Lung Counter (in vivo contamination rapid screening system)

Product Description

The rapid screening system for HH-8008 internal pollution is an intelligent portable human body radiation dose detector. The instrument is composed of α and β radioactive contamination nasal swab detection system and γ radioactive contamination detection system in lung. The rapid detection of α and β energy spectrum through the wipe in human nostrils and the detection of γ-ray energy spectrum of radioactive substances inhaled into human lungs can realize the rapid measurement of the activity of radioactive substances contaminated in vivo for a large number of people. The instrument in the multi-channel spectrometer, total measurement, data acquisition and processing, method research and other technical aspects of the leading domestic level. The instrument uses rechargeable lithium battery power supply, small size, light weight, easy to carry, patented technology of digital data acquisition system to achieve the data of large capacity, high speed acquisition requirements. Single chip microcomputer control, with large notebook computer online use, Windows all Chinese operating system, so that the measurement is more intuitive, more convenient operation.
