A characteristic that allows for the separation and identification of closely spaced spectral lines or peaks.

This becomes particularly crucial when working with complex spectra where multiple components might overlap or exhibit similar energy values.

Dosimeter

The Radiacode dosimeter is designed for various tasks related to evaluating gamma radiation.

The dosimeter's sensitive component is a scintillation sensor comprising a high-quality cesium iodide crystal (CsI(Tl)) and a highly sensitive solid-state silicon photomultiplier (SIPM).

The Radiacode dosimeter employs special algorithms to process incoming data, enabling the dosimeter to quickly and efficiently register radiation spikes. It’s approximately 20 times faster than Geiger counter-based dosimeters. This high sensitivity allows for real-time tracking of even minor changes in the radiation background, which is essential for radiation level monitoring on the go. This capability is not provided by 99% of dosimetric equipment.

The Radiacode ensures high measurement accuracy through Software Energy Compensation. It calculates the dose rate from the radiation it receives. This ensures equally accurate measurements of both high-energy gamma radiation and low-energy X-rays. The device can measure multiple radiation sources simultaneously.

As energy compensation may yield low values for sources with low energy (since low energy results in a lower dose), readings without energy compensation can yield high values, which is vital for early hazard detection.

The Radiacode dosimeter is intended for assessing background radiation levels in the environment and measuring radiation levels from different substances and objects, including potential sources like building materials, antiques, vehicles, soil, etc.

The device houses a highly sensitive detector, detecting around 300-500 pulses per minute in natural background radiation. While this may be surprising to some, it simply reflects our existence in a high-energy flux, accurately portrayed by the efficient sensor.

Each device is calibrated during production using certified radiation sources, with individual calibration recorded in the device's non-volatile memory.

Additionally, every device undergoes temperature calibration from +50 to -20 degrees Celsius to establish its characteristics at different temperatures, eliminating temperature influence when acquiring a spectrum and measuring radiation.

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 #1

Radiation Detector and Dosimeter

Counts per Minute (CPM) is the most important characteristic of a radiation detector, as it determines its operational speed.

The counting rate of Radiacode is 300-500 CPM, which is on average 15-20 times faster than conventional dosimeters based on the Geiger-Müller tube.

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.

Spectrometer and 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 9-10% Full Width at Half Maximum (FWHM), comparable to high-end laboratory 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.

Feature #4

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.

Chernobyl rain fallout spots

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.

Intelligent Features

The intelligent features of device encompass various solutions to enhance the efficiency of different device operations.

Controls icon

Device Calibration

A significant challenge with scintillation devices is temperature variation, which can cause a noticeable shift in the spectrum to the point where isotopes cannot be accurately identified. To counter this, we calibrate each device on the production line to accommodate for temperature. Consequently, temperature fluctuations no longer influence the spectrum or the readings. Radiacode is calibrated during production using reference radiation sources to ensure the maximum accuracy of the spectrometer. Furthermore, we provide the option for self-calibration, allowing users to calibrate the device themselves.

World icon

Mapping the Terrain

Charting the hazardous terrain and incorporating data into a map track is a complicated task. At high speeds or when there are minor increases in background levels, the device might need additional time to reflect changes, leading to track discrepancies. To tackle this, we have developed speed compensation during track construction, considering the time necessary for computations. Consequently, the track no longer lags and accurately exhibits areas with elevated background levels.

Update icon

Safe Update

Considering the anticipated frequency of software updates for the device, we have incorporated safeguards against firmware glitches. This ensures that even in the event of firmware corruption, the device won't require shipment for repairs. In the occurrence of any errors, the device is always ready for reflash. Firmware updates can be carried out wirelessly on the device, but it is also possible to execute a wired firmware update using a PC or Android device.

Rout icon

Track Refinement

In the process of building the track, we initially capture standard data, which we subsequently replace with more precise information, considering measurements obtained slightly later. This methodology limits the dispersion of readings along the track, enhancing its interpretability. To further refine the display of the track and decrease the computational load, we provide an option to prune the track by removing redundant markers on the screen.

Dual channel icon

Dual-Channel Architecture

To seamlessly merge precision with search capabilities, we've engineered a dual-channel architecture for the device and its associated applications.

The first autonomous channel swiftly and accurately gauges the dose rate, functioning as a dosimeter.

The second autonomous channel captures signals detected by the detector, excluding energy compensation.

Card icon

Autonomous Device

We have engineered the device to be fully autonomous, featuring approximately 32 megabytes of built-in memory. This is enough to store data for roughly a month without requiring a connection to a smartphone.

Warning icon

Dual-Channel Warning System

The compensation method may deliver lower readings for low-energy sources (as lower energy correlates with a lower dosage), and readings without compensation might present higher values.

These higher readings are vital for early hazard identification. Hence, the device is equipped with a dual-channel warning system.

The Radiacode 102 dosimeter is showcased in an ergonomically designed plastic casing, making it convenient and comfortable to use.

The device is equipped with a clear, monochrome graphical display and it incorporates auditory, visual, and tactile alerts, providing a variety of notification options.

This dosimeter comes with an automatic screen backlight feature for optimal visibility in low-light conditions, and it offers high-contrast settings for superior readability in bright environments. In addition, the screen rotation can be manually set according to the user's preference for either left or right-hand operation. Alternatively, the device is capable of automatically adjusting the screen orientation using its in-built accelerometer.

More Details

This ensures convenient and adaptable use of the dosimeter in a variety of lighting conditions and allows users to customize their preferred screen orientation for optimal usability.

Furthermore, the dosimeter offers long-term autonomy, capable of up to 200 hours of active operation. It can be easily recharged, akin to a cellphone, ensuring continuous use without the need for frequent battery replacements.

In conclusion, the ergonomic design, adaptable display settings, and extended battery life of the Radiacode 102 dosimeter contribute to a user-friendly experience and dependable radiation monitoring capabilities.

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 102 dosimeter 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.
