Does what it says.
Excellent. Instruction videos very good.

A real scientific instrument, not a toy
An incredible, real scientific instrument, not a toy. The model I have is the Radiacode 103. It is extremely sensitive; a granite headstone in a cemetery or war memorial monument will immediately show an increase in background as you get close. Natural background in a building from the stone, brick and plaster shows up quite clearly. It will even detect (though you need to sample for a few hours) the very low energy x rays emitted from a tritium keychain as the result of X ray fluorescence from the zinc sulphide phosphor. Smoke detectors and radium watches will drive it crazy with a red light and vibration warning (if enabled). It will show (again after a few hours of sampling) the peak from natural potassium 40 that is in food (and our bodies). It's a marvel of technology and if you have any interest in radiation, it's a terrific little gadget.

Radiacode
First impressions are that this is a very useful and versatile tool. Not used in a real situation yet but looks like its up to what it is designed for. Only mild constructive criticism - the menu that allows access to the different functions, I found a little awkward to access, plus no written instruction manual supplied, otherwise good value for money and i woul recommend.

Quality device superior to common GM counters
The ability to create spectrograms of unknown samples places this device at another level compared to simple Geiger-Muller tube devices. While small it is a sophisticated analysis instrument, but it is the software that makes it stand out. I'm using the Windows PC and also iOS app. The mobile phone app is just excellent for work in the field. I've knocked one star off because my example 103 is way out of calibration and I will need to re-calibrate it (fairly simple task requiring access to a standard such as Thorium 232, but the info on the Radiacode website is not a great deal of help).

Muy interesante como gadjet científico. No tengo idea de como funciona el modo espectrograma.

Fabulous device, even for casual hobbyists! Was able to measure radiation levels and review gamma spectrometry on several items. These included a "healing bracelet" I purchased at a rock and mineral show, two fossils and a uranium glass pitcher I picked up at an antique store. The bracelet and fossils were far more radioactive than I would have thought, so it was very useful in how I decided to store and display these items. It took a little while to figure out the gamma spectrometer function, but the manuals and app are easy to download, and the Bluetooth ios app readily connects when using an iPhone 15. Great value and lots of fun!! 5 Stars!!!

Für niedrige und mittlere Strahlungswerte besser als Geigerzähler! Kleine Geigerzähler sind normalerweise eher schlecht, weil sie durch das geringe Volumen des Detektors (GM-Zählrohr) und die geringe Dichte des Mediums (Gas) bei geringen Strahlungsintensitäten nur sehr geringe Zählraten liefern und damit nur sehr langsam auf Änderungen reagieren. Man muss dann viele Minuten oder Stunden messen, um brauchbare Messwerte zu erhalten. Der Radiacode 103 hat dieses Problem nicht, weil es ein Szintillations-Zähler ist und der dichte Detektor-Kristall selbst mit nur 1cm^3 Volumen schon ca. 6 CPS bei 0.07 uSv/h registriert (normale Hintergrundstrahlung hier). Außerdem kann es die Energie der Strahlung bestimmen und ein Spektrum erstellen, anhand dessen man dann bestimmen kann, was genau da strahlt. Das ist bei Geräten mit GM-Zählrohr so nicht möglich und andere Szintillations-Zähler sind eher teuer. Die (relativ jungen) Apps für macOS (Apple Silicon) und iPhone sind hübsch und funktionieren gut, die Android-App soll sogar noch etwas besser sein (diese ist schon länger verfügbar und daher ausgereifter und mehr verfeinert). Für Windows gibt es auch eine Software (habe ich nicht getestet) und es gibt eine FOSS Python-Library. Der Unterschied zwischen RC103 und RC102 ist die etwas bessere "Auflösung" der Spektren beim RC103. Kann man je nach aktuellem Preis und geplanter Anwendung dann entscheiden, was das bessere P/L-Verhältnis hat.

Appareil absolument génial utilisable seul ou en relation via Bluetooth avec le smartphone. Les applications sont complètes ! Toutes les variables sont personnalisables, les alertes, TOUT ! Je viens de faire un traçage de la radioactivité sur un trajet domicile, magasin d'alimentation de 5 km. L'échelle automatique, le panel de couleurs parfait. TOUT est précis, complet ! C'est absolument génial mais il est préférable de ne pas être novice en la matière... Mais pour un doctorant comme moi en science atomique depuis 30 ans, c'est génial. L'acquisition des doses est rapide !

Works as expected still need to dive into it to get to know the details of the apparatus
