r/Radiacode

Hey everyone!
Just printed a brand-new protective case for my Radiacode in bright high-vis yellow. I wanted something highly visible so I don't accidentally leave it behind on a rock during field prospecting, plus a sturdy loop for a lanyard.
Took it out for a quick test run in the woods to check out some local granite boulders:
Background / Lower activity rocks: ~8.1 to 9.5 CPS
Higher activity granite: Jumped up to 18.7 CPS on a particularly spicy rock!
The neon yellow color contrast makes it super easy to spot against moss and soil, and the snug fit protects the device without blocking the screen or controls.
What do you think of high-vis cases for field work? Do you prefer a subtle black TPU or high-contrast colors when prospecting in the woods?

Visited South Terras Mine today, but only stayed in the vicinity and didn't enter the private property. Still very high readings and the alarm went off already in the car 300m away. The dip in the measurement results from a detour to a neighboring field to get a different view. Was really surprised about the radiation levels - over 500 mySv/h without even being close to the mine! The spectrum indicates Bi 214 as part of the Radium chain

Got a Radiacode 110 today as a birthday gift. I love it. I cant wait to see what all this will show me about the world around me😁

A very interesting read!

Was just walking to the local shop when my Radiacode started throwing high-dose rate alarms out of nowhere.
Looked around and noticed a trench in the street with pipe replacement work going on. Turned out the NDT crew was performing gamma radiography on the pipe welds using a gammagraphy camera (Sentinel 880 / Ir-192).
Walked over, had a brief chat with the operator (he was definitely surprised to see a civilian with a scintillation spectrometer tracking his source on a live waterfall graph!), got a quick measurement, and went on my way.
Peak dose rate: 450 uSv/h (when the source was briefly exposed/actuated)
Count rate: 1.4 kCPS nearby
Spectrum: Beautiful Bremsstrahlung curve from the depleted uranium shielding / soft scatter + hard Ir-192 gammas.
Definitely the coolest random sidewalk find I’ve had so far!

I brought my Radiacode 110 with me on a dolphin-watching boat trip during our vacation in Croatia, mainly because I was curious how much the gamma background would drop once we were well away from land.

I let it accumulate a spectrum for 2 h 40 min, and the average count rate was only 1.52 cps.

The first image shows the spectrum measured on the boat. In the second image I overlaid it with a spectrum measured in my garden at home for comparison.

The difference is quite dramatic. At sea, most of the terrestrial gamma contribution from soil, rocks and buildings is essentially gone, while the large volume of seawater provides additional shielding from radiation originating below and around the detector. What remains should therefore be dominated much more by cosmic radiation, secondary radiation and whatever small contribution comes from the boat itself.

The comparison is especially interesting because the Radiacode 110 normally sees a much higher background on land. The reduction of the low-energy continuum is very obvious in the overlay.
Not exactly the usual thing people take on a dolphin-watching cruise, but this is probably one of the more interesting background measurements I’ve made with the RC110 so far. 😄

Has anyone here done longer open-sea measurements with a Radiacode? I’d be interested to see how your spectra and count rates compare.

This is a nearly 4 day spectrum on glass subject suspected to contain uranium.

Is this sufficient enough for a positive ID, or do I need some shielding to get better results?

Radiacode 102

Does anyone know if Radiacode would refurbish my 103G that I ran through the laundry? Forgot it in my pocket and I’m devastated.

I have an issue with my Radiacode. My phone signal is setting off the Radiacode from a fair distance away. In the first photo, I have the detector directly next to my phone, and the frequency of it being set off is definitely higher. The issue is with the other detections. I have my phone in my opposite pocket, and it seems to be setting it off at random. Sometimes my RC is on the desk at a minimum of 2 feet away and still getting set off. Is anyone else having this issue at this level?

So after a year I remembered the compass I have again, I already posted this topic once, but I didn't add a video and probably because of that it wasn't so clear what this compass could contain, thanks for the help.

I was on the Dump of an old uranium mine in the Black Forrest
