Based

true fallout is just particulate, but in the context of fallout, it is radioactive particulate.
It's more dangerous because it is radioactive not because it is a fine dust.
You might not breathe it in but it can still harm you.
It's possible there are borated polyethylene NBC suits out there to give radiation protection.
The eyepiece lenses would be made of clear lead acrylic.

I understand you need a suit, I was just wondering if you really need NBC filters instead of a particulate filter for any reason.

Doesn't Oppenhemier say thats it's safe to go outside after three weeks?

That's pretty much true yeah.
I think it has something to do with the half life of most radioactive materials degrading near completely at that point.
I think it has something to do with the size of the radioactive particles being too small for normal particulate filters to catch. By the nature of activated charcoal it absorbs those contaminants before they can pass completely through the filter.

Opp, if you ever want to come and clear some stuff up for us, feel free to do so.

P-100 filter on a full face respirator would work just fine.

late to the party but it's the 7:10 rule where for every factor of 7 in time, the radiation goes down by a factor of 10

this is my question as well. where tf am i supposed to find non-expired 40mm screw on filters for an israeli gask mask. they're nato standard but i can't find any new non-asbestos filters.

Try amazon. they go for ~$30 a piece. better to get a bunch of russian ones, it's not like you'll use them enough to worry about asbestos.

If thats the case, then why not arm every American citizen with a gas mask and start bombarding every other country with nukes? Because gas masks don't stop particles that size.

Jesus fucking Christ user, that is literally the most perfect way to commit suicide that'll take effect 15 to 30 years down the line

It's a lot better than nothing, your effective dosage goes up by a magnitude if you breathe in the dust compared to just exposure through skin

I wonder if this "you need a gasmask and a full chemical suit to survive" is just prepper vendor marketing. I bet a simple respirator mask you find at a hardware store would work

Personally? I would go for the m45. The 40 is far more practical, more available, and has way more attachments, but the 45 is a rare helicopter pilot mask that I've yet to see under $100, they usually go for $200-300+. It's one I've wanted for a while.

That depends on how long you want to survive where and with what other measures taken to protect you.

It would. Better, even. Pair it with a Tyvek suit, you have some reasonable protection. Now, to just get the training to use it and the decon infrastructure to survive using it.

I'm no expert but I believe you would do OK with a respirator/gas mask and a raincoat along with uncontaminated food and drink, you need to sit tight until the hotter isotopes have decayed enough and after that it's dodging the less hot alpha and beta active particles which are hidden in the dust and primarily pose a hazard if they get inside you. If you take a near-direct hit from modern chemical weapons you are dead anyways since you cannot effectively decontaminate yourself even if you survive the initial 12 hours

Find me a single instance where someone got mesothelioma from a gas mask filter. You can't, because it never happened, because it's not actually a problem.

You can't because people get sick and die 30 fucking years later you moron. No one is going to be aware what exactly gave them lung cancer.

>gets very specific type of lung cancer
>doesn't know what gave them very specific type of cancer that only one thing causes
Try again faggot.

In a cbrn situation how well would one of those 3m clear faceshield masks protect you?

Their bayonet lug filters don't last as long, but in theory they do the same job.

dude, if you're outside in a nuclear environment, you're already fucked. don't do that shit.

Israeli masks use 40mm stanag filters
Find a something labeled "nato filter" on ebay for like $8.
>new non-asbestos filters
they don't have asbestos in them idiot

I don't know where you guys live where 30 dollars for a filter is typical but don't do what that other guy said. And don't buy Gost pattern filters (Warsaw pact type) for your Stanag mask (Nato).

Where do you idiots get the idea that gasmasks have something to do with asbestos?

>Fallout is just dust after all
Fallout is not just dust, it is a catch-all term for a variety of lingering effects from a nuclear explosion, and your 40-year-old surplus Soviet gas mask with a filter that only had a shelf life of 5 years will not help you anyways.

Can't wait for the nuclear war to actually happen so brainlets like you and 95% of preppers who have absolutely no idea what they're talking about can all fucking die.

Asbestos isn't the only thing that causes mesothelioma

i hope you all like looking like retards when you tell your doctor that the reason you have asbestos in your lungs is because you like gas masks.

>t. triggered mask autist
if you want kill your lungs, fine by me. but im going to laugh at you all the way.

>Where do you idiots get the idea that gasmasks have something to do with asbestos?
Retarded meme about old soviet filters having asbetos in the particulate filter.

Laugh away user. Nothing's going to happen.

then stop using 50 year old filters

Breathing through a compromised russian mask is a death sentence you braindead mong. Have you ever handled asbestos in a professional setting?

What do you mean retarded meme? Russian filters have asbestos in them, I can cut one open to show you if you are too stuipid to belive me. Newsflash, 50 year old anything isn't stable and the asbestos fibers can easily have degraded and turned into a particulate.

People who think all filters have asbestos are still idiots though.

No dude, you're the idiot.
50 years ago it wasn't called Russia. Stop trying to trick people into thinking all gost filters have asbestos in them when the last recorded evidence of a Soviet filter using asbestos was in 1979.

I haven't, have you? Do you even know what asbestos is? Do you even know under what circumstances it's possible to breathe in asbestos fibers from a gas mask filter?(assuming it has it in the first place)

I fucking hate it that every gas mask thread turns into mindless shitposting and fear mongering about a rock.

By the way, although I'm not sure about this, I suspect that the "shelf life" of activated carbon or activated charcoal products is for regulation and safety standards rather than the real usable lifespan of a product.

