Tupanex One is a wireless portable X-ray and gamma-ray spectrometer and dosimeter entirely developed in Brazil by Gaugit. The radiation detection market is characterized by a significant strategic gap: on one side are conventional Geiger–Müller (GM) detectors—affordable, but limited to simple dose quantification without spectrometry or radioisotope identification; on the other are high-cost professional spectrometers (US$3,850–20,000), typically restricted to laboratories and government security teams. Between these two extremes lies a vast market void—and that is precisely where Tupanex One is positioned.

The natural background radiation count rate measured by Tupanex One ranges from 6 to 8 CPS (counts per second), approximately 15 to 20 times higher than that of conventional Geiger counters. In field operations, this difference is transformative: with a Geiger counter, the operator must advance only 2 to 3 steps per minute to obtain reliable readings; with Tupanex One, the operator can walk at normal speed while recording radiation levels at every location along with GPS coordinates, generating real-time radioactivity maps integrated with GIS systems.

Tupanex One simultaneously measures two complementary parameters: count rate in CPS (counts per second), which reflects the intensity of the radiation field, and equivalent dose rate (µSv/h), which quantifies the biological impact. Automatic gain adjustment—performed by software through control of the SiPM bias voltage as a function of the temperature measured by the onboard sensor—preserves spectral-response linearity across the entire operating temperature range, a critical requirement for accurately identifying both high-energy gamma rays and low-energy X-rays. The complete gamma spectrum is displayed in real time, with radioisotope identification performed by onboard AI. The alarm system is independently configurable for both parameters: users can define separate thresholds for count rate (CPS) and dose rate (µSv/h), enabling distinct operational settings—for example, a source presence/proximity alarm (CPS) without triggering the biological exposure alarm (µSv/h).

In practical terms, Tupanex One delivers the core capabilities of portable gamma spectrometry—including radioisotope identification, count rate measurement, equivalent dose rate measurement, and spectral mapping—at a fraction of the cost of professional spectrometers. The difference is not limited to price: Tupanex One incorporates features that even equipment costing twice as much often lacks, such as onboard artificial intelligence, software-controlled bias voltage adjustment and other configurable parameters, as well as USB, Bluetooth, and Wi-Fi connectivity.

The name Tupanex One combines two elements with precise meaning. Tupã is the deity of thunder in Tupi-Guarani mythology—a symbol of strength, a high-energy natural phenomenon, and a direct reference to electromagnetic waves, the domain of the radiation detected by the product. Nex derives from the Latin nexus (connection, link) and the English word next (next generation).

The result is a brand name that conveys Brazilian identity, technological strength, and innovation—qualities that the product delivers in a genuine and verifiable way.
