In Australia, we are allowed to put no more than 10 radioactive smoke alarms in our bin at once. If we have more than 10, we have to treat them as radioactive waste, or alternatively put the excess units in a different bin. There is no limit when placing them in a neighbour's bin.

What's really interesting is when you rip one open but keep it powered, and then put an oscilloscope on the output of the detector section. You can literally see the voltage levels drop as air gets more and more blocked by particles like smoke. That in itself isn't particularly astonishing, but then when you think of that crazy shower of particles flying off the Am241 sample getting interrupted by teeny tiny bits of carbon in the air causing a high voltage ionized air path to disrupt... Yeah... it's just totally cool. :-)

I recently got some old radium watch hands, and a small sample of ThO2 for my element collection. The watch hands don't glow brightly, but if I let my eyes adapt to the dark for an hour, I can see the super dim glow, with crazy sparkling all over. For the ThO2, I bought a ZnS(Ag) screen to place on top, and it is also a super dim and sparkly light show. This is another cool way to visualize alpha radiation, although it is unfortunately difficult to capture on camera.

Very good! I couldn't wait until you would upload. I watched in Russian first because of being very impatient. Your chemistry videos are excellent. 👋 from 🇨🇿

I'm incredibly fortunate to have toured the 'back end' of the TRIUMF Research Particle Accelerator at UBC. When I toured I was in an area that was still contaminated with radioactive oxygen which had blown about. They had mostly cleaned up however you could also see black smudges of contaminated Carbon on the ventilation system. That's what you can do with a chem degree and a girlfriend whose father worked there for 20 years. :D (I didn't get a job when I applied, sad)

your videos are so well explained and produced. I can see you put lots of work into each one. I'm really grateful for your work!

Waiting for you to complete your playlist on Elements.🙏🤩

Great video. Lots of important information! I've been wanting to see a video on this subject for a long time.

I came to know about application of Americium during a project. Americium was used there to determine thickness of the metal sheet. It was amazing to know how the radioactive property is used to determine metal thickness. Your videos are really informative and useful. Thank you.

This was fascinating! I saw my first cloud chamber on TV back in the very early 60's on a Mr. Science type show. My whole life I have wanted my own cloud chamber, and yours looks quite attainable. Thanks for the facility tour, also. I've wondered what happens to old smoke detectors. A truly wonderful science channel.

You’re the one that got me into chemistry, I had zero interest in this subject since I only cared about physics but you’ve sparked something big in me. Thank you for all that you do, I hope you make a lot of money off these videos.

I went to Griffith Observatory today. They have an exhibit there that showed something I had never seen before that really intrigued me. It showed a cloud chamber and a spark chamber detector and they were being used to detect secondary cosmic rays. And then I come across this video later today purely by coincidence that showcased the same type of cloud chamber and the spark chamber detector. I don't know what to think now...

Truly amazing video. You always make great videos, but this was exceptional. Keep up the good work.

If you open a source chamber on a smoke detector stop when you see the tiny piece of gold. The Source is safe to handle at this point. It is still in a protective and shielded container with only the one window. The ionization chamber (cover) makes a great cap to control radiation. I always store mine above head level pointing upwards. Alpha radiation is used industrially to control static. I used to play with a source used during newspaper printing to control static cling.

If I'm not mistaken, also, alpha particle emission takes place over a range of energies depending on several factors so some can penetrate paper. (Also the type of paper is a factor too)

Happy to see new element videos :)

It would be ironic if the only reason some facilities were top secret in the past was because the officials didn't want the world to see how irresponsible dangerous materials were being handled.

What to do with Americium, take #2: 1)Get a bunch of ionising chamber detectors. Scrape off the gold layer. If Am²O³ stays on the plate, skip to step 4). 2)Seperate Am²O³ from gold by dissolving it in a drop of acetic acid or melting off the gold. 3)Reduce Am (|||) from oxygen, turn it into hydroxide or just heat it to dry out. 4)Dissolve it in small drop of acetic acid, then in diluted citric acid and put in the syringe with a long, strong needle. 5)Travel to Altai Pukin',s unofficial castle residence. Find his favourite wine or other sour beverage. Bribe the distributors of this beverage to let you deliver them. Lace the bottles with Americium by injecting it equally trough corks. 5)Sit back, and enjoy the irony..

To be honest, I wasn't expecting a whole lot from this video. It's in smoke alarms...what else can you talk about?? But it turned out to be one of the most interesting and favorite videos from you! I've seen Cloud Chambers before, but have never made one...I need to try this! That was fascinating seeing the atomic particles shooting thru the mist vapor! Thanks so much for such a cool presentation.

Seriously, this is attracting such attention it cannot be just skipped by

I have also taken the button out of a smoke detector to do experiments with orchids and cacti. You can glue the button to a copper wire and position it on the flower of a plant to try and create new breeds. Radiation breaks apart the DNA in exposed pollen when you are fertilizing manually with a paint brush so the seed that forms can be a mutant plant. Most are infertile or die after germination but I've created a few new orchids that have leaves that grow like a corkscrew. Pretty neat.

Thanks for the video.

Great video as usual, but I have to contest one important thing. 9:15 - 60 keV X-rays (or gamma technically in this case) definitely aren't "safe". The TVL of soft tissue to 60 keV photons is like 11-12 cm/~4.5". Basically, 1/2 will penetrate at least 3.5cm/1.5", and 90-99+% will be absorbed by the body, and they are definitely highly ionizing in tissue. At 4uSv/hr, at that distance, you'd probably have to wave that thing over someone for a year in order to generate enough to make a single chest x-ray, so I'm not suggesting that it's dangerous to handle, but yeah, 60 keV is right in the middle of the range that penetrates enough to damage tissue, but not enough to pass right through. If you generate enough 60keV photons you basically have a perfect x-ray machine.

@@Ripen3 It isn't likely to cause any harm at those levels. That's why I said it's not unsafe - quantity-wise. The quality/energy level of the radiation, however shouldn't be characterized that way. It's probably irrelevant to 99.9% of people in any situation they are likely to even encounter. Just that, to say 60 keV photon radiation is harmless is exactly the opposite of true. It gets slightly complicated... For radiation safety guidelines we use a linear non-threshold model. That means we take levels with known harmful effects and assume that, for instance, 1/1000th of that is 1/1000th as harmful. We know that's not true based on epidemiological data that we have - low levels up to a few 10's of times normal background *may* even be slightly beneficial - but it's the standard practice for regulatory purposes to assume "no safe dose". Also, If you ate it 🙄, kept it near your eye for a long time, or carried it in your pocket every day... You might increase risk of cancer, cataracts, or fertility issues respectively. Honestly probably still not, but having no respect for it isn't a good approach is all I'm saying. Or if you got 1000 of them and tried to extract the Am (someone did that) - that'd be dangerous. It's hard to communicate radiation health physics effectively. That's why everyone is (wrongly) afraid of nuclear power.

Very nice, thank you.
