Touched a Nuclear Jet Engine Core with a New Radiation Detector

I test out the new Radiacode 103G against the reactor vessel of some nuclear jet engines using a pole to get over the fence. The new 103G uses a different scintillation crystal that is now being used by DOD and NASA for radiation sensors.

Just a small correction here, mercury _is_ more dense than lead, lead has a density of 11.34 g/cm³, while mercury has a density of 13.55 g/cm³.

I picked up a container of mercury in HS Chemistry class (Prof was a nut!), and its deceptively heavy! It was not a large container either.

Dang…totally thought it was the other way around. Thanks for the correction, also now it makes even more sense why they used it to kick down the radiation.

[@TheExplosiveGuy]

@@repro7780 Yeah it always surprises me when I pick up my flask of mercury, it's only 1.5 inches in diameter and only has about 3 inches of mercury in it yet the whole thing weighs a little over four pounds (the steel flask weighs about 1/2 pound by itself). Mercury _really_ shows off its density when shaken or swirled too, it's such an odd sensation since the weight is so easily shifted around, mercury is only slightly more viscous than water so it flows extremely freely. It's probably one of my favorite elements...

[@TheExplosiveGuy]

@@RadioactiveDrew You're welcome, and don't sweat it, a lot of people think lead is one of the heaviest elements (it's definitely not lol, it's literally half the density of Iridium and Osmium, which are the two densest metals on Earth).

[@pchris6662]

The probe detached from the handle with a shielded cable.

You might ask your connections at radicode to maybe start an upgrade program for the 102 or 103 to the 103G for maybe a price of 3 or 4 hundred dollars. I can not buy a 1 cm2 Scintillation GAGG crystal for 4 hundred dollars. They must have cut a deal with a manufacturer. I should add that the GAGG crystals used for this application are dopped and not cheap ones you can find on Ebay used for making jewelry. There are actually several doping processes used to make crystals for higher light outputs or faster recovery times. I think that by using GAGG crystals that they are probably reaching the limits of their processing or processor speed.

[@juslitor]

Given the small size of the crystal, most likely it is the limiting factor. The annihilation peak above 500kEV also suggests this.

[@hughezzell10000]

I remember when you could walk right up to those jet engines years ago. We didn't screw with them because we were intelligent and stayed away from radioactive things. The actual cores for those two engines, I believe, are buried on the Idaho Lab site somewhere. I dont remember the locomotive being there then. The trash from the EBR accident is buried right there on the EBR site. I saw the first video you posted on the Cesium contamination in Montana. I'd suggest you replicate that experiment near Rachel, Nevada in association with the Sedan event. I believe the fallout from Sedan fell over Rachel, to the north. There are mountains all around Rachel with crevasses that probably hold Cesium and, possibly, other isotopes for you to see. They'll be in greater abundances since they're very close to the test site. Might be a fun trip. Look up Sedan and see the fallout pattern.

I then brought that spectrum to a nuclear physicist and he told me it was most likely an escape peak and not actually Cesium 137 because, there was never any fission at Rocky Flats. I then bought a much higher end Gamma spectrometer (USB) and dug up some soil from that area and put it in my lead pig and tested it. It really showed that there wasn't any cesium in the sample. I'm not saying that there wasn't Cesium at your site, I am saying that more investigation may be necessary.

[@Ganiscol]

Or the Tory II nuclear ramjet engines of project Pluto. Blowing the fallout out the rear was probably sort of a desired side effect of the concept, as it would irradiate the land along the flight path to the various bomb release points. In addition to liquify organs of unfortunate victims below while zooming by at 500ft going Mach 3. Possibly the most sinister concept for a WMD delivery system ever conceived. None of those test engines exist anymore, though.

Drew, your videos are awesome! I think I might buy a radicode at some point just to go rad hunting. Looking at some fallout maps, there might be some in popular hiking areas around me.

[@RadioactiveDrew]

Its a fun device to have with you out and about. I take mine out with me every time I leave the house. I'll usually run the radiation map tracking function on walks or bike rides. I also run it when I'm on roadtrips. Its fascinating to see the radiation levels over a large area.

I'm waiting on my delivery of a Radiocode 103 on Thursday! I live in Cumbria in the United Kingdom and I like walking in the hills. After the Chernobyl disaster farmers here were not allowed to sell milk from cattle etc. What should I be looking out for when I take the Radiocode up into the hills?

Lots of granites and similar rocks can have potassium in their feldspar. So potassium-40 doesn’t seem too surprising. It seems that almost all the argon in Earth’s atmosphere is argon-40, which means that it’s from decay of potassium-40 that didn’t decay to calcium instead.

[@yyzttr]

Granites have Feldspar which are aluminosilicate minerals containing varying amounts of potassium, sodium and calcium.

Filming a crime. Classic. Also 8:10 nice product placement.

[@RadioactiveDrew]

As far as I know...no crime was committed. Thanks, glad you liked it.

@@RadioactiveDrew thought the no trespassing was on that area mainly a joke comment though.

[@kennethnielsen3864]

Thanks for sharing.

[@RadioactiveDrew]

Thanks for watching.

Do the Radiacode units have a automatic isotope identification function? I understand that you can go to a peak and it will id it, but since many isotopes need a minimum of 2 or 3 peaks for a reliable match, an automatic mode would seem useful.

Lead does float on mercury. It also dissolves... Messing your mercury up.

[@RadioactiveDrew]

Yeah, I had the densities switched around.

I wonder where the prototype and full size nuclear scramjet engines for Project Pluto are these days?

[@tdolan500]

9:53 imagine he knocked it off the pole at that moment 😅

[@RadioactiveDrew]

That gaffers tape is pretty good...but yeah that could have happened. Then you would have seen a video of me parking really close to that fence and using the same pole standing on top of my truck to try and get back the 103G.

[@OnTheRiver66]

Feldspar can contain potassium and I suspect that it what is in those rocks. You should pick it up as well in cements and concretes with something that sensitive.

[@bruehlt]

How long will the detectors in the Radicode devices last?

[@ArsenyKuznetsov-eu2tu]

Scintillators are much more radiation resistant than geiger counters, in normal use they are virtually immortal.

[@juslitor]

@@ArsenyKuznetsov-eu2tu They do degrade over time from radiation induced crystal flaws, but it is directly related to how an intense field they are exposed to. More gamma, more bad.

[@Properly-Gapped]

What’s the 103G got over the 103? Is it a better model?

[@RadioactiveDrew]

Has a different scintillation crystal. I talk about it in the video.

[@Tylerx-z]

When’s the store being restocked?

[@RadioactiveDrew]

Hopefully soon. I have a bunch of stuff to catalog and list. Might be able to get stuff back in next week.

[@stephenallen4374]

Next time you go to one of these places ring up beforehand and try a personal tour

[@christophertiredofbs8514]

I totally saw a UFO at 1:03 🛸👽

[@nealelliott1360]

That's a good place for kite airial photography with a Geiger counter attached.

[@LtKernelPanic]

I'm most likely going to be treating myself to a 103 as a birthday present soon. The 103G looks amazing but for my use I think the normal 103 will be fine. One thing I am curious is if their iOS app still sucks. I'd rather not have to buy a cheap android phone for one app.

[@vbzfei]

Danke!

[@RadioactiveDrew]

Awesome…thanks so much.

[@christopherleubner6633]

Looks like Dre has gone on a fission trip.😅

[@CreamyPennePasta]

Where did you get your shirt from?

[@RadioactiveDrew]

I sell them at uraniumstore.com
