Cobalt 60 has a half life of 5.3 years. Doing some arithmetic, that comes out to about 30 TBq/g, or 811 Ci/g. For reference, Radium-226 is defined to be 1 Ci/g. That sample is 10^-6 Ci (1 uCi). Dividing it our, you get a quantity of 1.233*10^-9 grams, or 1.23 nanograms of Cobalt-60. For reference, an average grain of sand weighs about 15 micrograms. The quantity of Cobalt-60 there is 4 orders of magnitude (10,000x) less than a grain of sand.

[@DreadEnder]

Yeah it’s absolutely ridiculous stuff. You have nuclear fusion fuel like uranium which is very radioactive, then you have nuclear bomb fuel like plutonium-239 which is extremely radioactive, then you have RTG fuel like plutonium-238 which is ridiculously radioactive, then you have radiotherapy fuel like cobalt 60 which is ludicrously radioactive! For context the shorter the half life the more deadly and radioactive the isotope. Uranium-238: 4,500,000,000 years Plutonium-239: 24,100 years Plutonium-238: 87.7 years Then the heaviest element oganesson: 890 nanoseconds. Cobalt-60: 5.27 years

How do you do the calculation between half life and radioactivity per unit of mass?

[@zacharytaylor190]

​@@dario110011 To find specific activity, you take the fact that the sample will decay half of its mass in that time. You assume a 1 gram sample. Therefore, 0.5g will have decayed. Cobalt-60 has an atomic mass of 60g/mol, so you can use avagadro's number to find the number of atoms decayed, which would be the number of decays by definition. You know that 1Bq is 1 decay per second.

Nuclear engineering grad here. Decided to do some rough calculations to get an idea of dose rate in this video. Assuming a 1 microcurie point source located exactly at the center of the disk & no photon attenuation (for simplicity), the uncollided fluence will be ~2.3e5 photons/cm^2*s at the closest point on the surface of the cylinder. Note that Co-60 emits just under two photons per average decay (@ 1173 & 1332.5 eV). The shallow dose response function for the average of these two energies after interpolation from ICRP 1987 data is about 6.42 10^-12 Sv cm^2, which multiplying into the max fluence gives 1.476 microsieverts per second (0.1476 mrem/s). Thankfully our host held it from the furthest point on the puck, which instead gives a fluence of 3651 and a dose of only 0.00234 mrem/s or 8.43 mrem/hr. This is certainly not something you want to be touching for very long, but what was shown in the video was not very dangerous. (Legal annual limits are often on the order of 100 mrem) I am in no way an expert in dosimetry and likely made some incorrect assumptions, but I erred on the side of calculating a higher dose rate rather than a lower one. The sample dimensions of 3.2x25.4mm were obtained from the Spectrum Techniques website.

[@livingperiodictable]

Thank you for that thorough, in depth analysis!

[@Im_felix39]

Here's some info about the tube version. The "drop it and run" instruction is a safety recommendation for dealing with a radioactive cobalt-60 (Co-60) source that emits intense gamma rays. The instruction is to immediately run away from the source, which can be about 10 cm long and 2.5 cm in diameter. If you can, you should also try to shield any organisms that might be nearby. If you're close enough to a Co-60 source to read the words on it, you could be in serious danger. For example, standing 1 meter away from the source for about five minutes could give you a 50% chance of dying within a couple of months. Even if you're farther away, you could still be injured if your hands or other parts of your body are close to the source.

[@jimthompson4678]

my chem teacher in HS had a display of the Periodic Table like that. all radioactive elements were simulated with non-radioactive samples. having anything that hot. if it actually is a sample of Co-60 outside of a properly equipped lab i would be worried.

[@Hoellenmann]

His sample is so weak you could literally eat it, and the plastic container would probably do more harm than the Co-60. 1 uCi is basically nothing in terms of dose you would get from it.

[@tylergartner4069]

​@@Hoellenmann 1 uCi of cobalt 60 is the maximum permissable body exposure amount, 54 uCi is the annual limit of intake before risks arise. While 1 uCi is a small dose I wouldn't recommend keeping it in your pocket or close by where you spend time. Even these small 1uCi sources are recommended by the manufacturer to be handled for 2 minutes or less, never to handle with your hands but long tongs, to store them 2 meters or more form any area people spend extended time and to store in a lead lined container. This information comes directly from the handling and storage section of the standard procedure documents for these samples

[@Hoellenmann]

