Radio analysis and its application in the Marine environment
Abstract
Similar With the Other environments in this Earth ? s spheres, the natural and artificial radionuclides are broadly Occurring in the Marine Environment. Since their^clock prop erties With different time scales , The radionuclides play a significant role in Study of
Marine environmental processes . However , The radio-analysis in , Marine system is quite different from Other environments. It ? More challenging for some factors , Like Time
Consuming field work, theeffectof salinity on proceduresof Enrichment and separation. moreover , The Short half-lives nuclides , such as 224 Ra and 222 Rn , can Be only measured by the The shipboard Instruments . After summarizing the radio-analysis Procedures such as the seawater Sampling ,radiochemical * Enrichment and Purificationmethods, Measurement techniques ,we Extended to Their applications in Oceanography study. Finally , Future
Development To the [] radio-analytical technique and its application in the Marine Environment were prospected .Keywords
