DA-Ra02 Alpha Spectrum Radon Detector

DA-Ra02 Alpha Spectrum Radon Detector

Product introduction

DA-Ra02 α Spectrum Radon Detector is a radon testing device that do real-time and micro pump automatic continuous sampling of radon gas in air, soil and water. It uses a micro-pump combined with static electricity to collect radon decay. As the measurement object, daughter RaA meets the sampling and measurement method requirements of GB/T 14582-1993, and quantitatively measures the radon concentration in soil or air.

It has high sensitivity, easy operation, overcomes the inconvenience of manual sampling and external interference factors, and measures and gives results in real time. The measurement time can be set within 1-120 minutes according to the level of radon. It is the most automated instrument for soil radon detection in China. It meets the requirements of GB50325-2020 "Code for Indoor Environmental Pollution Control of Civil Construction Engineering" and soil radon measurement; /CECS 569-2019 "Standard for Radon Detection Method in Building Indoor Air".

It is widely used in civil construction engineering, radioactive ore prospecting emanation measurement and water radon concentration determination in hydration prospecting. It can also be used for radon level investigation and radon prevention and radon reduction in departments such as finding groundwater sources, earthquake forecasting, environmental protection engineering, scientific research and teaching, etc. and other research work. It meets the verification requirements of JJG825-2013 "Radon Meter".

Features

• Built-in measuring chamber with a volume of 0.8L

• It adopts the design of pump suction electrostatic collection energy spectrum analysis method, and at the same time uses the micro vacuum pump system to control the sampling flow to keep it at about 1L/min;

• Alpha energy spectrum has good resolution and high sensitivity, and the spectrum can be displayed in real time

• Desiccant is used at the sampling point to eliminate the influence of humidity on the measurement;

• The detector uses alpha particle semiconductor devices with high sensitivity, which can convert alpha particle rays into electronic signals, and measure the amplitude of electronic signals through electrostatic collection and amplification circuits, thereby identifying the energy of incident alpha particles;

• The instrument can accurately measure Po-218 particles produced by indoor radon decay, with good energy resolution and high detection efficiency.
