Introduction to alpha spectrum radon measuring instrument:

Alpha spectrum radon measuring instrumentIt is a measurement instrument for radon concentration in environmental air, soil, water, and radon release rate in soil, building materials, etc. It can be used for geological exploration, radiation protection, nuclear accident monitoring, radiation dose evaluation, earthquake prediction, and teaching.
Alpha spectrum radon measuring instrumentThe standards/regulations that comply are GB 50325-2020 "Standard for Indoor Environmental Pollution Control of Civil Building Engineering", GB/T 14582-93 "Standard Measurement Method for Radon in Environmental Air", and T/CECS 569-2019 "Standard for Radon Detection Method in Indoor Air of Buildings".

Instrument features:

• Detector: passivated ion implanted planar silicon (PIPS), with extremely thin contact, sturdy, and low noise;
• Pump suction electrostatic collection energy spectrum analysis method;
• The alpha energy spectrum has good resolution, high sensitivity, and real-time display of spectra;
• Fast measurement response and short recovery time;
• Constant current sampling, gas volume samplinggood；
• Small size, light weight, easy to carry;
• Low power consumption, dual-use for both AC and DC;
• USB data transfer interface, Bluetooth printing of measurement data.
