| 英文摘要 | The Jiangmen Underground Neutrino Observatory is proposed to determine neutrino mass hierarchy using a 20 ktonne liquid scintillator detector. Strict radio-purity requirements have been put forward for all the components of the detector. According to the MC simulation results, the radon dissolved in the water Cherenkov detector should be below 200 mBq/m(3). Radium, the progenitor of radon, should also be taken seriously into account. In order to measure the radium concentration in water, a radium measurement system, which consists of a radium extraction system, a radon emanation chamber and a radon concentration measurement system, has been developed. In this paper, the updated radon concentration in gas measurement system with a one-day-measurement sensitivity of similar to 5 mBq/m(3), the detail of the development of the radium concentration in water measurement system with a sensitivity of similar to 23 mBq/m(3) as well as the measurement results of Daya Bay water samples will be presented. |
