Activity levels of po in the coastal area of Kapar, Malaysia, close to a coal-fired power plant
The activity concentration of 210Po from six different samples consisting of raw charcoal, surface sediment, rainwater (suspended solids (SSrw) and dissolved phase (Drw) and estuarine water (suspended solids (SSew) and dissolved phase (Dew)), were analyzed. The activity concentration of 210Po in s...

| Summary: | The activity concentration of 210Po from six different samples consisting of raw charcoal, surface sediment, rainwater
(suspended solids (SSrw) and dissolved phase (Drw) and estuarine water (suspended solids (SSew) and dissolved phase
(Dew)), were analyzed. The activity concentration of 210Po in solid samples was between 7.63 ± 0.67 and 744.28 ± 21.12
Bqkg-1 and in dissolved samples varied between 0.34 ± 0.03 and 86.33 ± 6.51 mBqL-1. On average, 210Po activity in
SSrw sample was the highest, at nearly three times its original form (charcoal). SSew and surface sediment samples were
similarly distributed between 15th March and 1st August samplings, but were relatively lower than charcoal and SSrw
samples. The natural meteorological variability also enhanced 210Po distribution and dispersion to a few kilometers
from the coal-fired power plant. |
