Thanks for another great video. This reminds of some work I did many years ago. We were considering the use of mercuric iodide (HgI2) crystals as room-temperature x-ray detectors, and we wanted to look at its sensitivity to radiation damage. The crystals would be irradiated with electrons, then their properties would be measured. When checking the collection of electrons, I could use our standard x-ray sources. However, the hole mobility in HgI2 was much lower, so I had to use alphas from Am241 as a source, so that sufficient charge would be generated. BTW, the alphas didn't penetrate your detector for the same reason that they generate ionization in the air. Their stopping distance is very low because they plow into the material and produce so much charge.

The video is quite good and I enjoyed it. One question that I had concerned the method of producing the polonium in place by bombarding a gold plated film of bismuth. The neutrons would also activate the gold film and create a source of beta rays when the Au-198 decays to mercury. Are there any beta emissions from your static master source? Edit: I searched and found that it also has gamma emissions. Another Edit: I had a long talk with a guy from NRD, who make polonium anti-static devices. It was really interesting. Long story short, bismuth is irradiated in a reactor, the polonium is separated by vacuum distillation. The polonium is alloyed with a mixture of silver/bismuth. The polonium forms a eutectic mixture with the silver. The alloy is passivated with layers of gold and nickel. Cheers.

@@cassandra2860 I agree about the Au-198. One thing I remember from reading about polonium engineering during the wartime is that the stuff was amazingly mobile. Early shipments of the stuff for the Urchin initiator would arrive at Los Alamos and be alarmingly spread out. From Richard Rhodes book; 'Thomas shipped the Po on platinum foil in sealed containers, but another nasty characteristic of polonium caused shipping troubles; for reasons never satisfactorily explained by experiment, the metal migrates from place to place and can quickly contaminate large areas. 'This isotope has been observed to migrate upstream against a current of air,' notes a postwar British report on polonium, 'and to translocate under conditions where it would appear to be doing so of its own accord.' Chemists at Los Alamos learned to look for it embedded in the walls of the shipping containers when Thomas's shipments came up short.' Cheers.

Very nice! This is a great video! I have about 500 μCi of Americium-241, but no fresh polonium-210 sources currently. Am-241 emits a decent amount of low energy gamma rays with a branching intensity of about 36% for 59.5 keV gamma rays and 5.4% for 26 keV gamma rays. The rest of the over a hundred gamma ray energies are less than about 1% and more, so they hardly contribute to more gamma radiation. Po-210 does have a fairly high gamma ray energy, however it's branching intensity is so low, only about 0.001%, so it's often negated. Po-210 only has a half-life of 138 days, so it has to be used fairly quick. Too bad they can't just use Pu-239. It's a nearly pure alpha emitter, and your brush wouldn't need replacements.

The accelerators are pretty good but not very powerful or versatile as they are. But with enough dedication it should be possible to upgrade one up to the required level. Pretty much the only thing you need to do is to cut off the scteen, to modify the electron gun to allow for local discharge and slow gas introduction, to replace the magnetics, to build a semi-sealed chamber with enogh space for accelerstion pathways and target, to add a vacuum outlet and to design new beam control circuits. It is not a single weekend project but I belive that you can have a personal particle accelerator if you really want it bad enough for whatever reason.

no shit and also if you mean with "man" made by like putting togheter with adding neutrons, elektrons and protons than your wrong. They just shot at an element with like a highly energetic neutron or something to make it unstable and start to decay and turn into polonium or something.

Now you just need a bit of beryllium and you can initiate your gadget.

Wow. Awesome demonstration!

Cool way of lighting the candle!

The company behind these strips(and StaticMaster brushes) will happily sell you a 500 MILLIcurie source after you sign a waiver. It's nuts.

Heck, you can buy tritium-powered radioluminescent flashlights (used by the military to read maps and such at night) online for around 100 bucks, some of them contain a 1.9 Ci tritium source in a fused quartz ampule.

A few other comments here also mentioned using it for photography to remove dust from negatives. And compared to many other things integrated in our stuff today, probably not that bad really. Produce enough of it at a decent scale and many things can work out to economically make sense.

Interesting, Could you show the "Staticmaster brush" working?

A very Aperture Labs approach to the problem but a conceivably viable one if equipment is less expensive than employees.

You should get another cheap geiger counter without a metal shield around the tube so you can detect alpha. My orange fiesta-ware dishes with uranium-oxide glaze are great alpha emitters! Now I want to get a HV power supply and make an arc detector like this!

You can also get soviet SBT-11A (СБТ-11А) geiger-muller tubes for less than $30 on eBay. They are great at detecting alpha, and can be hooked to any geiger counter (if the voltage is right)

Holy crap, that was great! Thanks Ben!

Hi! Thanks for this awesome video! Side comment as to why the Geiger counter detects your strontium sample - Beta decay is almost always accompanied by (secondary) gamma radiation, as it is a way for the daughter atom to release extra energy from the transformation. Alpha decay can also be accompanied by gamma radiation.

Wow, just wow! Thanks for this video!
