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

XNtricity :

Hey, random question: how were you nominated for that "Creator of the Year' thing, but still not verified?

Mr. Kakoona :

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

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

GeckoToe :

704 million years is insane!

Toma (Yakub edition™) :

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

Grillon Fute 🇨🇦 :

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

Firestone :

what part of Canada?

Colin 🐉 :

I saw that years ago

Marker 89 :

when this happened?

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

downtroddin :

Who is “they”?

user178622139692 :

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

𝜙 PHASE BRO :

reckless

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?

kenun :

no

tyrantreaper6 :

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

Rogal Dom 🇨🇦 :

Ain't no reactor like a Soviet-built reactor

Arlo de parlo :

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

Daniel_17_17_17 :

704 million years not great not terrible

Krobravodor :

50kg wtf WHY SO MUCH POWER

White Dragon :

it's not most satellites work on nuclear rods? like voyager

Space Dandy :

It wasn't a "whole" big nuclear reactor, it was most likely an RTG that contain a lot less radioactive material than a reactor
