Description 376-383
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.