>What do you mean retarded meme?
>some autism about asbestos fibers breaking down
1. I mistyped. It is an autistic meme, not a retarded one
2. asbestos fibers can easily have degraded
no they cant. Asbestos fibers don't degrade, asbestose textiles degrade into fibers.
3. go ahead then, cut it open. show me the asbestos nigga.

THIS.A

Ok you pedantic fuck, let me be a little more clear.

Russia is still issuing the same exact SOVIET filters that they made 50 years ago along with modern filters because they made a metric fuck ton. Their filters have always had asbestos because it's the same fucking surplus. The GP-5 filter that they give out with the GP-5 mask that is STILL ISSUED

youtu.be/RDsG_3dQaUo

And still nobody has died from it.

NBC guy here. Almost any mask you have is better than breathing in any agent you can think of without one.

>more clear
>uses the misnomer "Gp-5" when he means SchM-62m
lol

Yeah, because a cotton prefilter is an impossible cost to the manufacturer even after they know that asbestos is hazardous once it deteriorates. I don't even think anti-russian shills would go that far.

But you're legitimately wrong on a couple of reasons. They only use the SchM-62m is only used for training. They have developed newer respirators that they issue currently. The Russian military currently uses a mask in the PMG series. Also they didn't make millions of filters in one span of time and then just abandon their factory, never to make improvements to the design again, that's just stupid. There are markings on gp-5 filters that tell you the year it was manufactured.

>um yea, so I fink that the mask isn't so good. So it may or may not contain asbestos but I don't reeally know. I'm a big youtuber 'ere and I know wots best.
that guy is full of shit. The only useful information he gives is about the polish fp-5 and ws-4 filters.
>blue asbestos
that's just as retarded as saying blue meth is more important. A fucking dye doesn't make anything more deadly.

Okay, let me give you a word of advice here.
One, stop being poor.
Two, buy a new production filter; they're like $6 USD shipped on ebay or something.

Blue asbestos is a type not a dye you complete fucking retard. "that guy" is from Jow Forums and a respected gas mask poster

I'm sure he's well educated.

You're the one who wasn't even aware that there are different types of asbestos with completely different properties. You are in no position to be criticizing someone's video on asbestos when you don't even know something as simple as that.

You got me there. And also I realize now that my analogy of meth was wrong too. The reason meth can be made blue isn't due to a dye, but rather impurities.
I had no idea that asbestos types could have completely different chemical formulas and different structures. So yeah, I was being a shit head in that regard.

But I'm not lying, here's a source I found from some Finish scientist dudes. It's not that hard to read and it shows all the different filters they have tested that have come up with asbestos in the pre filter.

>tfw my m95 is already having problems
When unscrewing the filter from the mask, the threaded hole it screws into starts spinning around and you can't remove the filter. The only way to get it out is to hold it from the inside and unscrew it. If I screw the filter in really tight I can get it to stop spinning but now I can't remove filters one handed. I'm fucking pissed I wasted my money on this piece of trash.

Any suggestions on a good mask? I'm thinking an avon c50.

Activated carbon has the ability to "latch on" to other mollecules using free valence electrons. Over time any molecules that leak into a carbon filter will take up those free spaces, and the filter will eventually be useless. They do have a shelf life depending on how well they're sealed

>really activates my carbon
Thanks for the clarification.
So is activated carbon just another word for carbon?
I did some quick research and it turns out that carbon attracts polar and inorganic compounds but I'm not yet sure why.

The M40 is the predecessor to the avon 50 series masks and it pretty comfortable as well as having lots of replacement parts available just in case you ever have problems like you have now.

It attracts everything, thats why its the building block of life. Activated just means its been "cleaned" of all attached mollecules. You can reactivate filters with high heat assuming theres nothing to dangerous that would burn off

>dtic.mil/dtic/tr/fulltext/u2/a179114.pdf
primary source info
short answer: not to direct respiration that you are thinking of: the psd is enormous and no media with life supporting flow rates is going to catch enough

long answer: the problem with radioactive dust is that it is radioactive. even if you dont breath it in, it accumulates in the filter, you are concentrating a source of rads through the mechanism of the mask itself. the goal with radiation is exposure, the dust isn't acutely toxic by respiration, it is instead the net exposure time.. current event exposure isn't changed at all, deposited dust will extend your dose after your event exposure but if you cap limit you're cooked anyway

Yeah, really high heat. I'm looking at the wikipedia article of its reactivation.
So I guess that absorption is just an inherent property, there doesn't seem to be any obvious chemical reactions that go into it. It has something to do with its massive surface area I'm sure.

its a statistical phenomena
the potential energy of carbon suface adhered to a given contaminant is very close to the potential energy of carbon and the contaminant by itself, because carbon presents so many different polarity options on a crystal lattice (theres a great deal of pi electron movement, so the electronegativity of a given bit of surface can be stabilized by the entire chunk) as well as being "roughly" nonpolar and easy to produce in high surface area (carbon black/ ultra high surface area charcoals etc) so the statistical chance of a given contaminant becoming bound to a carbon gets very high unless they are extremely polar, which most organics (ie almost everything) aren't

That would explain why filters are so thick too.

You can buy radionucleotide filters . I wear a full face respirator for work and keep a few laying around the house for SHTF situations

Remember folks, you only get 8 work hours out of a rated filter. After that you're only partially protected

Thats assuming you dont run into any gas or moisture issues. i would say 6 hours to be safe, and change them asap after gas

Anyone have a PMK-2 they'd like to sell? Preferably with a safe filter?

Correct. I'm an asshole and don't change my filters often enough. I run P100 and the company issues N95. Based on my hours worked I should change them weekly but it's more like every 3rd week. That's no bueno
