I see the stylisric reason to only apply the effect around the object, but it isn't realistic.
That radiation isn't affected by optics, it'll go right through the lenses that flip and focus the image and the aperture that might be engaged, and will hit the entire sensor equally. The entire image should be that noisy.
Even if it got blocked, there's a fair bit of metal in a phone which will produce Bremsstrahlung under beta radiation. Obviously that's only going to hit your face, not the sensor.
So if you had a camera with mirror would it still go a bit through the enclosure and hit the sensor?
What if the sensor is flipped so it has to go through the silicon substrate before hitting the sensitive bits, would it be equally noisy but less noisy overall?
Yes. Silicon substrate is too thin to matter. Redirecting with mirrors is probably gonna make it worse. Your housing would need over a cm of solid plastic to block beta radiation. On a dedicated camera you might have a sizeable lens with many lenses totalling a cm of shielding, but redirect the light and place the sensor not behind the lens and you only have that camera housing.
Realistically though you have a smartphone, and that β-radiation will probably make it most of the way through the entire thing.
And the gamma radiation really won't care, even if you have a 50cm long zoom lens right between the sensor and source.
This is where you might want a lead brick wall, 10cm thick should make it short-term safe for ⁶⁰Co.
I was going to include a tangent on how difficult it is to shield a spacecraft from cosmic radiation, but I'll wait for a more appropriate post. Thanks for the refresher.
Never abuse warning labels for comedic effect. This is deadly.
A few years ago, there was a news story about a guy driving with radiation warning labels on his car for fun. He got fined HARD because he wasn't certified for that or had the permits .
Doesn't matter if you don't have actual radioactive material. That shit is illegal for a good reason.
I highly recommend holding it within 3 feet of your body for 5 to 10 minutes; absolutely nothing can go wrong from holding a Cobalt-60 source with 3540 Curies in 1963 within 3 feet of your body for 5 to 10 minutes!

Yea my thoughts too,... although with less facts to back them up
Beta particles wouldn't go through the glass in the first place.
The beta emission of ⁶⁰Co can probably get through over 6mm of glass. This should be plenty for phones.
But also

You sound like fun
If you don't like neurodiverse people going off about special interests wtf are you doing on 196?
Perhaps he means it
thanks! :)
I'm having fun, so thanks
And leave your bad vibes at the door, tank you
Good reply
Oh cool

Edit: forgot this was in general, not about the β

Replicas of Cobalt-60 sources can be got on Ebay for as little as $12.
With or without the camera degradation? I'll bet that cost extra.
why would you even make that what purpose does that serve
Telling a physics grad student to catch it and then seeing their existential dread?
You are evil! I like it :D
Paperweight / conversation starter. As long as you know it's not real, it's just a cool chunk of brass.
Shouldn't be allowed to exist. This removes the terror and fear of seeing an actual Co-60 rod and may kill someone.

Yeah, wasn't a source lost on the side of the road in Australia a year or two ago where anyone could have picked it up if they didn't know better
Yes, 3 years ago.
These things are no joke. Proper labeling is no joke. They found it at some point. Just went where they had been and used a Geiger counter.
Yep. The only reason it should exist is for a demonstration piece, to say if you see it to drop it and run, and inform the proper authorities.
In this case it should also have engraved something like " not actually cobalt just a security training mock"

Y’all looking at the radio-active isotope, while I can’t see past the mutated hotdog fingers
Replaced phone after the screen started bubbling for some reason.
Hand fell off.
Using other hand on a new phone, but I'm having trouble seeing anything at all now
thnx
Yeah, that’s not very typical, I’d like to make that point.
That's a magic wand which makes the air taste like pennies.
... forbidden toosie roll ...
It's so rads!
This should be a 3d print
Omg yes

I want to eat it
Forbidden Tootsie roll
go for it
YAY!!
My neighbour really wants some strontium 90 flavoured chocolate.
Looks like a radiation warning on that.
