, Subpart C, 20.1201) I once knew a fellow who worked as a radiochemist preparing O-18 "FDG" for PET scans that got that much every year to his hands. He stood behind a shield of leaded glass while doing the syntheses (by reaching around the shield with his hands) to lessen the does to the rest of his body.

I have switches, hands, military instruments, etc. The hottest gives me > 1 mSv/h (sealed). But, I used a Terra-P dosimeter. They're sealed. I keep them in glass boxes and in lead-lined boxes (labeled). They peg my CD V-700 6A (beta shield open). I'm guessing the turn & slip instrument could give ~ 2 mSv/h (unshielded). I do not open them! But, I also need better equipment I can't afford . . .

    Interesting video. Just to note two things. First, I wouldn't expect an appreciable reduction in radiation intensity from radium, as it has a half-life of 1600 years. The phosphor in radium paint often broke down over time, but the radium remained. Also, point 2, radium was discovered by Pierre and his research student Marie and both shared the Nobel Prize.

    Radium was discovered by Marie Sklodowska Curie, a Polish chemist, and Pierre Curie, a French chemist, in 1898. Marie Curie obtained radium from pitchblende, a material that contains uranium, after noticing that unrefined pitchblende was more radioactive than the uranium that was separated from it. She reasoned that pitchblende must contain at least one other radioactive element

    its not the glow of the radium that you see ; but the glow of the zinc sulfide dopped whith cuprid chlorid (ZnS(Cu)) ; the radium 's alpha particules excite the ZnS like in a spinthariscope and produces the glow! The glow of the radium described and shown in Marie curies photo is due to the high concentration of radium (2g pure radium!) and the ionisation if the nitrogen of the air around in the cup!

    That compass may have used radium 228 which had a half life of like 5 years. Radium 228, or mesothorium 1, was used to cut the longer lasting radium 226 to help cut costs in making luminous dials at the expense that the dials wouldn't glow for nearly as long.

    during the 1st world war folks mixed the two 50/50, with mesothorium having a half life of 6 years compared to Radium's half life of 1600. Promethium 147 started being used in the 60s and is still being used today. Another one used today is tritium. "U.S. RADIUM CORPORATION HAERNo.NJ-121 In 1957, C.W. Wallhausen, then vice president of the U.S. Radium Corporation, wrote to Dr. Marinelli, Associate Director of the Radiological Physics Division at the Argonne National Laboratory: "I know that radium and mesothorium, as well as in some cases, radiothorium, were used in these paints, and the proportions were not by any means uniform from batch to batch, since it seemed to be standard practice to use whatever material was most readily available, and in many cases, used some unusual mixtures" (Wallhausen 1957). A related memo from Dr. Robley T. Evans (1966) of the Massachusetts Institute of Technology, based on a telephone conversation with Wallhausen, records that: Wallhausen says that he has no records of any sort left from the old days. They are all in the file he gave to Marinelli. He has nowhere to look for the composition of paint sold to Waterbmy Clock Company in 1926, 1927, and later. All of the people involved in the company at that time are either dead, in their late 70s, or out oftheir minds.... Barker would just mix whatever he had around the place and sell it, 50-50 or 10 percent Myth and 90 percent Ra, or whatever." - U.S. Radium Corporation historical and descriptive data, page 29-30- cdn.loc.gov/master/pnp/habshaer/nj/nj1600/nj1643/data/nj1643data.pdf

    At about 2:20 onward he clearly says that the black light shows a glow from the Rsdium, and I believe this is incorrect. The glow under black light is from the Zinc Sulphide. Although there are Uranium compounds that fluoresce, and thus glow under black light, I can not find any reference to Radium compounds fluorescing. His wording would lead to confusion over what the black light is doing, which would cause that green glow, even if, 1,000s of years later, all the Radium had essentially totally decayed away.

It's not entirely accurate, since it's calibrated to Cs-137, but it's enough to easily saturate (overflow) my Inspector USB ( > 360,000 CPM). I just keep this source sealed inside the rare unit it came in, since it's sealed very well there. I was very careful, and surveyed the area I was working in with another pancake G-M detector. No (or undetectable) contamination was detected.

