Brute Squad posted:framing looks pretty good. I'm not so sure about some of the structural elements, but if a PE signed off on them, I'd be fine with it. Yeah the only thing about that is it looks like they ripped out the drywall, then decided the bare framing looked good. And then decided to live in it. Which is strange since it seems to not have a functioning shower or toilet. Also it's in the rear end-end of Appalachia.

If needed, you can hire someone to install a radon mitigation system (I think it usually goes in the basement?...not sure if it would help with venting out countertop-sourced radon). Yes radon is much heavier than air, so mitigation intakes go in basements. Usually under the basement floor. E: denser, not heavier. And my friend who deals with these things says they put it in the basement because most of the radon comes from under the floor, and there’s usually less air movement in the basement. So I was wrong pretty much all around Also all the “radon mitigation systems” I’ve seen are nothing more than a bunch of PVC pipe and one fan that’s on 24/7. And they cost between $1000 and $1500.

Jerry Cotton posted:Basically all granite contains uranium and thorium, which produce radon. So does the soil. Have any natural stone cladding? poo poo could have up to 4000 Bq/kg of K-40 in it. Brick house? 1600 Bq/kg has been observed in bricks. An adult human being contains more that 7 kBq of radioisotopes; sleeping next to another human being increases your annual dose by about 1 mrem. If you're going to seriously worry about cancer from granite countertops you're better off sleeping alone.

radon is radon, granite can release hazardous amounts of radon in some circumstances, caring about that isn’t unreasonable. you don’t have to be afraid of granite counters or w/e, that would be silly, but recognizing a generally-unacknowledged vector of one of the highest-body-count avoidable carcinogens as such and just being thoughtful in its use/installation is just “being not stupid” also: there should, like, definitely be some independent testing of this stuff, even if just to confirm that i’m an idiot, but also highlight that 1/1000 slab that’s Definitely Too Fissile and keep em out of households. which is the approximate standard we regard radon with in general to as it stands. even if it’s not a substantive hazard there’s still a clear issue with consumer awareness here Ambrose Burnside fucked around with this message at 21:18 on Aug 21, 2019 |

Jaded Burnout posted:I'm honestly a little baffled by this refrain. Either you have an odd way of cooking burgers or you are bad at detecting grease on things. I can feel and see the grease on my spectacles after cooking them. Same with e.g. taking hot roasting meats / veg out of the oven, stir fry cooking. We are not all collectively imagining the problem. Happens the same way regardless of extractor, though is lessened by a good external venting one.

Look at all you Schills for Big counter top. GRANITE CAN KILL YOU AND MAKE YOU AUTISM!! I always liked Granite counter tops, even before it became the IN thing to have in your house. I have them in my poverty spec condo. Would like it if it was a brighter colour though. Or a fancier looking pattern. Too dark. granite is my favorite rock and I'm such a fuckin nerd

I'm not saying it's a non-existent problem, I'm just saying that "people with open cabinets must not cook" isn't the answer either, because I do cook and I have open everything and don't find it a problem. So there must be something else going on.

Ambrose Burnside posted:my fave thing about granite countertops are that they often offgas radon and the granite industry absolutely refuses to acknowledge it or offer any sort of testing because there’s no legal requirement to do so and independent testing has found examples that are straight-up hazardous if not used in very well-ventilated spaces and there’s no way to verify that your granite countertops aren’t giving you lung cancer aside from testing after you’ve bought and installed the things Radon is a problem in basements because the cubic kilometres of granite underneath can generate serious amounts of radon. One cubic metre of countertop is generating such a small amount of radon it’s not a concern. It will be generating a measurable amount of radon, and that’s why the industry doesn’t want testing.

Leperflesh posted:I don't wanna just let this pass, in case anyone doesn't know about electricity. As my old teacher used to say, "it's the volts that jolt, but the current that kills." In other words you cannot evaluate whether exposure to a particular electrical charge is dangerous solely by looking at the voltage. The trick to arc-welding is that you the welder have a much higher resistance than the metal you're welding, and the current will flow where it meets the least resistance. You will get zapped if you're a dumbass and weld on wet ground with no gloves, because the current will seek ground over the neutral return if there is less resistance that way, but generally it only takes being bitten once to learn better. Also, if you're just tack welding, a helmet isn't strictly necessary, because you can just close your eyes and make a quick tack. But a tack weld is temporary and takes minimal load, you'll want the helmet when you weld the tack up. I watched my grandfather weld steel floors in trailers sans helmet by reaching under with the electrode and control the weld by watching the opposite side of the weld pool from above.

They were likely phenolic resin because of the age, but epoxy is probably more common now. Epoxy resin counters with epoxy painted concrete floors sounds pretty loving durable to me. quote:Anyone else as broke-brained as me? I think I first heard about the benefits of doing that in the 90's on Usenet. Proto-goons have been fantasizing about lab-grade countertops for a long time.

Nevets posted:When I bought my new house the kitchen countertops were advertised as 'green marble' but I think they are actually a kind of serpentine. The quarry is less than 50 miles away, give or take, so I'm pretty certain I made a bologna sandwich this morning on a slab of gemstone Serpentine is sometimes used as a gem, but so are the quartz and feldspar that make up the majority of granite. Gems all the way down. Chrysotile asbestos is also a form of serpentine (it's a weird little mineral family). Yours is probably made mostly of lizardite (the name is a total coincidence).

Blindeye posted:I would love black soapstone like a chem lab. Anyone else as broke-brained as me? I thought lab tables tended to be black slate. Personally I like granite and natural stones a lot, but that's probably because that's what I do for a living. The one thing that I've seen recently that I like a lot is that the quartz versions of natural stones are getting a hell of a lot closer to the real stuff. So you can do a white marble kitchen counter top without worrying about it staining as easily as real marble does, plus it takes an edge way better than natural stone so it miters up beautifully.
