DHZM-II Radon and daughter measuring instrument

Radon and daughter measuring instrumentFor portable "integrated", "real-time", and "continuous" measurement of radon concentration/radon progeny/total∂The multifunctional instrument for potential concentration can be used for measuring radon in underground engineering, underground mines, tourist caves, nuclear facilities, associated uranium deposits, and indoor environments. It is an essential device for finding sources of radon (thorium) and complies with the occupational health and safety assessment of radon progeny monitoring and radon dose estimation by the International Commission on Radiological Effectspricerequirement. This instrument is suitable for large-scale radon level surveys; It can also be used for online monitoring of uranium radium mines and underground engineering, achieving interlocking control with radon prevention, radon reduction, and radon ventilation systems.

lDetector: Semiconductor detector, fast response, insensitive to gamma radiation

lSensitivity: 1.2 × 10^-3cps/Bq/m³(Radon), counting capacity 99999999; Measurement range: Radon/radon progeny concentration 3-10⁶Bq/m³，∂Potential concentration: 1 × 10^-8-10^-2J/m³

lMeasurement time interval:Method 1(Radon concentration measurement),Mode 3The measurement of both offspring and potential took 26 minutes, which means the results were obtained after 26 minutes;Method 2Set a time within 1-120 minutes based on the level of radon
