Stone radioactive detectorIt is a professional equipment designed specifically for detecting the radioactive level of building stone. With core characteristics such as high detection sensitivity, accurate results, and convenient operation, it is widely used in stone mining, building materials market, decoration, quality supervision and other fields. It evaluates the radioactive nuclide content of marble, granite, porcelain tiles and other stones, provides key basis for the safe use and compliance judgment of building materials, and is an important equipment for ensuring the safety of living environment. ​

High sensitivity detection and precise quantification are its core competitiveness. The equipment is based on gamma ray energy spectrum analysis technology and uses high-resolution semiconductor detectors to accurately identify the characteristic gamma ray energy spectra of different radioactive nuclides. The detection limit can reach 0.01 Bq/kg, far below the national standard limit, and the measurement error is ≤± 5%. By processing the energy spectrum data with a multi-channel pulse amplitude analyzer, key indicators such as specific activity, internal irradiation index, and external irradiation index are automatically calculated to directly determine the safety levels of A, B, and C to which the stone belongs. In stone mining areas, the radioactive level of raw stones can be detected on site to screen mining sources that meet safety standards; In the building materials market, it is used for random inspection of stone materials entering the market to prevent stones with excessive radioactivity from entering the market. ​

Portable design and strong on-site adaptability. There are two types of devices: portable and desktop. Portable devices are powered by lithium batteries, with a battery life of up to 6-8 hours, suitable for rapid detection in mobile scenes such as mining areas and decoration sites; Desktop models are equipped with high-performance detectors and analysis systems, suitable for high-precision quantitative analysis in laboratories. The detection process does not require sample pre-treatment. The detector can be placed close to the surface of the stone to start the detection, and the single detection time can be adjusted from 5-30 minutes. At the decoration and renovation site, the supervisory personnel can carry portable detectors to detect the radioactivity of the paving stone in real time, ensuring the safety of the decoration materials; At the quality supervision department, a desktop detector is used to retest suspected stone materials that exceed the standard, and a testing report is issued. ​

Intelligent operation and data traceability are perfected. The stone radioactive detector is equipped with a touch screen operation interface and dedicated analysis software, with a built-in national standard limit database. After the detection is completed, a detection report is automatically generated, clearly indicating the stone grade and safety judgment results. Support data storage, export, and online upload, establish stone detection archives, and achieve full process radioactive safety traceability from mining to use. Some models are equipped with Bluetooth printing function, which allows on-site printing of inspection reports for easy supervision and verification. In real estate projects, batch testing of fine decoration stone materials is used to ensure the safety of homeowners' living; In stone export enterprises, product radioactivity is tested to meet the safety standards of the importing country and avoid trade risks. ​
