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

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 4****k 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?

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.

First time using my radiacode and for my birthday tomorrow we decided to explore the most radioactive point in the UK!

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.

- 🗂 Area categories help surface interesting places and improve exploration. Existing areas were categorized automatically; if you notice an incorrect category, you can submit an edit.

- ✨ Area pages have been completely redesigned on desktop and mobile, with a new media gallery, improved information layout, better sharing previews, and easier access to spectra and supporting materials.

- ☢️ We've also added a new Radiation Context section to help answer the common question: "What am I looking at?"

- 🔒 Finally, this release introduces several new privacy and data protection features, including anonymous track publishing, self-service data export and account deletion, a 24-hour delay for newly recorded track points, and updated retention policies for inactive accounts.

- Thank you for helping build the world's largest community radiation map.

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.

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 :
