Smart Geiger Counter Radiacode-102 with Free Mobile App. Nuclear Radiation Detector.

This device is not just a geiger counter, it identifies any radioactive isotopes it come across. Absolutely marvelous and it creates exposure level maps along your travels. Battery lasts weeks and is fully rechargeable🔋

Excellent sensitive beta and gamma pocket scintillation meter. However, if you use it in microsieverts per hour mode (rather than counts/second), beware (1) it responds to beta radiation so you get a misleadingly HIGH indication of deep tissue dose in typical situations where both beta and gamma are present (it is not an "energy compensated" gamma dose rate meter, so the detector is not shielded to mimic the shielding of soft beta and low energy gammas by the skin), and (2) even for high energy pure gamma emitters, it indicates free-air dose rates which are typically 50% higher than the shielded deep tissue/bone marrow dose rates. In summary, you will tend to get over-estimates of your actual deep tissue gamma dose, unless you correct for shielding by soft tissue. (So either use it in counts/second mode, or multiply dose equivalent readings by 2/3 to get accurate deep tissue dose in ~1MeV gamma ray energy fields.) Apart from that, it is a lightweight, senstitive gamma detector and spectrometer. All software and instructions are online. To turn on, hold the round button down. To turn off, you need to press the round button once to bring up the menu on the right edge of the screen, then scross down using the "bar" scroll switch (located between the screen and round button), select the on/off symbol (a line in a partial circle), and then press the round button! The rechargable 3.7v lithium ion battery is apparently glued inside the case, so eventually you will need to break it open to replace the battery (or use it permanently on USB power from an external USB power supply).

Easy to use after the instructions have been followed. Multifaceted. Made with up-to-date technology. Very good value. Fast delivery.

Works perfectly

The Radiacode 102 stands as a remarkable achievement in engineering, showcasing state-of-the-art electronics and software clearly designed by a small team of passionate experts. Their dedication to creating the best possible product within budget constraints is evident, as is their enthusiasm, reflected in their active engagement with users on forums like Geigerzählerforum. This advanced yet user-friendly device revolutionizes the consumer market for radiation detection, making gamma spectroscopy accessible to a broad audience, including young physics enthusiasts. Its combination of affordability, performance, portability, and ease of use opens up fascinating opportunities to explore radioactivity using common sources such as thoriated gas lamp mantles, thoriated welding rods, uranium glass, and radioactive minerals like thorite and uraninite. The Radiacode 102 serves practical purposes too, quickly alerting users to increased gamma radiation levels during potential nuclear incidents, and capable of measuring weak radioactive contamination in environmental samples, though this requires extended measurement periods and lead shielding. As a scintillator detector, it not only measures radioactive radiation with high sensitivity but also identifies its origin, boasting approximately 7 times more sensitivity for gamma radiation than the Mazur PRM 9000 pancake Geiger counter and 20 times more than the GammaScout. However, it's less sensitive than Geiger counters for beta and especially alpha radiation detection. The device comes with versatile software options, including mobile apps for Android and iPhone, a Windows application (currently limited to USB connectivity), and compatibility with third-party software like BecqMoni for easy Bluetooth connectivity. It can also function independently, storing data in internal memory. In terms of performance, my unit achieves 9.8% resolution for Cs-137, sufficient for isotope identification, though it can't match the sensitivity and resolution of larger, more expensive scintillators. For highly sensitive measurements, such as detecting Cs-137 in food, I employ a NaI(Tl) detector with 50 times larger crystal from GammaSpectacular and a lead shield to suppress the background radiation. Overall, the Radiacode 102 represents a significant advancement in consumer-grade radiation detection technology, proving invaluable for both amateur enthusiasts and professionals in the field of radiation detection and analysis. I attach some spectra measured with the Radiacode-102 and the Android app: Radium 226, Thorium 232, Lutetium 176, Potassium 40, Cesium 137, Cobalt 60, Americium 241 and the beta emitter Strontium 90.

Following a minor issue with the item, the seller demonstrated exemplary commitment to resolving it with the level of professionalism and rigor one expects from a product of such inherent quality. The replacement unit was delivered in pristine condition, and the reverse logistics were handled with precision—using reusable packaging, clear documentation, and timely coordination. Communication remained consistently courteous, efficient, and solution-driven throughout. This experience reflects a supplier with operational maturity, technical accountability, and a genuine focus on customer assurance. Highly recommended for those who value excellence not only in instrumentation, but in the integrity of the service behind it.

Radiacode 102 -- he detectado K-40, Lu-176, y por supuesto, la aleación W-Th (WT-20) Excelente.

Considerando il costo, le dimensioni, la presenza di una app per pc mac android e iphone, l'autonomia, la sensibilità eccetera, è il top. Lo uso sia per registrare la radiazione di fondo nei miei viaggi (c'è una interfaccia con google maps? sì!) e nei punti salienti ci metto anche una foto (c'è anche quella possibilità), che come esposimetro quando lavoro in sala operatoria. La possibilità del collegamento via bluetooth col telefono o il pc e la presenza dell'app sono dei valori aggiunti incredibili rispetto ad altri geiger/dosimetri che avevo utilizzato. Recensione poco tecnica perché non sono un tecnico e ancora non sono riuscito a capire tutte le funzioni dello strumento, figuriamoci ad usarle integralmente e recensirle, ma mi sembra un bell'attrezzo. Raccomando moltissimo!!!

Amazing device, I don't know how I could live without it all my life. Besides count rates, dose rates, it measures energy spectra and provides alarms at user-set levels. I measured spectra from several natural, industrial and medical isotopes. It has a GPS function so it can make maps of radiation levels where I go. It's pretty fun to measure the dose rate when taking off, up in the air then landing. And to notice the differences when going nearer to the pole or nearer to the equator. Also the spectrum captures the 511 keV from the cosmic radiation positron annihilation. Very cool. Energy calibration from the factory was not perfect, but after some days of use I could set it myself (taking advantage of peaks like K-40).
