Abstract

The results of 210Pb, 210Bi and 210Po activity concentrations in the precipitation samples from the Kapar coastal area were presented and discussed in relation to their sources and application as tracers for the estimation of the residence time of particles in the lower atmosphere. It was concluded that the mean ratio was 0.53 for 210Bi/210Pb and 1.35 for 210Po/ 210Pb. Some results showed high activity ratios, 1.26 for 210Bi/210Pb and 6.33 for 210Po/ 210Pb, higher than the natural level, 1.0. These results may be due to additional 210Bi and 210Po excess. The presence of 210Pb, 210Bi and 210Po varied with time and this may be due to the variety of rainfall events and changes in aerosol content. Furthermore, the influence of dry deposition and wet deposition could be the major reasons as this particle reactive radionuclide tends to attach itself to aerosol particles. Thus the contribution from the factory may also be important as the amount of dust and coal burning will influence radionuclide activities. A comparison of mean radioisotope concentration profiles with a theoretical model indicates that the mean aerosol residence time in the atmosphere at the Kapar coastal area is 19 days from Pb-Bi derived calculations and 8 months from Pb-Po derived calculations.
