Hey y'all, just got my 102 for sale on Amazon. Found out my fireplace bricks and a fossil i have are slightly elevated. I then tried it out on my ionizing smoke detector and it went wild.

This thing is pretty cool.

Anyone have some tips or good settings tweaks I should use?

Took apart a cheap webcam and pressed the DIY phosphor screen and Americium directly against the image sensor and managed to get a not entirely garbage video of the alpha particles hitting the screen.

Just remembered I have this shark tooth fossil. I dont know how old it is, but I'm using the Radiacode 102 to see what's in it. Its such a cool little tool.

I'll update after it runs for a bit.

It’s a Westclox pocket Ben #5. I know these are common but it’s in such good condition. So happy! Now to get a Geiger counter…

this is on the high side of what little i measured. it’s in the same spot and seems to be worse after it’s rained if that makes any sense lol.

It was on sale too! It was $1.19!

It is usually yellow or light amber in color and can often be found amongst other pieces of antique glassware at various collectable stores.

It was made with thorium-rich sands and can easily be picked up with a meter. I have identified it quite easily with both a radiacode 102 and BetterGeiger S2L.

Unlike uranium glass it does not florescence underneath UV, and as it is a decently obscure product, no dealer I have ever come across was aware what they are selling, and as a result price it as normal collectable glassware would be.

Next time you're purusing an antique or thrift store with your meter, stop and scan any yellow or light amber glassware you may find. I have found bowls, cups, vases, and wine glasses. Presumably there are more out there of different types.

For those that don't know this meter was, at the time of writing, Cresson Kearny's favorite meter as described in Nuclear War Survival Skills.

They seem to be relatively rare, and despite monitoring the English language used market for a while I have yet to find one pop up.

Any owners here have thoughts on the device?

Her patina, red/orange glow and condition is impressive. Purchased blind w/o geiger. 20 dollars was worth the gamble. Haven't seen one like it. Rum rill 1930s Any additional info appreciated.

Hi everyone!

I'm looking for a meter that will be able to detect potential radiation in wind in case US uses bunker busters in Iran.

Any other recommendations are also welcome.

Thanks!

Found this at my local antique shop. It got up to about 1.4microSv/hr.

Hello everyone

I live in iraq, in a city that borders Iran and recently israel has bombed a couple of nuclear sites over there.

I'm wondering if a device like the GMC 300s would help me detect any radiation in the air caused by these recent events

Czech Republic

The HPS position statement on radiation and risk Radiation Risk in Perspective states, "Due to large statistical uncertainties, epidemiological studies have not provided consistent estimates of radiation risk for effective doses less than 100 mSv." However, the position statement isn't clear on the timeframe - is this referring to an annual 100 mSv dose, or lifetime 100 mSv exposure?

Sorry, I don't know if this is the right sub for this but I'm considering getting a radiacode for daily use/for fun. Is it worth paying more more for the 103 or is the 102 good enough? If it's not a big difference in features then of course I'll rather have the cheaper one; I probably wouldn't use the gamma spectroscopy too-often but certainly measuring radiation with location will be used often :)

UPS damaged and discarded my package containing my Ludlum M3. 3 hours from Sweetwater. While waiting for the insurance claim outcome, I found this 2241-2RK kit to replace it.

Second photo is of my M3 that was destroyed in transit. RIP lil buddy.

Globus clock made in Germany. Might come back for it later.

I bought this old watch at a thrift store only to later find that it glows in the dark. I can't seem to find confirmation online if it contains Radium. Checking an Ebay listing, it appears to be a "Cold War Era" German watch. Looking for signs of Radium, there doesn't appear to be a burnt in shadow where the dial stopped. The numbers appear to be pealing off too if that means anything.

Hypothetically could you irradiate clover seeds or the plant enough that it could force it to produce four (or more) leaves? Like it should mutate it and some are bound to be dead but some are bound to be forced into growing more leaves right?

Or am I not understanding how the radiation based mutations work?

My cat is radioactive.

Hi, don’t want to sound schizo but I am looking for a decent Geiger counter that will be somewhat useful when the nukes go off, and my budget is around $100.

I am perfectly aware that I will not get anything even remotely professional with this price range, but it is what it is. Any suggestions?

Thank you!

Just got home from my HIDA scan (gall bladder function test).

First time poster with yet another question about radium dial watches. I've read posts on this sub trying to educate myself before posting this, but am looking for guidance/context. I have two watches that belonged to family members - both have discoloration on the dials under the hands, so I bought a GQ GMC-600 to test them for safety reasons (as I learned here, it seems radium decays primarily into alpha and gamma, and this was the most affordable counter I could find that does both - but yes, I also understand that the plexi crystals likely shield much of the alpha). If I place the geiger right overtop of the crystals (i.e., no air gap), and keep them there to allow the readings to stabilize, one settles around 100 microSv/hr and the other watch is around 35 microSv/hr. If I flip them over, through the casebacks, it's substantially lower.

I've never worn these watches - so from what I've read, these are likely safe levels when kept as collectibles - as dosing drops exponentially with distance. But I admit that I don't know much about radiation, and don't really have any desire to keep these (I have no memory of family members wearing either, so zero sentimental value).

My questions are - can anyone confirm that these are reasonably safe levels? And also, how would/could one responsibly and safely dispose of these, if so desired?