@@tylergartner4069 yes ok it was stupid to say that without checking what the radio toxicity is, but I imagine it to be the value for a water-soluble salt of Co60 or already a solution. The plastic disc with the cobalt would pass right through and do almost no harm given it is water proof, compared to like ⁶⁰CoCl2 which would get absorbed into the bloodstream

[@Hoellenmann]

@@tylergartner4069 I sometime move 1-3Ci sources of ¹⁷⁷Lu, with just nitrile gloves from one lead container into an other. Not often maybe one or twice a year. But when I did that in june this year I got like 4mSv on my finger ring dosimeter, in place of just 1mSv/month more often than not. And ¹⁷⁷Lu has a very similar beta energy, I think ~.5 MeV compared to the .317MeV beta from ⁶⁰Co, but Co has about 5x more gamma energy. So the Lu cooks your hand by breaking radiation and the Co by self generated gammas. Don't worry, the hand is still there and healthy XD

[@Born2Losenot2win]

I just had the privilege of working with Cobalt 60 these past two weeks for my gamma ray spectroscopy lab

[@40hup]

The problem with "collecting" Cobalt60 (besides the safe handling and storage - it is an aggressive gamma emitter) is that its half-life is only a good 5 years, so in 15-20 years it will be a very weak source - but probably still okay if you just want to show its spectral line on a scintillator.

[@timgunnell5045]

That level of cpm is equivalent to 50 times the annual radiation exposure for the US average. Or equivalent to about 30 full body cat scans in a year. Math below: 1080cpm is roughly 1mrem/hr. 3900 cpm = 3.6mrem/hr. Annual radiation average for US is 620 mrem. Annual mrem given off of sample in video is 31,600.

[@runcycleskixc]

Yes, if one is silly enough to walk with that disk in their pocket for a year.

[@VerminWolf]

Also if the packaging it was wrapped in is correct. It's dosage rate is less than 0.5 mrem/hr. Which i'm going to assume they did their math and checked it twice because if not that's an lawsuit waiting to happen. the counter he's using may broadly check for all radiation types and not just ionizing radiation which might be were your higher dose number comes from.

[@Hoellenmann]

@@VerminWolf They didn't calculate it, they measured it. And it's the surface dose for shipping. How high the surface dose rate is determines the activity category of the package.

[@FaustoTheBoozehound]

Counts per minute cannot be directly related to dose rate unless you've calibrated the instrument to that isotope or know the efficiency of the detector at the subject nuclide's energy and apply a factor. His instrument is likely calibrated to Cesium or a mixed nuclide source, not cobalt.

[@bobspalding2477]

Yeah…no. Tragically misguided logic there. One: no one is putting this sample in their pocket all day, all year. Second and far more important: holy hell a couple thousand CPM isn’t even close to a mREM. “But how do you know this, Bob?” I’m a radiation Protection tech and calibrate our instruments. The general conversion from DPM to mR is 5million DPM to 1mR…..so 500k CPM. Depending on the instrument, efficiency, and type of radiation. So basically, 3k isn’t significant, certainly not the equivalent of an X-ray/CT scan (which is acute dose to begin with) And as always, use the linear no threshold model and don’t keep radioactive shit in your pocket 👍 time distance shielding children.

Based on what I'm reading in the Safety Data Sheet. The sample he has is probably very small. It's stamped with 1 uCi. For cobalt 60 this is C-level hazard (low hazard). Even a sample marked 100 uCi would be a C-level hazard. If he were to ingest this sample maximum permissible body burden (MPBB) is 1.0 uCi, based on Stanford Guideline of whole body dose not exceeding 500 mRem/yr. His body would metabolize it effectively cutting the half life from 5 years to effectively 10 days. So my bet is he could eat this without any problems let alone handle it and display it. But luckily we're on the internet, where the best way to get the correct answer is to give the wrong answer and be corrected!

CPM doesn't necessarily equate to R/hr. You should get a calibrated dose rate meter like a Bicron Microrem. There is a pretty good rule of thumb for Co-60 that says 1 Ci = 1 Rem/hr @ 1 meter. So, 1 uCi should equal 1 uRem/hr at 1 meter. Around here, normal background dose rates are about 10 uRem/hr General Area. I did some math, and I think your source should be about 1.5 mRem/hr On Contact. That's pretty tame, but I'd be interested to see what a dose rate meter would read.

I do know that the small rods they use for radio therapy are extremely dangerous, with guaranteed lethal exposure taking 10 minutes at most, and even 5 minutes being a 50/50 even with prompt medical attention.

After you get 6 ft away from the sample, it becomes undetectable. I have a few pieces that hit 10k CPM on that counter, and after I get around 1 ft away, it drops to 600-1k CPM.

