@astro_alexandra: A nuclear reactor in space crashed over Canada #space #Astronomy #Science #edutokcontest #learnontiktokcontest

tyrantreaper6 :

Uranium is naturally occurring and not very radioactive. I’d worry more about the fission products.

Ruben_Kelevra :

Canada also fined them 3 million for littering 🥲

Ncryanj :

So they had nuclear reactors small enough for a satellite in the 70s but we can’t get one for out houses

henryrierson :

that's how I got super powers but I traded them for a Charizard in 99, but I sold it later for rent

M. A. Kidd :

There is no such thing as “burn up” in the atmosphere. Everything burned or not returns to earth.

Grillon Fute 🇨🇦 :

Has technology not advanced enough to detect radiation by drone and find all the rest?

GeckoToe :

704 million years is insane!

Mr. Kakoona :

Hearing as 2 hundred and 35 sounds odd. It’s usually uranium 2 35

Firestone :

what part of Canada?

5.11.75 :

My uncle worked for the DoE at the Nevada Test Site at this time, doing radiological photography of the caverns left after underground shots. He was part of the team searching for this debris

Tomushki (Yakub edition™) :

I've heard so many different half life's for u235 idek which one is real 😔

Colin :

U-235 is not easy to find. It’s primarily an alpha emitter, that releases high energy X-rays sometimes. So most of the detectors that work in a long range don’t work. You need a very sensitive Xray probe and then you start picking up solar and cosmic radiation in background which mess with your readings. If it was still encased in berillium you might get neutron readings which are MUCH easier to detect…unless it ends up under water

Itchy_Kockov :

canadian here.... Dafuq!!! 😳😳😁😁😁

kenun :

no

Daniel_17_17_17 :

704 million years not great not terrible

𝜙 PHASE BRO :

reckless

bozzbongz :

what do u mean it's still out there?

James Greenler825 :

Aliens must be very disappointed in us .

Colin 🐉 :

I saw that years ago

Arlo de parlo :

Don't they have satellites now that can pick up that radioactivity?

Marker 89 :

when this happened?

Bob Oso :

nuclear fusion is the only way we will be able to travel to far away places

polkins :

But don’t most satellites have reactors or radioactive isotopes to provide power? I’m guessing due to weight, reactors would have a pretty specific use case but they e all got radioactive fuel cells don’t they?

user178622139692 :

Almost everything in space is powered by radioactive materials. The only difference is this one was an active reaction rather than decay.
