Aranet radiation sensor - test and teardown 

Even more saaaalt

The whole room vibrating ​@@the_danksmith134

Even more Diodes going to go wild!!

THE ROOM IS SHAKING NOOOOW

LMFAO🤣

Literally came here to comment this

That's awesome!

I wish I had said that!!

Ooosh!!! Arent u just in fine form today 😅 im v jealous!

Lol ! excellent drama I loved it.

What you need a CO2 sensor for? Serious question. A CO sensor is great if you have a wood stove in your room. But a CO2 sensor makes no sense at all unless you run a professional greenhouse.

@@albinklein7680 CO2 sensor can for example be used to monitor/meter amount of ventilation. Too low ventilation and too many people => CO2 levels get sky high. It is an indication to increase ventilation. CO sensor is a safety device, very rarely CO2 sensor is and when you have a suffocation risk due to CO2 you want something more robust than Aranet.

Yes i wondered the same! But obviously there is a non industrial market, even if niche, for sensors such as these. I can see maybe new baby owners, health purists, and the ignorant paranoid investing in these, but thats all. Did u get yr co2 one for any real or perceived co2 threat, or just cause its a nifty and interesting device?

@@albinklein7680Because all humans breathe out CO2, and some humans who are infected also breathe out viruses (covid, flu, measles etc.), the CO2 reading is one of the simplest ways to estimate your risk of getting infected in a certain place. For example if you haven't been burning things, and the reading is 800ppm, then 1% of the air you are inhaling has recently been inside someone else. The reading outdoors is normally about 420ppm. If the reading is 2500ppm (like in a lot of schools) then 5.5% of the air you are breathing has recently been inside someone else. If the reading is under 500ppm, then the ventilation is very good, like in the parliament building after they upgraded the ventilation early in 2020, before deciding that they would not upgrade the ventilation in the schools.

And you haven't got the message yet !

@@andymouse wut?

It means if you have tried 7 times maybe its time to stop because he's to busy or something like that @@ancientlink0

​@@ancientlink0 I think he used to make some videos and article about his GU-81 VTTC

@@TranNhan06 i saw it on his website, i wnat him to make a series like the sgtc or sstc one, with lots of info and a general guideline dot making vttc or drsstc

Check his web site.

@@andymouse I have, but a video would be better than text

In addition, the scales are weird, the yellow one covering from 0.2-10 uSv/h is not a great design.

Agreed.

Maybe its for people living in radon areas?

@@joinedupjonThis is not precise enough to measure radon levels. Its very little radon all things considered. It affects humans more than something like a chunk of uranium ore sitting on the shelf because we breathe in air all day. most types of radiation don't penetrate the skins, but when we breathe radon in, we already got it into our body. And even for something like gamma rays, the power is calculated with distance CUBED, so a radiation source right next to you or even inside you(like radon) is much, much more powerful than one just a few meters away.

The biggest thing I see that makes it not very useful is the inability to measure larger radiation rates and doses. To me, this device is a disaster/war device. Being able to measure only up to 100 mRem/hr and a total of 100 Rem is not very useful. Those rates and totals are below the threshold that threatens health. You need to be able to measure up into the range where acute radiation sickness symptoms would appear. For this purpose, it needs to measure up to 100 Rem/hr and 1000 Rem total. Those are the useful numbers that could assist medical staff in treating the ARS. Otherwise, it's not really useful in a disaster scenario.

It was uploaded one week before this as well and is not listed. Maybe by accident 🤔

​@@Electronichub_05maybe just the pateron thing that he just put 10 days ago this vid and posts now beacuse if you get pateron you can get videos early

In todays Chernobyl, you should be more worried about unexploded ammo than radiation.

Well, a lot of bright/deep orange ceramics from before the 1960/70s are radioactive, see "Fiestaware", but is not the only brand..

@@steafra In late 70s, Intel has problem with radioactive ceramics for memory chips enclosures but cups...

@@ntfshard uranium salts have beautiful colours, so they were used in glazing before figuring out that it is not such a great idea. There is also quite a lot of old "yellow/green" glass around that is pretty radioactive. you can see some in this video too. The emission is not very dangeraous, the greatest risk is for people actually working in making the ceramics and the glazes, or the glass.

When the radiation spikes no one is going to tell you.

I love when people state the exact same thing you just said back to you.

Make profit with fear.

Especially in schools and othet crowded rooms CO2 level can be a good way to determine when to have a break. ;)

Eh. that's kinda normal. No device on the market, literally no device, will detect all types of harmful radiation.

@@jort93z Ok, I'm not a radiophysical expert, and happy to be corrected. But I have used hand held devices in my occupation as a professional geological surveyor, where using a vacuum tube detector that will record radiation across a wide spectrum, smoke detector isotopes off the scal!! natural geological occurrences (potassium, uranium isotopes,..) There is of course a vital difference between instantaneous exposure, as in a patient undergoing dental X-ray, and long term exposure in a nuclear facility. So where does this device fit in a world of professional experience??

Alpha has very low penetrating power, probably won't pass through the skin, the big danger is if an alpha emitter is swallowed, allowing the radiation directly into the body.

​@@mikemccormac9368glass already stops most alpha and beta radiation. So if it was a normal vaccuum tube(i presume you are referring to a geiger-müller tube), it would not detect alpha radition. Doesn't penetrate the skin either, mostly an issue if ingested. If you want to measure alpha radiation, you need a special type with a "window" at the end. This windows is made of mica or a similar material in order to allow radiation to pass. But it'll also only work if you point the window at the source. However, since you mentioned Americium 241, keep in mind that Americium 241 also produces some gamma radiation which might be detected. There are some metastable results in the decay chain, which emit gamma rays when they decay to a lower energy state. You need to consider the whole decay chain, as you will never have 100% pure Americium 241, it will immediately start decaying into Neptunium-237 and so on. There are other types of harmful radiation as well, UV-C for example, which a geiger müller counter can't measure at all.

Nice come back !@@mikemccormac9368

Thats 'E-Ink' for you. Thats par for the course.

@@andymouse hmm ok. Its too slow to me for a measurement device.

Yes it is . They are seen as greenhouse temperature gauges and stuff with 15 minute refresh rates.@@maxcompress9732
