Wow interesting video
All correct, except note that the GM tube method of detection is inappropriate and misleading here. Even with a thin mica pancake detector that can see alpha radiation like the kind you're using here, the detection efficiency for low energy few KeV x-rays is spectacularly poor. In fact you need a special kind of scintillation detector to efficiently detect low energy x-rays / gammas like this and if you put one up against the side of one of these light sources it would indeed be screaming.
put one up against the side, you mean like a keychain light in a pocket right up against the skin?
Neat video I was curious about the safety of these.
It is interesting that they emit low dose gamma radiation
@@BrianDhvTinkerer Is it still dangerous
@@osamabinladen824 I doubt it. The levels are likely to be quite low
You absorb more background radiation just standing outside for an hour than you’d absorb from wearing a trit fob for a whole year.
Tritium is also one of the most expensive substances on earth, costing a whopping 30,000 usd per gram. The vial that you have, I believe is 1 milligram. So 1000th of a gram, which equates to 30 usd for that vial. So damn even 1 mg is crazy expensive for that little thing.
Yeah see what you mean that’s a lot
@@BrianDhvTinkerer yeah
@@BrianDhvTinkerer I bought a 5 inch vial that costed over 100 usd
@@legendarypillow1450 where you find a 5 inch vial?
@@savage101. on some websites
4 times background is pretty much nothing.
Airplanes on maximum height(10km) have around 100x background
Noice. So I get to use one of those :D
people carry these in their pocket 24/7 and its pretty much direct contact dose. i would not do it.
@@TMS5100 Aaaaaaand you are wrong. The radioactive effect that this has is a fart in a wind storm compared to things we interact with daily, hell your phone or computer will do more harm than this thing. Do an ounce of research before commenting.
No worries because they're not beta particles, just X-rays and Gamma rays. 👍
In fact they ARE beta particles which interact with the plastic casing and due to bremsstrahlung interaction they become X-Rays.
How if gamma penetrates farther than beta?
No way that's going in my pocket next to my balls :-D
I wonder. What if you put 100 in a flashlight shell.
serious question
can tritium be crushed to powder like ceramic?
if it does will it still glow?
No, it cannot. Tritium is just Hydrogen chemically. So you'd have to react it with something like you would do with hydrogen to make a solid. It would then probably glow even harder.
Like Male Sylveon said, no.
Tritium is a gas, the glowing is the phosphorescent coating in the container that is actually giving off light. You COULD make phosphorescent beads or micro particles to submerge in the tritium though.
It comes down to how luminescent the phosphorescent material is, how small they are (for beta penetration), and how rarefied you could make the combo. Since beta radiation has very little penetration, small, easily excited phosphors would be your best bet IFF you were looking for a solid. Still, hard to beat phosphors on the inner wall of a glass vessel.
@@akureiokamii I love when people give helpful and accurate answers. Well done good pokemon. Well done indeed.
Hydrogen-3 (Tritium) doesn't emit gamma ray energies or characteristic X-ray energies when it decays to Helium-3. Only very soft beta particles with an endpoint energy of 18.6 keV @ 100% intensity. Bremsstrahlung (secondary/braking X-radiation) is the only thing that is detectable from H-3 decay. Also, the only thing that differentiates X-rays from gamma rays are their origin: X-rays are emitted from the orbital electrons-gamma rays are emitted from the nucleus.
Also, the beta radiation can only penetrate about 1/4 inch of air, and cannot penetrate the dry epidermis of human skin. There is no health risk from this type of light source.
> Also, the only thing that differentiates X-rays from gamma rays are their origin: X-rays are emitted from the orbital electrons-gamma rays are emitted from the nucleus.
Not exactly true. Would be nice if it were so easily categorizable:
> There is no consensus for a definition distinguishing between X-rays and gamma rays. One common practice is to distinguish between the two types of radiation based on their source: X-rays are emitted by electrons, while gamma rays are emitted by the atomic nucleus.[58][59][60][61] This definition has several problems: other processes also can generate these high-energy photons, or sometimes the method of generation is not known.
The problem is people carry these in their pocket, which is very nearly direct skin contact. Instead of a few inches away, you should have put the detector directly touching the vial, as it would be if carried in pocket on a keychain.
I've done this with my pancake detector and let's just say, I do not care to carry tritium keychain lights in my pocket.
You'd get more radiation by flying a couple times a year than having one of these in your pocket.
It emits beta not gamma rays. Believe they can’t even penetrate the skin.
@@Meatislife gamma bremmstrahlung with 18kev are created when the betas slam into the glass enclosure. see th-cam.com/video/4Y3Hu6hEwow/w-d-xo.html for proof. do you want to carry that around in your pocket all day? i wouldn't do it.
... and does it or could it produce heat if it were broken open or modified?
They produce small amounts of heat from the radioactive decay. If tritium gas was compressed, there woukd be significantly more heat.
SciTubeHD aha. that is interesting. But still, would a mountain climber know all that, and have one, 50+yrs. ago? Thank you. I shared this on Paul's channel.
