Abstract

The concentration levels of natural radium isotopes such as 226Ra and 228Ra were measured in the atmospheric samples including rainwater, total suspended solids (TSSrw) and marine environment samples collected around the Kapar coal-fired power plant from September 2006 to February 2008. Activity concentration of 228Ra and 226Ra in rainwater showed the higher concentrations compared to the seawater. The mean activities of 226Ra and 228Ra in rainwater at Kapar were 20.45±4.50 mBq/L and 74.82±25.38 mBq/L, respectively. Meanwhile the levels in total suspended solids (TSSrw) of rainwater showed 226.99±52.57 Bq/kg for 226Ra and 439.92±186.17 Bq/kg for 228Ra. The measurements of radium isotopes concentration in rainwater at coal-fired power plant in Kapar are found in relation to their sources and application as tracers in lower atmosphere. The mean value of pH in rainwater during this study is pH 5.51 slightly acidic as lowest value for the standard of clean rainwater. Radium in seawater also strong adsorption onto total suspended solids with the distribution coefficient, Kd values of 228Ra and 226Ra ranged from 0.054 x 104 to 163.90 x 104 L/g and between 0.49 x 104 to 191.54 x 104 L/g, respectively.
