A study on seasonal variations of Po-210 levels in a coal burning power station area of Malaysia

Research output: Contribution to journalArticle

Abstract

In order to evaluate the possible radiological impact to the environment from a coal burning power plant, Po-210 concentrations in water, suspended matter (TSS), and surface sediment samples collected from the Kapar coastal area, is investigated. Results show that the mean Po-210 concentrations are 0.69±0.34 mBql-1, 85.90±65.62 Bqkg-1 and 33.19±14.85 Bqkg-1 in water, TSS and sediment, respectively. About 99% of them are associated with the particulate phase of water. Comparatively, higher Po-210 values have been observed when compared to the values shown in literature, which is suspected to be the impact of coal burning. The calculated values of Kd range from 9×105 to 381.1×105 Lg-1 and show a negative log Kd versus the TSS correlation. An attempt has been made to investigate the seasonal variation pattern of Po-210 accumulation in the marine environment and a clear relationship is revealed with higher Po-210 concentration during the northeast monsoon period.
