Next video is an iOpteron CubePro tracking mount unboxing/use lol Who want's to photograph galaxies, comets, and nebulea?!

I used to do astroimaging, but I had to give it up -- I'm too old to lug around those heavy tracking mounts, etc. I thought I'd stop before I injured my back, rather than just afterward

Happy New Year Tom thanks for making such interesting videos. It's fun to geek out about gamma spectroscopy with you through KZread.

I thought I was the only one with cats and radioactivity at the top of my cool list.

Nope!

First video of 2017 & another great video!

quite enjoyed this one. happy new year from switzerland!

Great Video

Speaking of radium if you take a look on ebay you can find a good number of cheap WWII era aircraft switches with a radium tip (easily recognizable in the listing pictures). I think it's a really nice item to have in a collection of radioactive things.

I've been standing here waiting mr postman :)

Happy New Year, Tom! Cool video! I have a Phinney-Walker alarm made in Germany! The hands and numbers looked very similar! Glad I checked, thanks to you! Mind is a plastic box. It has two side compartments for cards or cigarettes (or anything). It's about the same activity. If the Radium paint is dark brownish, and doesn't glow under UV well, it's usually pretty hot! I think I know what the uranium minerals are. If I had to venture a guess, I'd say it's gummite (dark orange) and carnotite (canary yellow). Maybe some uranophane, too. I like these radioactive mystery videos! Thanks! Keep up the good work! I like it!

Thanks! It is a nifty clock! I think you are correct about the uranium, BTW

Is this how they kept atomic time in the good old days ? Thank you for the video ! tjl

Short of buying my own counter, is there any other way to find if a clock is radioactive, it's fairly old, but the glow seems to be negligible unless charged by light, so beginning to think it isn't. I seem to recall on old radioluminous stuff, it's the phosphor that packs up, rather than the source

Can't believe those poor Dial Painter Girls used to lick the Radium coated brushes!

Why would the temperature change affect the background count?

Hi, maybe you can help me? I'm want to buy such sample disks from Spectrum Techniques. Since i live in Switzerland i have to stay with rather short-lived isotopes (because they will decay within a few yeas to "not considered radioactive" and can be disposed legally). My main purpose for them is to make a test of a lot of geiger tubes and write a rewiew about the tubes. So for Alpha i would purchase Po210. For Beta my only option would be 1uCi of Tl-204... For gamma i only can use Co-57, but i could purchease up to 100uCi of that. Do you think these isotopes are a good choice for testing GM tubes?

I have mantles, but they are far from giving many counts, on a LND-712 it goes only to 5000CPM, Am-241 from a smoke detector goes up to 100k CPM

I want a geiger-counter so bad! But I've got no money...

Hey antiprotons, I need your help. How do I handle with radioactive materials, where do I put them or anything. I don't have any professional equipment, so I'm asking you how to handle americium from the smoke detectors?

Am241 from a smoke detector? Don't remove it from the detector. It can be dangerous if it gets loose. I only own exempt sources (too weak to be regulated). Basically, the type a school instructor would use. They can be stored in a room where people don't sleep or work, such as a garage. For anything beyond exempt sources, you would want to speak to speak with a professional for safe handling.

I know, I won't remove it from it's casing, I just want to enlarge my collection of radioactive elements. But I don't know how to handle with americium. I was thinking about putting it into one of those "kinda like tube" containers made out of lead. But it is primarily alpha emitter, and here I'm confused. If it is an alpha emitter, then it will be stopped by our skin. Of course I'll wear gloves, like to every element that I have, I'm not about to ingest it. And I didn't buy normal smoke detector, only the casing that contains americium. It was 2.80$ for 0.9uCi on the AliExpress, the shipping was free.

I have a radium westclox model 15108 that gives a reading of almost 3000 CPM

Are the gloves because you were concerned about dust from the Radium?

I recently found out it was the polonium in cigarettes that causes cancer. Do you have any way to measure the polonium in a sample of standard cigarettes and compare it to the polonium level of e-cigarette nicotine juice? I am trying to get my family and friends to quit and think that would help convince them. Keep up the good work in 2017.

It's not the polonium that kills. Its all the crap combined... Having tar clog your lungs, hindering the coughing reflexes makes all the other nasty stuff non-smokers cough/breathe out getting stuck instead. Asbestos and radon gas and regular fine dust etc is much worse for smokers because of tar(ish) lungs. Measuring polonium in nicotine wont change that.

I was reading a few studies about phosphate fertilizer containing polonium and that most plants don’t absorb it but tobacco does. Also, being an alpha emitter, it’s fine externally but terrible inhaled. It would be great to test cigarette tobacco on the spectrometer and compare it to organic tobacco that was fertilized without mined phosphate fertilizer.

How do you normally get rid of or clean your gloves and other contaminated items and equipment?

Trash. They are not hot. These are all exempt sources. I actually called the NRC and asked them about this stuff. They said, toss in the trash. I argued with them, but that was their advice lol

antiprotons You cant trust anything the NRC or anyone corporately linked to the Nuclear weapons or power industry. the fact that they totally ignore internal exposure to radiation says it all. The health risk model deployed globally is based upon external radiation exposure reliant on data obtained from the Hiroshima and Nagasaki bombings in 1945. Absorption of radionuclides through the skin, ingested or inhaled generates a completely different health risk profile to the standard external radiation health risk model. (since the 1969s Uranium for example has been known to directly couple to DNA strands causing genetic damage - and yet it appears that depleted Uranium is fine to use as a penetrative tipping material in various military projectiles such as missiles and armaments. You some very interesting videos but most o the sample you use in your demonstrations should be handled with care and dispose of even more carefully. (check out the KiKK study in Germany which looked at the increase in cancer for child populations living near German nuclear power stations - a study repeated by the French in their nuclear power industry that found similar increases in cancer rate. I realise that you may enjoy the work you do, but imo the nuclear sectors are perhaps the most irresponsible and insane activities humans have every engaged in)

Go polimaster! Go!

With all the recently renewed hysteria over the continuing Fukushima disaster and increasing levels of radioactive materials being released and die-offs in the Pacific, would you please do a video measuring levels and/or types of radiation in common seafood, like tuna, salmon, oyster, and shrimp, etc? Please show us whether seafood is safe in 2017. Thanks.

11:11 "I ???? obsidian fragments" didn't get that.

Have you ever been sick from radiation poisoning?
