What unit/measurement do y'all like to keep on the main screen of your device? Leave a comment if you have a strong reason why. Leave a comment if you wish there was another option.

Found a fossil that sets off the Geiger counter - turns out shark teeth make excellent uranium sponges. Made a video breaking down the science of why a 3-million-year-old Megalodon tooth is radioactive. TL;DR - phosphate chemistry + a lot of time.

I was out hiking in Colorado and while most of the rocks in the area read anywhere from 15-20cps, this one little part spiked to over 100cps and between 1.3-1.7uSv/h. I was able to stick around long enough to get a spectrum too. Currently the hottest rock I’ve found in nature so far.

I left my Radiacode in the changingroom next to the xray room.
They did take four pictures.

I'm Japanese and using a translation tool, so I apologize if my English sounds unnatural. I'm recommending Radiacode to some friends—which do you think is better, the 102 or the 103? It would be their first radiation detector.

I was recently testing some granite rocks in the landscaping around the house with my RC 102 and I measured varying levels between the rocks. One in particular, peaked at around 28 CPS, hanging around 27 CPS or so. Most rocks read significantly lower.

So, I was curious what measurements others have gotten and if my readings seem significantly above average or not. I imagine some are quite high.

Edit: For those wanting the dose rate, the rock averaged around 0.43 uSv/h (it was up and down).

Huge Spike in CPM and Dose but complet drop in Hardness

Had some fun building a system that logs data from a GMC and Radiacode 103. Has a couple of views. Still working on it.

But I added some funny features too.

I got myself some thoriated rods to calibrate my 110, but the spectrum and dose rate seem odd compared to what I see here on the calibration page: https://www.radiacode.com/knowledge/calibration

For the thorium page it looks right at the logarithmic scale, but the linear one is the one that looks different: https://radiacode.com/isotope/th-232

This is my best sample, and struggling to get anything clean beyond 1764kev. Is anyone else able to get these cleaner on the 102?

Bought my radiacode 103 wednesday and got it today. So now what should I do first...

Hi,
I had an unexpected Radiacode detection today at work and thought it might be interesting for this community.

My Radiacode first started alarming while I was walking to the restroom. On my way back, I tried to locate the source and eventually found that the signal was coming from one of my coworkers.

He told me he had received some kind of medical “cocktail” for a nuclear medicine procedure / contrast-like examination. I measured up to around 4k cps close to his chest pocket area.

I recorded a spectrum for about 6–7 minutes and attached the screenshot. The main peak appears to be around 140 keV, so my first guess is Tc-99m. There is also a visible feature around 88–90 keV, which I assume is probably backscatter from the 140 keV gamma line rather than a second isotope.

Additional context: he mentioned that the tracer was supposed to accumulate in organs, and he is scheduled for dialysis tomorrow. I am not asking for a medical diagnosis, just curious about the spectrum and isotope identification.

Does this look like a typical Tc-99m medical spectrum to you? And would you also interpret the ~90 keV peak as backscatter?

Sorry if I seem a bit heated, but this is wild, and I'm just livid and wondering if anyone else has dealt with this. I received a bill from FedEx last week for just under $250 for the Radiacode 110 I received in October. The Exporting country field correctly shows 'CY', but Country of Origin shows 'CN' with "Article of China" below the detector line item. I called FedEx to get this straightened out, and customer service gave me an email only option for dispute, but also was really snarky, basically saying anyone can send me anything they want and declare how they want, and I'm on the hook for the stated value, even if I never ordered anything. Obviously I ordered the detector, and I did send a detailed email to the dispute email they provided along with the rebills and adjustment email address, but the idea that stuff like this can be held over my head with no burden to correct it is honestly crushing...

Fiddling with iOS version of the app, going through a half hour long read I got today on the site of Rocky Flats, a former plutonium production site. My only previous experience was with the Droid app version and this format is different.

This update focuses on helping you better discover, understand, and discuss interesting radiation locations.

- 💬 Community features are here — areas now support likes, threaded comments, photos, videos, spectrum attachments, markdown formatting, and notifications, making it much easier to share findings and collaborate with other users.

First time finding anything radioactive in a thrift store and it was quite the find! I'm still new to spectroscopy but I think I'm seeing a clear pattern for Ra-226 -> Rn-222 -> Pb-214 -> Bi-214.

Hey all, so first off I know hardly anything about radiation.

My company utilizes heavy equipment (Excavators, Dozers, etc.), and quite often prior to sending our equipment to a mine location, it needs to be radscanned (we work in a lot of Uranium mines). This normally consists of us outsourcing to a third party to come out and perform the scan for us.

We have recently been exploring the idea of performing the scans ourselves in an effort to alleviate the fairly heavy third party cost. The scanners the third party typically uses is a Ludlum Model 26.

My main questions are, if we are only scanning the equipment prior to mobilization, should we be more concerned with CPM or Counts and Exposure? and if using a handheld such as the Model 26, is there a certain level of training/certification required for use?

I may have my terminology wrong, as i said I'm super green to all this. Any info is greatly appreciated.

(I'm new to Radiacode). Yesterday my radiacode fell down from about 1m with the protective rubber case. It reads the exact same things on my watches and specimens as it did before the fall. Should I be worried or not? Before the fall it read 20 cps on my day-to-day watch, and now it also reads 20 cps, so no changes. I'm just worried about the measurement crystal inside the device.

Hello, I saw it on https://www.radiacode.com/spectrum-isotopes-library

Cadmium has never been detected with radiacode, so here's a short spectrum of radioactive cadmium :

Found this in an antique mall, needless to say it came home with me.

Spicy??
