Build Your Own Geiger Counter with MightyOhm's kit
https://mightyohm.com/blog/products/geiger-counter/
@ai6yr What kind of calibration can be done? I TLDR manuals, would want to knowdynamic range, from minimal baseline sensitivity to max usable input.

☢️ Radiation monitoring
Today's reading: 0.26 µSv/hScale:
< 1 µSv/h – don't worry
1–10 µSv/h – OK briefly, not long-term
> 10 µSv/h – take action (limit time)
> 100 µSv/h – genuinely dangerous (leave)
> 1000 µSv/h (= 1 mSv/h) – high risk for longer stayWhat I measure:
– gamma (γ) radiation
– beta (β) particles
– X-ray radiation#RadiationMonitoring #GeigerCounter #NuclearSafety #BackgroundRadiation

Radiační monitoring
Dnešní stav: 0.31 µSv/h
Škála:
< 1 µSv/h - neřeš
1–10 µSv/h - ok krátce, dlouhodobě ne
> 10 µSv/h - už řešit (omezit čas)
> 100 µSv/h - už fakt nebezpečné (odejít)
> 1000 µSv/h (= 1 mSv/h) - vysoké riziko při delším pobytuCo měřím?
– gama (γ) záření
– beta (β) částice
– rentgenové (X-ray) záření#RadiationMonitoring

Voila! Geiger counter drawstring bag! (Wrapped in a plastic bag, because of instructions not to contaminate the tube with radioactive dust... not that I have any here. 🤔) #sewing #geigercounter

LOL I believe the WW2 era radio behind me has a tube with some radioactive components. It clicks almost as much as the smoke detector if I put the detector in the right place. #radioactivity #geigercounter

Geiger Counter Fun
Well, at least, my garage is not extra radioactive 😂 Not at all above background, actually, it seems.
(always wondered that given my random radio gear and parts....)
-
Interesting, so the most radioactive things here at my house (only slightly above background, not terribly radioactive):
1. Granite countertop (this is a known thing)
2. Night lights (apparently, tritium in there to make them glow)
3. Smoke detectors (bit o'radioactivity in there)
4. Rebar in the garden (hmmmmmmmmmmmm... apparently some radioactivity in the stream, this is where it's shown up in massive contamination events in the past, i.e Ciudad Juarez and the radioactive Taiwanese apartments).
5. Maybe (tough to tell) -- some of the newer drywall. Only slightly more active against it, not a lot.What provides far more clicking was standing out in the sun. LOL

Hmm, the most reliable clicky thing in this house is this night light. Are these things radioactive? #geigercounter

Geiger Counter! Fun project for the afternoon. Project kit from @mightyohm

Correctly assembled. #geigercounter #electronics

Geiger counter project! (Or more accurately, Geiger clicky thing). Did this outdoors. Which I have decided is much better for your healrh/lungs than the garage or workbench. Photos... #geigercounter

☢️🥒 Behold, the Flipper Zero Geiger Counter—a #gadget that lets you graphically watch your daily dose of #radiation, because why not? Now you can obsess over #CPS and #CPM like a pro, all while pretending to be a radioactive cucumber. 🌟📉

So, i'm browsing Micro User #34 (the premier BBC Micro magazine), and its a whopping 220 pages. Thicc mag! Granted that is a December issue, presumably packed with all the games released for the critical christmas holidays. Issue 42 is in August and presumably a more normal size. It's still 164 pages!
I offer here a detail from the cover of Issue 42 which, if your timeline is getting a bit too demon-core-y, might be of interest: DIY Geiger Counter!

Checking in on Minion’s radiation levels. Setting is on 10x, so he’s at 3 mr/hr. Still too high to sleep with us, but he’s resigned to sleeping with his emotional support Geiger counter. #catsofmastodon #cats #lynxpointsiamese #geigercounter #radiation

Lots of new faces at Tog this Tuesday! We broke out the Geiger counter, and turns out Gary’s lunch was radioactive. ☢️🍌
Here we are testing a banana for science 🍌📈

#Ukrainian #President #Zelensky has said he will travel to #Turkey's capital to meet President #Erdogan & will be available for direct talks with #Russia’s #Putin in Istanbul on Thursday.
"We will do everything to ensure that this meeting takes place," he told reporters in a hastily-arranged briefing in #Kyiv
‼️Be careful. Take full security, don’t accept eats or drinks, take a #GeigerCounter, wear gloves - Russia’s #assassins have a nasty bag of tricks. #USPol #auspol

small update:
compared to the "official" local radiation measurement by Deutscher Wetterdienst my device showed slightly higher values.
@nocci found out that the conversion rate for the #J315 tube inside the #GeigerCounter housing had to be re-evaluated and fixed.
Now I am using 0.0065 and my values are down to the values the official station is recording.
🎉

👨🔬 So now you can play mad scientist with #Python and a radiation detector! 🤦♂️ Because clearly, what the world needs is more people turning their laptops into Geiger counters via #USB or *drumroll* #Bluetooth. 📡 Just don't blame us when your "research" sets off the neighborhood alarms. 🚨

Need advice: want to clean up some white and light yellow-ish deposits on a partially working circuit board that’s probably about 30 years old. Turns on but doesn’t register events from the Geiger-mueller tube.
My idea is to gently scrub where these deposits are with a new soft toothbrush and isopropyl alcohol and wipe/clean with cotton swabs.
Board measures Alpha, Beta, and Gamma radiation using a small LND-INC 712 tube. I’ve confirmed it’s getting 488V.

Heute ist mein Kerzenständer mit Uranglasur angekommen.
Natürlich habe ich das Teil direkt mal vor meinen Geigerzähler gestellt.Die Ausschläge sind erheblich höher als beim Uranglas. Maximum lag bei 1573 CPM.
Zum Vergleich, das Maximum meiner Messung einer Weinglases aus Uranglas lag bei 164 CPM.#Flipperzero #geigerzaehler #geigercounter #diy #Uranglasur #strahlung #uraniumglaze

Mein Uranglas ist angekommen und ich habe direkt mal Messungen mit dem Flipper zero Geigerzähler durchgeführt.
Höchster CPS Wert lag bei 8 und CPM bei 164.
Hintergrund Strahlung CPM lag zwischen 15 und 27.#Flipperzero #geigerzaehler #geigercounter #diy #Uranglas #strahlung
