The Neutrinos? From Dimension X? They're so cool they're frozen!
Funkt4st1c@lemmy.world 2 months ago
Tbf you actually want 0 penetration. Its already a hole, you just want to insert yourself into said preexisting hole.
Making a new one is probably a bad idea

What prevents Superman from being able to see through lead but not concrete?

If you’re talking about the neutron it’s because concrete has a lot of hydrogen. Alpha particles, beta particles, and light (gamma rays in this picture) interact with electrons, with the probability of being stopped increasing with electron density. Lead has a lot of electrons (its lower on the periodic table, called a “high z” element).
Neutrons, however, don’t care about electrons and instead interact with the nucleus, with the probability of being stopped depending on the spin state of the nucleus and the neutron. This doesn’t follow a specific pattern on the periodic table, but hydrogen has a big chance of interacting with the neutron while lead doesn’t. Cadmium, boron, and I think lithium 7 also would stop neutrons easily (there are more of course but those are what I remember offhand).

Nah, that’s not what they’re talking about. Superman’s vision is capable of penetrating concrete, but gets reliably stopped by lead. None of the particles here (or, I’m guessing, anywhere) have that property.

what do neutrons care about though? how do we appeal to that demographic?

Yet 2 meters of water will stop neutrons. Water is pretty cool.

Rato@sh.itjust.works 2 months ago
Sure, but just because it’s chock full of Hydrogen, which happens to be about the same mass as a neutron and thus takes up a lot of its energy per collision. Plastic, being a hydrocarbon, does the same thing.
That being said, water is pretty cool. You could use 2 inches of lead to stop 90% of gamma radiation, or 2 feet of water for the same effect. On top of that, metal is terrible at slowing neutrons (due to metal not being hydrogen), but that same 2 feet of water will slow down the neutrons by about 99.5%.

Hydrogen’s cool man. It’s just like, one little proton out there in the universe, with his Jiminy Cricket Electron buddy circling around all times, making sure he stays balanced. An unfathomable number of them, more than anything else.
porous_grey_matter@lemmy.ml 2 months ago
It is because of the hydrogen, but it’s not really to do with the mass, but rather because a “collision”/interaction is much more likely. For instance, ^58^Ni has the same likelihood to interact as hydrogen, while deuterium has only a fifth. ^135^Xe meanwhile has some millions of times the absorption power of hydrogen and it’s quite a lot heavier. It’s just not very practical as an absorber.

Yeah! Well if i get inside your body 🥵 (IF) I can rip your DNA to shreds unlike any of those other beta or gamma particles 😤

ItsAlwaysDNS@sh.itjust.works 2 months ago
Aren’t Gamma-Rays impossible to stop even with lead? You can only weaken them.
bingrazer@lemmy.world 2 months ago
Gamma rays are stopped by things with a lot of electrons, so a sufficiently thick block of lead will stop it

How much concrete do you actually need to stop a neutron with probability 1/2? Is 1 lightsecond enough?
