In this study, the activity range and distribution patterns of radium and radon isotopes in the coast sea of the Hongyanhe Nuclear Power Plant were investigated in autumn, 2017. The water ages were calculated by "Apparent Radium Age Model", which distribution was then used to assess the major direction of water transport in the study area. We also discussed the relationship between jellyfish abundance distribution and water transport direction. The results indicate that: (1) the activity ranges of 224Ra, 226Ra and 222Rn were 2.9−62.4 dpm/(100 L), 11.9−57.4 dpm/(100 L), and 0.1−1.3 dpm/L in the study area in autumn, respectively. (2) Based on the “Apparent Radium Age Model”, the so-calculated water ages were ranged from 0 to 16 d, with an average of (10.9±3.6) d. The major water transport direction was towards northeast with the velocity of 7.2 cm/s. (3) There was clear correlation between the distribution of jellyfish abundance and the major water transport direction. The higher jellyfish abundance was found in main water transport direction with older water ages.