Readily reacts with nitrogen rather than oxygen on exposure to air forming a black surface layer of radium nitride. All Isotopes of Radium are highly radioactive with the most stable isotope being radium 226. Which has a 1/2 life of 1600 years. And decays into radium gas or specifically isotope 222 when Radium decays Ionizing radiation is a product which can Excite Feresique chemicals and cause radio luminescence .

    Only those workers that PUT THE RADIOACTIVE PAINT IN THEIR MOUTHS were SICKENED, or died even, from this work. The vile plant owners and managers took careful steps to protect themselves! I owned a radium dial watch for about 20 years! (Untill it was STOLEN!) And I'm just fine.

    Radium does NOT glow....at all. The phosphor in the paint glows when the gamma and alpha particles are absorbed by it and then are re-emitted as lower energy visible light.

    this is not the glow of radium : the radium salt (radium nitrate most of the time) was mixed with ZnS(cu) and when you lit up the hand dial with UV photons that's the fluorescence of ZnS(cu) that you see. The alpha particules from the radium nitrate excite the ZnS and make it glow in the dark.

    Bit overly cautious if you're recommending not wearing a radium watch all the time when the dose you'd get from it, as shown on the device, was so negligible you couldn't tell the background radiation from the radium.

    If you check the wikipedia article about radium isotopes, you will find out that it has many isotopes, all of which are radioactive. the longest-lived isotope has a half-life of 1600 years, but others have much shorter half-lives. See the article for more details.

    If its alpha particles, the radiation isn't even going to go thru the cloth to get out of your pocket. Now, ingesting it would be a different matter, since the alphas will get to your body's cells in that case.

    It is correct that the alpha is easily blocked by the metal or glass dial but there's a pretty decent portion of Gamma too. I've seen it many times on my gamma only dosimeter (Canberra MiniRadiac). Tom mentions this may be from the later isotopes in the decay chain. Maybe even some beta in there - I'm not sure. It takes a full three mm thickness of aluminum to block soft beta. Glass is a pretty decent blocker for beta too. www.ld-didactic.de/software/524221en/Content/Appendix/Ra226Series.htm

    The gammas will typically be peaks for some lead, bismuth, protactinium and bismuth daughters, and a peak at ~186 keV for Ra-226.

    Did anyone read the scientific paper which looked into every radium girl and the effects? The exec summary was amazed at how little damage so much radium had caused to most of the workers. We really do not understand how the body actually responds still. Particularly hormesis. People are too often captured by fear of the unknown.

    "The Radium Girls were female factory workers who contracted radiation poisoning from painting watch dials with self-luminous paint at the United States Radium factory in Orange, New Jersey, around 1917. The women, who had been TOLD THE PAINT WAS HARMLESS, ingested deadly amounts of radium by licking their paintbrushes to give them a fine point; some also painted their fingernails, face, and teeth with the glowing substance." en.wikipedia.org/wiki/Radium_Girls

    I did get Radium on my hands once. I found a tin full of watch hands in a bag full of old watch parts. I had enough sense to put down an old plastic table cloth, but I didn't wear disposable gloves. The tin pegged the Gc I borrowed at the time, and I still got readings on my hands even after washing them several times -- scary stuff. I turned the tin over to our local university radiation safety officer. His only concern was I transported it in my car. I thought it odd since the watch parts were originally mailed to me, and god only knows where they were and who handled them before that.

    Cassi O I actually visited the Radium Dial Painter site in Orange NJ in 1980. The site has 7 distinct structures on it. 5 of the 7 buildings show elevated gamma ray exposure rates. 2 appear as just having normal background levels. I FIND IT INTERESTING that the offices where the management worked, happen to be the 2 offices where only background radiation levels were recorded. That is according to a May 1979 New Jersey Dept. of Environmental protection report. They knew damn well that Radium was a danger and protected themselves but not their workers. The state radiation survey of the levels in the buildings seems to back that contention.