@@alanmalcheski8882 You would not feel the heat. The increase in heat would be only some tiny amount not relevant to real world use.
@@akureiokamii Thank you. I was asking because I had a theory about the Dyatlov Pass incident, in Russia. Some hikers got caught in a blizzard, then for some reason, some of them abandoned their camp, in freezing weather, unprepared, and died, and then the others died. A recent update on that case revealed that forensic analysts found radiation, on them, I'm not sure which ones. I was thinking maybe they had one of those lights. But another update said that there was some kind of weapons testing going on, they think, and that's where the radiation came from.
I have one of these from Glow Rhino and it hangs from my rear view.
From where you get ?
Ebay
Thank you for your video. I wear a titanium jewellery item with 6 Trigalight Tritium vials, around my neck, which are not covered by glass. My Mira dosimeter doesn't seem to be picking up much radiation. I am really curious about two things:
1. Am I about to die horribly from chest cancer because I wear a necklace full of tritium vials.
2. Am I about to turn into a super hero because I am mutated by wearing tritium vials.
Let me down gently.
The level of detectable gamma rays is very very low. Would take several lifetimes to see any effect if at all!!!
Yea you are probably fine. But they aren't meant to be jewelry so I wouldn't suggest wearing it on your skin daily
Essentially it is only dangerous if you break the vial and inhale the tritium gas. Then yea beta particles will slam into your tissues. But contained in minor glass or vial or plastic or clothing would stop that radiation.
Exact same question I had haha. I want to buy some cool Tritium jewelry!
@@pharaohsmagician8329 I got a RovyVon Ti Walker EDC Titanium Bead. Its best to shop around Pharaohs. I got mine cheap with a stainless steel chain, and bought the 6 tritium vials from EDC Gear in the UK. The green ones were very bright and overall it was cheaper than buying them as a package. I would note, go for a stainless steel good quality chain. I burned through multiple sterling silver chains because the clasps are shite.
Sir what is the brand name of this key chain plz I want to buy
a.aliexpress.com/_dYo7szh there you go mate, take the green one this is the most bright one
Glow rhino
What will happen if the keychain glass breaks ?? Then will it affect us ?
Even than its pretty safe, unless your in a confined space with no ventilation for an extended period of time.
You’ll grow an extra limb lol
@@JoshuaDomoslai lol
It will just leak. It will leak into the atmosphere and just be gone after a few minutes. If you inhale it it won't make a big difference it won't interact much at all with you. You'd exhale it in the next breath. It is 100 % safe if you do not snort it.
I've had one that's been glowing for over 20 years
Nice
YEah, the half-life is 11 years, so after 20 years it should still glow about 1/4 as bright as when you got it originally.
Is it produce light automatically or stores light and emit it like radium...????
@@lifeisbeautiful6329 some sort of low level radiation light I think
@@lifeisbeautiful6329 the light is produced by the decay of the tritium. The tritium decays in to an isotope helium 3, after emitting a beta particle. The tritium doing this excites phosphors that are covering the glasses surface on the inside. This creates light. So it will glow with out being charged until all the tritium decays which is 50% over 12.5 years
Where did you bought this ?
Got from eBay - www.ebay.com/itm/164228438417
SciTubeHD thanks 😊
@@BrianDhvTinkerer Wait... So eBay is selling radioactive substances? 😳
I understand these emit a lot of X-ray radiation. Is that bad?
They emit a little bit. I don’t think it’s enough to be hazardous.
Actually the dacay of the tritium nucleus emits beta radiation (an electron from a neutron that becomes a proton) with low energy (Max 18keV), and probably low energy gamma ray when it decays in stable helium3 (but I should check on that) . NO X rays are produced. Xrays are only emitted from exited orbital electrons.
Could be right. What I am detecting is likely some braking radiation from the beta particles hitting the sides of the glass envelope containing the tritium
@@kanyewest2476 Thanks Kayne, didn't know you were into stuff like this
If you get a lot of that I think it's bot safe

I swear this guy sounds IDENTICAL to Elon Musk, all the way down to the expressions he uses and his peculiar pronunciations. Crazy
😂
Plz answer ma question..
Is radium brighter or tritium?
10M Views the half life of radium which is much longer then tritium which means tritium emits more beta particles per second then radium since it decays faster. Assuming the fluorescent powder is the same, the tritium will give out brighter light.
Thanks a Ton : )
That clicking is giving me fallout vibes

I'm not going to lie I bought one of these about 8 years ago and I carried it in my pocket and everytime I carried it in my pocket , I started noticing that it would kind of burn my thighs and everywhere where my pockets were hair was missing, it stopped happening after I threw it away
This guy seriously sounds like a nuclear scientist
Indeed
not really lol
Almost the level of a banana XD
No kidding!
I have one
They are very useful. The first one I ever got for in the 1970s
What would the radiation be like if it was broken
It would be a lot but would quickly disperse in the air
lol beta particles
Can I have the Tritium Keychain please ?
Yes . For $ 50.00
@@ronniep777 It's cheaper than that. I got three with three different colours for 55 USD including shipping. Cannot remember where I got them from though.
