the Google maps thing jumping from city to city was fun to watch.

[@Adiki3]

One chest CT scan and we get half of a year flying 24/7 :)

[@terrypitt-brooke8367]

great, as always! What about Day/Night. Surely having the earth as a shield from the solar contribution would make night flights less radio-hazardous....

[@robclements4957]

I was JUST talking about this. Thanks.

[@sashboo1370]

You had mentioned this video was coming out soon and it was fun, it did not disapoint. Thank you for the great content!

[@kwokhardy2512]

I noticed that Germans prefer the letter K over C

[@user-pr6ed3ri2k]

let's start exhaling KO₂

[@skyethebi]

@@user-pr6ed3ri2k that would be interesting considering potassium superoxide can actually convert CO2 into O2

[@meloney]

​@@skyethebiso we should inhale it instead?

[@skyethebi]

@@meloney it also reacts with water to form potassium hydroxide, hydrogen peroxide, and oxygen

[@brfisher1123]

Again, anyone who has a collection of fossilized shark teeth especially those of the megalodon should test them out for radioactivity as I have a 5.6 million year old megalodon tooth that is fairly radioactive which was kind of unexpected to me when I first discovered it!!! ☢️ 🦈

[@brfisher1123]

Do you collect fossils? I don’t know if I’ve already told you this before but I have a 5.6 million year old fossil megalodon tooth that is quite radioactive due to uranium that has been incorporated into the tooth during fossilization! ☢️

Minor nitpick. While most commercial airliners fly somewhere between 30,000 and 39,000 feet, private jets are optimized for higher altitudes. The thinner air provides less resistance and they can be more fuel efficient at those altitudes. Also, since there is less turbulence, it is generally a smoother ride. I don't know what flight levels Taylor Swift's jet normally flies at, but you should assume that it is higher than airliners. Her Dassault 7x can fly as high as flight level 510 or 51,000 feet. That's a little over 15km. Even if her jet doesn't always cruise at maximum altitude, it's probably still going to be somewhere around 45,000 which comes out to over 13km

[@SimonsNuclearchemistry]

I learned somthing New :D

[@LFTRnow]

I also looked this up as I thought private jets flew lower than commercial. The opposite is true as you said.

[@CaaPoraSpirit]

Dude came here just to understand what the heck did she have to do with rad and this was genius

[@Havron]

Simon, you say that the neutron radiation experienced in flight is too high in energy to lead to nuclear transmutation, but then later explain that collisions with these neutrons are precisely how atmospheric nitrogen-14 is transmuted into carbon-14. Won't the same sort of reactions occur directly in your body as well to at least some degree? Of course the rate will be very low and so very unlikely to be of concern, but it must happen on occasion, yes? Does the extremely large and ever-present upper atmosphere simply afford these neutrons many more chances for a successful reaction?

[@SimonsNuclearchemistry]

exactly what you are saying :D its just a numbers game. The cross-section for this reaction is around 1 barn. Which is ok if you have a high neutron flux OR pretty much infinite time and a whole atmosphere as target.

[@MagicGumable]

well, you got a radiacode right? It would be interesting if you could go on a couple flights and maybe even measure window vs aisle seat and first row vs last row seat. Ofc all for science

[@SimonsNuclearchemistry]

Would be nice. But "flying" for a Video isn't really a casuall Option for a Student with 3000 subscribers😅😂 remind me when I have my next Variation next year ... maybe 🫠

[@rkim9560]

Ive actually tested this with a Radiacode 102 from Detroit to Amsterdam, and I‘m not confident it’s well suited to the task, as the average dose rate for my flight was about 1uSv/hr with a maximum of a little over 1.2uSv/hr. As always, further research required

[@MagicGumable]

@@SimonsNuclearchemistry i will remind you when you have 1 mil subs... that one irish flight service has those cheapo 20 Euro flights ;)

[@fregtz735]

​@@SimonsNuclearchemistry maybe use a weather Ballon or other unmanned vehicle?

[@LFTRnow]

There's actually quite a number of videos out there with radiation detectors on flights. I've yet to see a proper spectrometer of them, and that would be interesting.

[@James-xu3vc]

Can you do one for RUSH 🇨🇦 ?? 😂
