摘      要：Radon is recognized as a powerful tracer of certain geophysical processes in marine and aquatic *** the past few decades,the instruments and methods for measuring radon concentration in water have been developed to some extent but still lack underwater in-situ *** we present an in-situ detection equipment for radon-in-water(pulsed ionization chamber(PIC)-radon)to measure dissolved radon in ocean and groundwater *** equipment has been successfully deployed in the Jiaozhou Bay in July 2022 and has achieved 14 d of unattended underwater in-situ *** it was successfully placed in a groundwater monitoring well in the Laizhou Bay in November 2022 and monitored radon activities for over 30 *** results showed that this instrument had a good indication of submarine groundwater *** PIC-radon detector takes advantage of smaller size,lower power consumption,and is barely influenced by humidity,making it particularly suitable for long-term in-situ measurement,especially in harsh environments with limited human care or deployment spaces.
