Brian, I have 4 observations: 1. Very nice video, as always. Congratulations! 2. I found it very interesting how your new RadiaScan beeps S.O.S. in morse code, until it reaches about 700 uSv/h, when it goes "oh my god get me the hell out of here" constant beep mode. 3. I didn't understand why the uraninite was colder than the table (that was, presumably, at ambient temperature). 4. I also didn't understand why your Soeks and GammaScout devices zeroed the readings in 2015 and did detect radioactivity at this time... Thanks and best wishes!!

[@snowthemegaabsol6819]

To go into a bit more detail about tritium turning into helium-3, this is done through a process called Beta Decay, because when it happens, a beta particle is emitted from a nucleus [a high energy electron/positron] In the case of tritium, a neutron was turning into a proton spontaneously. This happened because the quarks that make up the neutron are capable of changing into other kinds of quarks by exchanging a type of particle known as an Intermediate Vector Boson. In this case, it is a W- Boson, which can be thought of as a kind of messanger particle. To avoid a whole lecture about quantum electrodynamics and field theory, the gist is that while this decay process is happening, a beta particle and antineutrino are being created in a pair. Every time this process happens, they always come in pairs. Neutrons have a higher rest mass than protons. Essentially, it is that extra energy that goes into the beta particle and the antineutrino. There are also some photons involved but those aren't that important. This can also happen with protons becoming neutrons. It's called inverse beta decay, and it happens whenever you have a high energy particle, usually a beta particle or high energy neutrino smash into a proton. The kinetic energy of the collision supplies the activation energy needed to kickstart the decay process. An up quark in the proton by way of a W+ Boson changes into a down quark, and the nuclear potential energy between those quarks rises, giving the resulting neutron the extra rest mass. Some photons, neutrinos, and a positron is also given off as the total energy of the neutron rejects the excess energy from the original collision. After all, quantum particles really love being in their ground states.

[@snowthemegaabsol6819]

oof the quantum jokes. Now to figure out where they're going

[@Cavistus729]

the atomic diagram was really cool and informative! very easy to understand.

[@lajoswinkler]

I would advise protecting your counters with a sealable bag. You don't want the meters to get contaminated with radioactive ores.

[@inverse2k1]

And touching the actual pitchblende sample with the detector's window is a VERY bad idea. Once the insides get contaminated you can just throw the detector away, good luck cleaning it.

[@garbleduser]

When you change the battery, make sure you have the device "on life support" with another power source to hold any volatile memory. Manufactures do this so that if you replace the cell, the unit will stop working. Also, Is there a Dallas chip on the board? Those have batteries to back their circuits potted into the bottom of them. Don't let the power fall out completely!

[@strahlenmesstechnik1567]

You have a nice channel with nice videos! Really nice!

[@kc9scott]

For strong samples, in my opinion it’s a good idea to have a saturation indicator on the Geiger counter. I’ve had several PET scans done (injected each time with ~12 mCi of F-18 FDG), and for several hours afterward, I can drive my Inspector+ (which has a 2-inch pancake tube) into saturation, by holding it near my body.

[@TiSapph]

Interestingly there is more to the x-rays coming from the tritium light sources. While a large part is due to Bremsstrahlung at 5-15keV, there are also pretty strong peaks corresponding to the characteristic x-ray spectrum of zinc, especially the K_alpha and K_beta emissions. However there is still practically nothing coming from these. As counters are calibrated to 662keV Cs137 emissions, they overestimate the dose by a factor of around 70. And of course it's not actually a full body dose. I once calculated the yearly dose for a key-chain with ~200Bq, ~10keV per gamma, 1/2 absorbed (people don't usually swallow their keys :P), 1/2 of the time wearing they key on you. I get around 2.5 micSv for a year, so around 1000-2000 times less than background and around as much as I got from my 2 day trip to Chernobyl, or around 2h of flying... Considering less than 1/2 is actually absorbed since people aren't infinite planes and people don't have their keys on them half of all time, it's probably a factor 5 or so lower still. All in all, the probability of impressing a potential girlfriend with one of these far far outweighs the risk of it! :D

[@sbreheny]

Where did you get 200 Bq? I think the tritium light sources are more like 10^9 Bq. However, once you work out how much of the super low-energy x-rays are produced and actually make it out of the glass vial, it becomes only a few counts per second.

[@sbreheny]

For example, I have a Betatorch which is a British military tritium illumminator which is about the same surface brightness as a keychain tritium light but the surface area is much larger (it is designed to provide just enough light that you could read a map in total darkness but not be seen more than about 20 meters away). It has 1.9 Curies of tritium (7x10^10 Bq)

[@TiSapph]

@@sbreheny I held of in front of a scintillating counter and got ~100Bq, bit below. So ~200 or in that range total. It was a Nite GlowRing if I remember correctly. Honestly somewhat unscientific since the scintillators aren't really meant for these low energies. I wouldn't think it's far off the actual value but there is no way to know for sure other than using an x-ray detector. But in the end even if it's a factor of 100 greater, it's still less than a tenth of background and personally wouldn't bother me. Edit: oh you are saying you would expect less. Well could be, I really just grabbed the next best scint counter while doing student labs. Beforehand that I expected less as well, especially because IAEA has a paper that speaks of 28mic penetration depth of the x-rays through glass.

[@Spirit532]

@@TiSapph So you're saying you did extensive math based on... waving a random-shape and random-area source in front of a random-shape and random-volume scintillation detector that only shows its own estimated total absorbed dose? Yeah... nice.

[@TiSapph]

@@Spirit532 Um not quite? It's a scintillation counter, not spectrometer. It only counts the number of pulses, not their amplitudes. And then I did a fairly simple one line order of magnitude calculation to get a sense of how much dose one of these gives you. Also I think it's seems pretty fair so assume that if you have a small object on a decently large detector, the total activity is going to be around 2-3 times that much. Even if it's actually like a factor of 5, whatever it's an order of magnitude calculation. Don't quite get what the issue is

I like the range (0.01 uSv/h to 10 mSv/h) on it, but I have no idea how you would test the 10 mSv/h range without doing something stupid like breaking into an old mine. With that range I'm wondering if the 700 uSv/h reading would be instant and accurate. Edit: I did just realize the RadiaScan has a 10 mSv/h range. That's undoubtedly why it is quicker and more confident than the others with the higher doses.
