Features

Feature 1
The Next-Generation Geiger Counter
Radiacode is a next-generation "Geiger counter" that radically changes the concept of nuclear radiation detection.
Enhanced Sensitivity and Efficiency
The counting rate of Radiacode under natural background is 300-500 CPM (Counts per Minute), which is, on average, 15-20 times higher than conventional Geiger counters . The high efficiency of the scintillation sensor allows it to acquire more data and respond to changes in real-time.
What advantages does this provide? Imagine finding yourself in an unfamiliar area and wanting to explore the territory for radiation. With a regular Geiger counter, you would need to move at a pace of 2-3 steps per minute. However, with Radiacode, you can walk at a normal speed and even record the radiation levels at each point. You could even record the radioactive path with GPS coordinates on Google Maps.
Reliable Performance in Varied Conditions
Each device undergoes temperature calibration ranging from +50 to -20 degrees Celsius, ensuring stable readings regardless of the temperature. Radiacode will provide accurate readings in any weather conditions.
Feature ImageFeature visualization overlay92Isotope LinkUUranium238
Comprehensive Measurement Features
Radiacode features Energy Compensation of the dose rate, allowing for equally precise measurement of both high-energy gamma radiation and low-energy X-rays. Measurement is conducted simultaneously in two channels : dose rate in microsieverts and impulses in CPS. In other words, one channel displays radiation intensity, while the other reflects the impact on living organisms.
Enhanced Safety with Customizable Alerts
Different isotopes and radiation sources affect organisms differently. Radiacode can recognize their energy and display accurate data regarding dose exposure. Importantly, for both CPS and μSv measurements, there is an alarm system that you can configure according to your preferences.

Advanced Food Contamination Check

Radiacode has a specialized mode for measuring the presence of Cesium-137 in food products.

Cesium-137 is one of the most widespread radioactive isotopes, released during nuclear tests and accidents in the 20th century, including Chernobyl. Winds and rains carried it across the globe — traces are even found in Africa and Antarctica.

The problem is that Cs-137 is an artificial element, previously unknown to nature. The body mistakes it for essential nutrients, causing it to accumulate in muscles, the heart, and the liver, where it can remain for a lifetime.

Meat

Mushrooms

Unlike minerals vital for health (potassium, calcium, zinc, iron), Cs-137 has no safe threshold — any amount is considered undesirable.

Radiacode uses technology similar to methods applied in food analysis labs, and can detect even trace amounts of Cs-137, estimate relative activity (e.g., in Bq/kg), and compare results with permissible safety limits.

This makes it possible to check foods — seafood, berries, mushrooms, dairy, meat, and more.

For food measurements, use a Marinelli beaker or other supported containers (sold separately, not included with the device).

Feature 3
Radiation Source Spectrum Visualization
Radiacode doesn’t just detect radiation — it visualizes the gamma spectrum, helping you recognize the type of source and letting you explore various nuclear isotopes such as Potassium-40, Thorium-232, Radium-226, Cesium-137, Uranium 238 and even the decay products of the radioactive gas Radon-222, like Lead-214 and Bismuth-214.
Gamma spectroscopy opens a window into the fascinating world of nuclear science — for hobbyists, students, educators, and curious minds alike.
It works almost like chemical analysis: the source emits gamma rays, and the Radiacode detector measures their energy and displays the spectrum. You don’t even need to touch the source. Just bring the device close to the object, and that’s enough.
Examine your surroundings, test rock samples, analyze antiques, study soil, share spectra in our online community — and make discoveries of your own.
And most importantly: no ordinary Geiger counter can do this.

Device Calibration and Spectral Accuracy
Every device has individual temperature calibration, ensuring consistent spectral recording even under significant temperature variations. The accuracy of the spectrum will be maintained regardless of temperature fluctuations. The spectrum resolution for Cs-137 is 8.4% ±0.3% (Radiacode 103) Full Width at Half Maximum (FWHM), considered the industry standards for scintillation spectroscopic equipment. For optimal visualization, you can view the spectrum chart on a Bluetooth-connected smartphone or PC.
Simplifying Spectrometry
You may have thought that spectrometry is complex and requires special skills. But it's actually quite simple. Just bring the device close to the object of study and restart the spectrum collection. Depending on the type of isotope and the source's strength, it may take anywhere from a few seconds to several hours.

Feature 4
Radiation Mapping
Radiacode's captivating feature is its ability to record radiation measurements on Google Maps or OpenStreetMap (OSM) when synchronized with a smartphone via Bluetooth.
Interactive Color-Coded Radiation Mapping
The device automatically captures radiation levels at user-defined intervals, creating a track composed of colored points on the map. The color of the track represents the radiation level at the corresponding location: shades of red signify higher levels, yellow indicates moderate levels, and blue and green show lower levels. This color-coding is as straightforward as a traffic light system.
Customizable Mapping and Sharing Features
Additionally, you have the option to customize your own color palettes. You can also export your maps to share with other Radiacode users or import their maps directly into your application.
Radiacode is your “sixth sense” in the world of radiation. You will discover places with elevated or reduced radiation levels, which may indicate interesting and unusual phenomena or objects.

Advanced Search Mode
This mode is specifically designed to help you detect radiation with maximum sensitivity, ensuring swift and efficient movement during critical operations.
  • With real-time updates, readings refresh twice per second, allowing you to cover larger areas in less time without compromising accuracy.
  • Enhanced audio feedback, available through your smartphone or headphones, keeps you informed in noisy or sensitive environments without drawing unwanted attention.
  • The analog indicator provides peripheral awareness, enabling you to monitor radiation levels without constantly checking the screen, making it easier to react in dynamic situations.
  • For those tracking radiation levels over time, the visual graph helps identify rising trends and allows for timely adjustments.
  • Additionally, the modified algorithm minimizes response delays, offering faster feedback for split-second decision-making.
Built on decades of experience with analog detection technologies and utilizing highly sensitive scintillator technology, this mode ensures the most responsive tool for radiation detection, helping you complete your mission quickly, safely, and accurately.

Spectrogram Functionality
The spectrogram feature continuously records gamma spectra over time and presents them in a compact, visual format for retrospective review.
This passive background mode allows the user to observe the evolution of gamma radiation patterns — without requiring active interaction or specialized knowledge.
In the event of a brief radiation spike, the recorded spectrogram may help the user understand when it occurred and examine the general spectral shape.
Feature ImageFeature visualization overlay55Isotope LinkCsCesium137
Real-Time Radiation Spectrum Visualization
In everyday environments, brief spikes in radiation levels can sometimes occur — for example, when individuals who have recently undergone radioisotope therapy or contrast imaging pass by. These short-lived events may momentarily trigger the device's alarm, often leaving the user puzzled or concerned.
However, with real-time gamma spectrum visualization running in the background, the device captures and stores spectral data during such events.
Later, by reviewing the recorded spectrogram, the user may observe distinct gamma lines that correspond to common medical isotopes, such as Technetium-99m, thus helping to better understand and contextualize the radiation spike — without guessing or alarm.