I definitely wouldn’t want to be in the same room as it all the time, but I agree that it is largely unnoticeable at a distance of a couple meters away. One thing to note is that Co-60 undergoes beta decay, which emits photons (two photons at around 1200 ev for Co-60). These are gamma (high energy) photons but still the same thing as light. Gamma photons pass through most matter but do still attenuate, so you can essentially think of them as traveling through a world of glass that gets cloudier the denser a material is. Unfortunately, a little plastic case and some air do little to stop it.

@@FlamingZombie567 A thought, it is a bit sad that they did not make the container clear on one side... But... My biggest concern with owning this, would be it getting out of the container somehow. I am sure they are made tough, but should it get out, it could find its way somewhere you don't want it. (I can imagine a situation where someone somehow loses track of it, and it getting tossed in the garbage or somewhere, it's not just you that needs to worry about it, it is those that come after without benefit of your guidance) The worst form of exposure to radioactive elements, especially ones that produce energies as high as this stuff... Is internal exposure. Even fairly weak radioactive materials, that are blocked by simple materials, can do a lot of damage to your cells, if you get it inside of you. For the most part, I am not overly concerned with radiation. I believe that a well thought out nuclear power infrastructure would be the best choice for the immediate future. There are ways to properly store the waste material safely. A tightly regulated transportation system for moving the material from on site, to the waste storage locations, would help reduce the potential for incidents to very low. Its not like we need to transport huge amounts of it at once, so even an accident could be limited in scope of impact and cleanup. The thing holding us back the most is the general misunderstanding of nuclear power and the waste products, and the safe storage of those materials. We have plans to build safe storage far underground, but the public freaks out about it, wherever we announce the plan. "Not in our backyard" they cry... Meanwhile we are forced to store the material on site of the facilities, and that is the least safe way.

@@marine6680orphan sources are definitely scary. Thankfully, Co-60 is relatively short lived, but accidental ingestion or misuse is still a dangerous possibility even after multiple decades. I recently graduated with a bachelors in nuclear engineering and definitely agree on your thoughts for the power industry. It seems like a great course of action to phase out fossil fuels with nuclear now, and build up renewables alongside it to eventually meet further demands as it and battery technology improve. Also, some perspective from an insider, the economics is just as much a problem as fear right now. Some of the costs are indeed driven by public fear, but nonetheless, investors are not all that willing to fund projects which only start getting returns 20, 30, or 40 years in the future and have a risk of being shut down before then... At least, that's the main thing stopping expansion right now imo

Maybe a dumb question, but how can you handle having that in your house and it not killing you?

[@Mr.Fox.92]

When it comes to radiation , the amount of an element is more important than the element itself. He's got small, small amount there, therefore it is not dangerous and the average person can even buy one of these since low amounts like this are exempt from regulation.

[@makeupandmusicgirl]

@@Mr.Fox.92 thank you! I read a book about radiation poisoning recently so I was confused because it made it seem like even the tiniest bit would kill you.

[@Mr.Fox.92]

@@makeupandmusicgirl Tiniest amount can kill you but it totally depends on what type and if it's ingested or not. There's a lot of factors at play

flip it and get 2x more, that geiger is fairly insensitive too

[@40hup]

I doubt that, as Co60 decay emits some high energy beta, but mainly gamma - you would probably be right for an alpha-source, or if it were a metal disc for a beta source.

[@ramennoodles7221]

@@40hup Well, the fact that is is closer to the source when flipped it’s guaranteed you’ll get more activity due to the inverse square law, but maybe it won’t be 2x more

[@40hup]

@@ramennoodles7221 This disc is about 2mm thick, and the Co60 is in a 1mm pit in the middle of the disc sealed with some resin and a sticker on it - so however you flip this, the GC tube has the same distance to it, the only question ist if 1mm pet-plastic (or whatever) does seal more gamma or 1mm resin - which, in reality would be hard to measure with a hobby GC anyway...

These are stored in lead pigs away from where we are on a regular basis. Risk is low due to the low dose given while filming.

@@livingperiodictableGlad to hear you’re not hanging out in the same room with it all the time. It’s not very dangerous with occasional exposure, but your annual dose would definitely add up if you were sleeping next to it lol

Im glad we can order highly radioactive material straight through the mail, but if your rifle barrel is .5 inches too short, you could get the max of 10 years in prison. What if i, say, ordered a few and a couple of other people i know order a few. What could be done with all that,hmmm.

Nothing. You would need to spend well over 100k to get a dangerous amount.
