Enother interesting information: specially for you.

- What do you think about this? see, and tell us now.
- Never considered spectroscopy would be as accessible to so many people ... I guess since the setups we have for purity verification cost more than I would ever want to pay for one :) ... but soundcard interface ... seems weird to me... anyhow.. so much of this sounds familiar... trying to explain to techs why all those peaks show up, and no they really are not extremely rare isotopes that couldnt possibly exist in our process...
- X ray is not a sort of electron it is jumping of electron from the high orbit to the low orbit
- thank you again
- Absolutely! Eu152 is more broadly distributed than Ba133 (another popular isotope) and makes a great tool for detected efficiency estimations.
- *really
- I was unaware that anything was being made in Fukushima. Hasn't most of Fukushima been evacuated? Anyhow, if things are made in Fukushima, it doesn't make them radioactive. They would need to contain fallout and most of the parts for small electronics are very clean to start with. Realistically, this sort of thing would require testing in a lab, but I would say, most likely not. None of my iphones nor my ipad have been radioactive by anything other than potassium.
- i want a plutonium finder, do you have one of these ?
- I found the Gamma Ray producer from lightning... antihydrogen fusion in a self contained sphere thats released above storms to produce a sprite. This is a fusion event is energy helium is spun off to the moon, carbon ring liquid oxygen and as the fusion is slowed to carbon again. New discovery
- Oh... didn't really answer you did it...? I have consider it. I have always been interested in Na22. I currently own the following samples from Spec Tech. (* indicates fully assayed to 95% accuracy) Cs137 - 37kBq *Cs137 - 3.737 kBq *Eu152 - 37.37 kBq Sr90 - 1 kBq *Co60 - 33.781 kBq Po210 - 3.7kBq (about 1 kBq now) Po210 - 3.7kBq (about 600-ish kBq now) Thanks Spec Tech!
- I actually generated lots of positrons by converting Aluminum 27 into Phosphorus 30. =) watch?v=N3eqJgG_-gw
- Oh really I have some Japanese green tea. I better keep not drink it to be sure. I bought it around the height of the disaster.
- Fukushima was evacuated im pretty sure.
- Plutonium is actually hard to detect, directly, just like uranium. Typically, you attempt to detect daughter (progenic) isotopes of plutonium. There are over a 20 isotopes of plutonium (only a few long lived ones) and each has it's own decay chain. Take the famous Pu239 (U238+N -> U239 ->Np239 -> Pu239). The alpha decay of this isotope is U235, which is found in nature, making detection of Pu239 actually quite difficult lol I'll do some videos on specific isotope ID (like, uranium, etc)
- how much to buy one of those ?
- It's not a silly question at all: I screwed up and had the "hide cursor" check box marked when I make the video. lol
- Also, have you considered forking out for a Na-22 source? Spec techniques sells em. Would be great for demonstrating anti matter and annihilation.
- The Gamma Spectacular is something like $300 USD. You'd need a probe too, which can be between $500 and $1000. Gamma spectroscopy is costly no matter what, but now it is cheaper than before. My spec tech UCS30 + 38.1mm NaI(Tl) + Shielding = $5000 +/- It's a really good unit too, but consider the cost. My polimaster 1703Mo-1B = $2700 So... All for under $1000 is a great deal :)
- Nice video, do you have a simple PRA calibration video. Also theremino being easier to calibrate and calibration near test sample energy, can greater linear accuracy be gained across range with equliser feature and multi known sources? thanks
- Hi! The iphone has some parts assembled in Fukushima, is this dangerous due to radioactive? please answer me
- Hi, very silly question: why can't I see your mouse cursor? I have the youtube video resolution at 1080p. You reference the things you're pointing to very often in your video, but I can't see the mouse cursor at all.. Can you help explain? Thanks :)
- Yes! If you have 4 to 5 thousand, get a UCS30, but if you don't, get a Gamma Spectacular. Spend the $ on the detector and get a good one.
- nice clip and info Tom! But I wonder about Cs137 for calibration... one must then know that the probe has a near linear response... Also, the cost of building your own probe is only a fraction of a pro unit, and possibly just as good or better. for example, there are great soviet crystals...
- An x-ray is a photon of quantitized energy whose energy comes from the change in momentum of an electron as it makes a quantitized leap between a wave number to ta lower wave number. In short, an x-ray is the discarded energy from an "orbital" transition. X-rays tend to come from electromagnetically initiated change in momentum, whilst gamma rays tend to come from strong force initiated change in momentum, though both x-ray and gamma are just photons with short wave lengths (high energy).
- No worries. It is a valid question, and I do not know the answer for any specific item, but in general... I would suspect what I said was correct. Be sure to ask others and form a consensus. Trust me on this lol I've been wrong at least 10 times this week, so far lol
- please, answer me
- 100% true! I am making my videos on this subject for the beginner. Personally, I am only now at the point where I would consider making my own probe (and I am planning on a very unique one too lol). The probe I wish to make will require computer control and me brushing up on linear algebra :) As for the calibration, you are also correct (I point this out in the end of the video). Video 2 will be more advanced and cover no-so-linear probes, such as my own probe. Cheers!
- Yes. The question is a valid one, but one which I doubt will come up often for non-foodstuffs. Devices, like iPhones, are made in clean environments to began with. Something like green tea could actually be contaminated, because the tea comes from the ground. In fact, I have tested a dozen or more green teas from Japan and found two of them to contain Cs137. :|
- Great video Tom. I'm into gamma spectroscopy, and would of loved a video like this when I was starting out. Hopefully others will appreciate this too! Gamma spectacular is a great MCA, especially for new users.. I would highly recommend it. That way you spend more on a good detector, and if you want to do low-count samples, lots of lead..
- Very nice selection. Eu-152 is a damn interesting source, gamma rays all over the place.
- Thank you so much for the answer. That's realy useful for me
