Engineered to Measure Radiation the Way the Human Body Experiences It

At the heart of Radiacode Zero is an organic tissue-equivalent scintillator made from EPS100 polystyrene—a material that responds to gamma radiation much more like human soft tissue.

A conventional Geiger counter is different. Its detector is typically made of glass, steel, and gas—materials very different from human tissue. As a result, it can only approximate what different radiation energies mean for the human body, relying on broad averaging and carrying significant limitations.

Think of gamma rays as countless tiny bullets of different calibers and energies. Some carry a little energy. Others carry a lot. And that difference matters.

Imagine trying to understand what those bullets could do to a person. With Radiacode Zero, it's more like firing them into a tissue-equivalent ballistic mannequin while also knowing the energy of every shot. You get a much clearer picture of what you're dealing with.

A conventional Geiger counter is more like firing those same bullets into a steel plate and judging their effect on a human body from the dents alone—without knowing the caliber and how much energy each bullet carried.

Radiacode Zero doesn't just detect gamma radiation. It doesn't just tell you radiation is there. It is engineered to measure it in a way that more closely reflects how gamma radiation interacts with the human body.

Penetrating Radiation Is Far More Diverse Than Most People Imagine

Many people picture radiation as identical particles passing through space. Conventional Geiger counters work in much the same way—they primarily count detection events without measuring the energy of each interaction.

In reality, gamma rays come in a wide range of energies, and that difference matters. Lower-energy particles are more easily absorbed by air and the outer layers of the body, while higher-energy gamma rays can penetrate much deeper, reaching internal tissues and organs and contributing differently to radiation dose.

A conventional Geiger counter cannot distinguish between these energies. A low-energy photon and a high-energy photon may produce the same count, even though their contribution to dose can be very different.

Radiacode Zero measures the energy of various gamma interaction and uses this information to estimate the ambient dose equivalent rate H(10)—the internationally accepted quantity used to assess the potential impact of external gamma radiation on the human body.

Instead of simply counting radiation, Zero provides a more meaningful answer to the question that matters:

What does this radiation mean in terms of dose to the human body?

Stays reliable when others overrange

Most consumer Geiger counters have an upper measurement limit of around 1 mSv/h. Under normal everyday conditions, radiation levels this high are rarely encountered.

However, during a severe industrial accident or nuclear emergency, radiation levels in the first few days following such an event can rise hundreds or even thousands of times higher—even at considerable distances from the source.

When this happens, most consumer radiation meters reach their measurement limit, enter an overrange condition, and stop providing meaningful information.

Radiacode Zero continues measuring radiation levels up to 9 Sv/h (9,000 mSv/h)—a measurement range 9,000 times wider than that of a typical consumer Geiger counter.

*up to x9,000 wider than a typical consumer dosimeter’s dose-rate range (based on common upper limits around ~1 mSv/h). Actual performance depends on device type, settings, and conditions.

Instead of going blind when radiation information matters most, Radiacode Zero continues to provide reliable measurements to help you understand what's happening around you and make informed decisions.

Combined with its energy-compensated dose assessment, Zero also provides a more realistic estimate of accumulated dose—replacing guesswork with objective data and helping reduce uncertainty, psychological stress, and panic during a radiation emergency.

Designed for Everyday Discovery. Ready for the Worst Day

Under normal conditions, Radiacode Zero is a modern personal radiation detector designed for everyday use. Whether you're checking suspicious objects, exploring abandoned places, monitoring your surroundings, or simply satisfying your curiosity, its highly efficient scintillation detector delivers a count rate up to 10 times higher than conventional Geiger counters, helping you detect changes in radiation levels much faster.

Powered by an advanced plastic scintillator, a solid-state photomultiplier (SiPM), and a high-performance ARM Cortex-M4F processor, Radiacode Zero combines high sensitivity with stable, reliable measurements.

It weighs just 76 g, fits comfortably in your pocket, and delivers up to 200 hours of battery life on a single charge—making it easy to keep with you every day.

Hopefully, you'll never need its full capabilities. But if the unthinkable ever happens, Radiacode Zero will continue delivering meaningful radiation measurements long after conventional Geiger counters have reached their limits.

Safety Compass

In the early phase of a large-scale radiological incident, radiation levels in the environment can rise to extremely high values and present serious health and life risks.

Civil defense guidance highlights the importance of effective shielding during radiological emergencies. Proper sheltering can further significantly reduce radiation exposure. Spending the first days in shelter is essential to minimize accumulated dose.

However, even inside a shelter, radiation levels can vary significantly during the initial period

Radiacode Zero provides real-time radiation data that can help to:

spot the safest locations within a shelter;
detect weak points and leaks in shielding or sealing, and undertake possible actions.

By converting invisible radiation into clear, quantitative information, Radiacode Zero supports informed, responsible decision-making focused on personal safety in emergency situations.

Fire Extinguisher for Radiation Emergencies

You may never need it.

But if you do, it can help protect health and reduce risk when conditions become severe.

It is better to have a tool that works as a normal everyday device under routine conditions and continues to deliver reliable information when conditions become extreme, than to rely on a standard detector that goes blind precisely when accurate data becomes critical.

Frequently asked questions

Radiacode Zero uses a plastic scintillation detector combined with a semiconductor photomultiplier, allowing the device to accurately measure both low background radiation levels and extremely high radiation fields. Most consumer Geiger counters on the market are based on Geiger–Müller tubes designed for low radiation levels, typically with an upper measurement limit of around 1 mSv/h, with less common models reaching up to 10–20 mSv/h. Once this upper limit is reached, such devices effectively stop providing meaningful measurements and become “blind” precisely when radiation information becomes critical. Radiacode Zero can measure radiation levels up to 9 Sv/h (9000 mSv/h), which is significantly higher than most consumer Geiger counters that typically max out at 1-10 mSv/h.
