Gammas might be able to penetrate a little bit of concrete, since concrete has lower electron density than lead

Gamma rays are stopped by things with a lot of electrons, so a sufficiently thick block of lead will stop it

EDIT: higher energy light has more penetration power (so gammas are quire penetrating), but it’s a finite value

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).

I’m a radiation worker, I’m required to wear a dosimeter whenever I go into parts of the building near the nuclear reactor. This dosimeter is measured 4 times a year for radiation exposure. A few years ago there was a big problem because someone’s dosimeter showed a very large dose. It was found they’d accidentally brought it home and onto a flight. So two flights (a around trip) was enough to cause a bunch of alarms at a facility that actually monitors radiation exposure.

Even if they wanted to, a lot of PhDs take longer than 4 years. My program averages 5.5 (with 4 being very rare and considered “early”) and someone I know in physics say 6 or 7 is common. Those programs are going to have a large drop in admission. I’m on my way out and will finish at 4.3 years, I’m the first one in my class to graduate

I’d rather not live in a society where theft is necessary to survive

Yeah, the talesfrom[job] subs were fun to read. Tech support was my favorite of those type though. I looked for them here when I migrated but didn’t find anything (besides bots reposting from reddit)

I’d read the u/airz_23 ones, but I didn’t know they had a second account. I’ll have to go back and read those, thanks.

Also a ton of games have day 1 patches that you’d need to download anyway from their servers. I don’t recall seeing standalone installers for patches like we used to have. So buying a physical copy just makes you feel good rather than actually avoiding the problem with digital copies.

Two years ago when I built my new computer, there were something like two cases that actually had a slot for a disk drive. I did end up getting one for my older games and it is nice

T-Mobile. They don’t support the fairphone 6, but its worked well

This was the DC metro. I don’t know how strong of a signal you’re looking for, but I didn’t notice any differences compared to my previous iphone

I’ve used mine in a subway in the US, not tried parking garages

I got mine last year with the e/OS version (that’s what’s offered in the US). I have not used google messages specifically, but I have had trouble with RCS messages on the default messaging app

Thanks. I found it there too, but I was more surprised by the removal. It didn’t seem particularly over the top for them.

Did they delete this? Shows an error 404 now

Or micron reintroduces consumer ram while their competitors are locked into the bubble price. They then proceed to monopolize the market and things get worse

Or even canals
