Feature 1

Radiation Detector and Dosimeter

The counting rate of Radiacode under natural background is 300-500 CPM (Counts per Minute), which is, on average, 15-20 times higher than the rate observed with conventional dosimeters based on the Geiger-Müller tube.

The high efficiency of the 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.

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.

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.

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.

More Details

Given that combining precision and search capabilities without any loss is unfeasible, we've developed a device and application with two independent channels.

The first independent channel measures the dose rate accurately and quickly, functioning as a dosimeter.

The second independent channel measures the data registered by the detector without energy compensation.

Thus, the device also features a two-channel alert system.

Feature 2

Isotope Identification

Gamma spectrometry is a standout feature of Radiacode, making it a breakthrough in the realm of radiation detectors. Previously accessible only with costly laboratory equipment, this capability now fits into a pocket-sized device weighing just 67 grams.

Now, you can identify radiation sources, whether it's Radium-226, Cesium-137, Thorium-232, Am-241, or a number of other isotopes.

This is fascinating from a scientific perspective, as it immerses you in the mysterious world of nuclear physics and provides insight into the invisible matter around us. Study radiation sources, formulate hypotheses, engage in discussions within our communities of like-minded individuals, and make discoveries. It also has a vital practical applications.

From a safety standpoint, this is essential. If you detect isotopes like Radium-226, Cesium-137, or Americium in an urban environment, it's a reason to alert emergency services.

Furthermore, it holds significant importance if you happen to be in regions affected by the aftermath of the Chernobyl rains in 1986, as well as areas affected by nuclear tests and accidents. This impact extends to specific regions across Eastern, Western, and Northern Europe, the United States, Japan, Ukraine, Belarus, and Russia. The consumption of certain locally grown products from these lands could continue to pose health risks for the next 30 to 100 years, due to the presence of Cs-137 in these organic materials.

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 8.2% ±0.4% (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.

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 3

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.

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.

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.

Food Activity Monitoring

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

Cesium-137 is the most common nuclear isotope worldwide, settling across large areas of our planet after numerous nuclear tests in the USA and USSR, as well as several nuclear accidents, including Chernobyl. Winds and rains have carried Cesium-137 over vast distances, and traces of it can even be found in Africa and Antarctica.

The issue with Cesium-137 is that it's a synthetic isotope, never found in nature prior to its creation by humans. Living organisms mistake it for elements used in building organic tissues. Once it enters the human or animal body, it accumulates in the muscles, heart, and liver, where it can potentially remain throughout one's lifetime.

Unlike trace elements such as K, Ca, Zn, Fe, etc., which are beneficial to the body in small doses, Cesium-137 is harmful in any quantity.

Radiacode enables the measurement of the absolute and/or specific activity in various food products (expressed in Bq/kg) or provides results relative to maximum permissible concentrations (MPC).

With Radiacode, Cesium-137 can be detected in products such as berries, mushrooms, dairy products, domestic meat and game, honey, fish, and more. Ordinary dosimeters can only detect radiation in heavily contaminated products and cannot identify the presence of Cesium-137 as such.

Spectrogram Functionality

A spectrogram is a collection of gamma spectra recorded at specified time intervals, presented as a colored array capable of storing thousands of spectra. Don't worry, the recording is done automatically, continuously, and essentially without user involvement but can be extremely useful in various situations.

This mode assists in identifying the source of radiation if your alarm system suddenly starts and goes off, but you cannot immediately determine its cause.

As an example, it is quite possible to identify the radiation source as individuals who have undergone radioisotope therapy or contrast imaging pass by. Typically, these individuals trigger the alarm briefly as they pass, after which the background radiation levels quickly return to normal, leaving the user seriously concerned about the reasons for the device's activation.

In this case, the spectrogram operating in the background mode is likely to provide an explanation, having had time to record data about the event. By examining the recorded spectrogram at a convenient time, the user may discover that the source of the short-lived radiation spike was, for example, Technetium-99m.

Radiacode Sensor

The CsI (Tl) crystal, possessing optimal shape and size, in conjunction with the solid-state photomultiplier and specialized analog-digital processing, bestows the Radiacode dosimeter with high sensitivity across a broad spectrum of ionizing radiation energies, covering all directions from the device.

It's crucial to note that the Radiacode detector employs a cubic-shaped CsI (Tl) crystal, securing consistent sensitivity irrespective of the device's orientation towards the radiation source. This eradicates potential deviations in readings due to the position of the device relative to the radiation source.
