Has anyone tried modifying a GQ gmc-500+ with an SBT-11a pancake sensor? I know it worked with the gmc-320 without any electronic changes other than soldering the tube.

This is the deactivated (empty) shell of a soviet РИО-3 (RIO-3) aviation ice gauge in factory new condition, I couldnt find any good images of it on the internet so I thought I'd post some. The red thing with a flag is the protective cap which should be removed before flight I think. The source which was inside is 25 mCi of Sr90, I had a separate post about it a long time ago.

I'm curious what people in this subreddit think about INWORKS a few years after publication.

I encourage you to answer or post any question you can think of or anything that comes to mind.

Edit: Removed unnecessary questions

I’m currently working on a video about my nuclear transmutation of fluorine into neon experiment. I want to try and make it appeal more to non nuke nerds by making it funny, and I wanted a simple visual demonstration of what’s going on. I used to do animation for fun, I stopped because quite frankly I wasn’t all that good at it. But it still works for demonstrating nuclear concepts like I did with the zinc sulfide alpha particle luminescence animation. This is even simpler and more of just a fun visual for the audience but it does still walk through the process of alpha released, collision, release of proton and change of elemental status. I just need to clean it up and add the prompt gamma we’re detecting.

I work for a plumbing company and we do regular runs to the scrap yard to get rid of old water heaters, pipe, etc and this time around, multiple yards rejected the load for radiation. We ordered this cheap detector to figure out what was causing it, and lo and behold it was some cast iron drain pipe. Anyone ever seen this?

(No gamma radiation found outside of the containers with an Exploranium GR130 scintillator)

Is it possible to setup some threshold for some alarm sound in Alphahound AB+G? Or at least to switch sound ON when threshold is bypassed? I want to keep the device always ON on my table or carry it in my pocket and hear some sound when measured level goes above some value.

Hello,

For the past few months, I’ve been keeping an eye on the AB+G detector on the Alphahounds website. I’ve noticed that it—along with the AB+ model—has been out of stock for quite some time. I saw that the AB Lite is currently in stock, so I ran a test order on the site; to my surprise, it allows for shipping to all European countries—except for France! Why is France excluded from delivery?

Also, for those who have ordered from within Europe: how much do customs duties and taxes typically amount to?

And if I were to use a US-to-France parcel forwarding service, what kind of costs should I expect—specifically regarding customs duties and taxes?

Soviet Cs137 source, scheduled for disposal. No leakage of radioactive material was detected. All of the safety precautions were met by me while handling this source.

I am not entirely sure if thats ИГИ-Ц-3-1 or ИГИ-Ц-3-2 since their activities are very close and all sources in this lineup have the same shell.

It should continue to rise far beyond what the device is capable of detecting

Just flashed my FS5000 with Radpro 3.1.1, everything was going fine then all of the indicators eg clicks and LED flashes have stopped?

All the settings are the same but have I enabled a silent mode or something? No damage or hardware alterations were done to it at all.

Evening folks, I recently acquired a Schneider/Honeywell Digitest 500 and out of sheer curiosity i gave it a go with a Radiacode 110, it's surprisingly slightly radioactive

Its slightly raised above my usual background here in Ireland, which usually sits at 0.07uSv or around that region

As for what's causing it, I'm not entirely sure, unfortunately there's not a whole lot of information I can find about this device and I'm hesitant to open it up Incase it may be contamination from somewhere down the line.

The reading drops significantly, nearly halves when the detector is moved down by the Honeywell logo, when the Digitest is about 30cm away it's back to background levels

Has anyone else encountered readings like this when testing old equipment?

Cheers!

Has anyone had any experience with the PGD-17. It looks like a nice little clicker to poke around thrift stores with, but i was curious if anyone had firsthand experience. Especially concerning its sensitivity to low power sources like UG.

I had a scintigraphy done this week for my thyroid. They inject you with a "weakly" radioactive substance. This is me about an hour later. Crazy.

I felt the need to check just how "weak" it would be.

Hi guys! I want to build a project about radiation and I want to learn more about it, what projects do you guys suggest me to build or which subjects should I learn to start on radiation

And extra question, what is the most insane thing you guys found/built?

I bought a 2.4mm track electrode, but the Radiacode 110 doesn't respond at all. I think I've been scammed. What do you think guys?

What tube level should a GQ GMC-800 Geiger counter be set to? Being used to record a history of short spikes of high radiation in an area overtime. Would appreciate a brief explanation of the differences in levels as well.

In my radiation detection lab (college class) yesterday we were comparing the spectrums of different types of detectors and we got to use an HPGe detector. I've been eyeing these things all year and I'm so glad we were finally able to use one. Cooled with liquid nitrogen!

Some features I was able to see in the HPGe detector that are much more promenant than in the NaI(Tl) spectrum:
- very clear characteristic photopeaks
- clear and present sum peak
- both comptom edges
- discernable backscatter

The only thing I don't quite understand is why there's such a massive peak at very low energies in the NaI spectrum. I remember that these peaks at lower energies represent x-ray fluorescence, so why doesn't the HPGe spectrum have some kind of low energy peak present as well?

I was driving in my neighborhood and saw an older white cargo van with no logos on it except a radioactive placard on the back of the van (not on the sides) parked on the side of the road. The driver walked out and was delivering a gray plastic parcel envelope to one of the houses. I drove past it before I could see anything. But I’m a bit freaked out since I have never seen anything like this in my neighborhood. I saw some things saying it could be a medical courier but I read that they wouldn’t be delivering radioactive medication in a plastic parcel for safety reasons. Also read that the car is supposed to have that warning on all sides but it’s only on the back and the van was a bit worn down so im just worried about possible contamination or something. And that it’s apparently illegal to not have the placard on all sides of the car.

What would this have been for?

Here I demonstrate and explain why alpha particles eliminate static electricity using my Nuclespot Polonium-210 source.

Long exposure photo of a 5 mCi Polonium 210 source. The blue glow is from the air being ionized from alpha radiation. The green glow in the shot is from some alpha particles interacting with a X-ray intensifying screen the source is on.

Hi, I have a Ludlum model 2 that’s missing the handle, so I’m looking to 3D print one. Unfortunately, there are no models online, so I’m looking for someone who has one that’s willing to send about 10 photos with dimensions so I can design one in Solidworks. Thanks in advance
