idiot here. can someone explain to me how come neutrons can’t penetrate concrete compared to lead.
Another idiot here who found this answer interesting: https://www.quora.com/Why-is-concrete-the-best-shield-for-neutrons
that’s very interesting, thanks.
Neutrons need something that provides them with lots of chances to have interactions. Water is good too. What blocks neutrons may not block gamma and vise versa. To block neutrons and high energy particles like cosmic rays that actually have mass to them you need something like a crash barrier.
Same. Aren’t neutrons capable of crossing the entire planet unless they directly colide with another particle?
I reckon you’re thinking of the neutrino which rarely interacts with matter.
I believe you’re thinking of neutrinos. Neutrons love bonking into things, and they’re really good at it. Too good; if the thing they’re bonking is too big they’ll just keep on bouncing, so you gotta bounce them off small stuff. Concrete has lots of small stuff bound up in it, so while there’s better shields (borax and paraffin slurry is a classic one) there’s few cheaper or easier to make shields than concrete.
Oh oops. I did mix them up.
Neutrons are just so bonked up
If you throw a ball at a brick wall it will bounce. If you throw a ball into a ball pit it will be slowed down and stop
What about z-ray? It’s two more than x-ray.
If you have to ask, you can’t afford it.

This is clearly evidence that Jimmy Neutron is the peak male form
What about couches?
Proof that alpha males can’t hit themselves out of a wet paper bag.
Uhm… Putin uses the n-word…
What about sigma particles?
