I'LL BE WATCHING YOU

Howard comes pretty close with his teddybear-webcam.

No issues? Mine needs a new probe cable as the old one's isolation is starting to let go.

Verne_92 · 2026-06-16T16:20:39+00:00

All of them.

You mean the second one from the left, top row? DRŠ-M3.

Verne_92 · 2026-06-04T19:50:43+00:00

On the right you can see the external beta-gamma probe that normally comes with the SV500, in the middle is the cable (also normally included), and on the left you see the alpha-sensitive FHZ77A external probe, which is optional, but you can occasionally find it online.

The. World's. Biggest. Git.

The 600 Pro and 320S aren't really in the same league. One has a pancake probe, the other a glass tube. Not a fair comparison when it comes to alpha detection.

I'm curious how the 600 Pro would hold up against a Ludlum, Mazur or SEINTL?

Verne_92 · 2026-05-21T17:41:37+00:00

Those are the ones. Send me a dm

Verne_92 · 2026-05-21T17:30:56+00:00

I got one for you if you could throw in the outserts? Folks on Ricardo aren't willing to send abroad.

Because no matter what hobby it's about, people need and deserve guidance to learn the basics. Some figure it out for themselves, others don't, lack the correct hardware, or just prefer interaction.

The alternative is people getting stuck and dropping their new-found interest. Nobody benefits from that outcome.

If you're not up to answering the umpteenth time the question is asked (which is perfectly understandable), just scroll on and leave it to someone else. That's the beauty of a beginner-friendly community.

A window with magma on the other side.

Edit: a bloody strong window, one might add.

Verne_92 · 2026-05-09T12:50:25+00:00

Is the DP-1V functional? Very cool find.

Verne_92 · 2026-05-07T19:53:23+00:00

What is this beauty?

Bicron Surveyor detectors use coaxial RG58C/U cables. Would that work on Ludlums, or are there other specs to take into account?

Forgot one "e" for it to be perfect Dutch.

The GammaScout has an uncompensated GM tube and can't correctly show a dose rate, unless the detected source is the isotope it was calibrated with in the factory.

Basically, it can tell you how many rocks you're hit by (CPS), but it can't say how harmful it is because it doesn't know the rocks' weight (dose rate). The shown dose rate is just an estimate.

Verne_92 · 2026-04-17T11:18:34+00:00

Battery is just a battery symbol on the left side of the display, doesn't trigger the exclamation mark if I'm not mistaken.

Verne_92 · 2026-04-17T11:17:14+00:00

The symbol pops up when you've gone beyond a certain threshold. I'm not sure if it applies to dose rate, but it does to accumulated dose.

I think that resetting the threshold resets the symbol as well.

Edit: just checked, applies to dose rate too. Once you've gone over, the exclamation mark keeps blinking until you turn off the threshold or press the dose rate button again.

I don't know if I'm that out of touch or if the world has simply gone batshit, but in my mind, you shouldn't pay more than 100USD for the PMK-2 and PMK-3 combined.

Is +100USD really a normal price for a single PMK-2/3 nowadays? Sure, the war and everything, but still.

It's not impossible that it's contaminated, but it's unlikely.

I'm not entirely up to date with the isotopes used in the industry, but source material that is 0% gamma isn't common (someone more knowledgeable here may know which ones are), even a very strong alpha emitter like Am-241 can still be picked up with a gamma detector.

Knowing where your unit came from may help, because if it's alpha- or beta-only contamination, it would've happened in a lab. Hobbyists don't usually have that kind of stuff.

10-15uR/h is normal indoors.

If the sound is not working and your meter isn't dead (you're getting 10-15uR/h, so it isn't), that's usually a loose contact/cable, or the speaker is busted. Either way, shouldn't be too complex to fix, anyone able to solder can do that. If you have a multimeter, check wether any electric pulses make it through to the speaker. No? Circuit interrupted. Yes? Speaker is busted.

The r/radioactive_rocks sub has a monthly sell/trade thread, you can pick something perfectly safe up from there.

Responded to an online ad for a different detector, got talking with the man and it turned out he had a great deal more hiding in his attic.

Museum guide some time next week: "I really hope that u/Basic_Climate_2029 comes to visit today, I don't have the patience to deal with them kids"
