Correlation between total suspended particles and natural radionuclide in Malaysia maritime air during haze event in June-July 2009

Atmospheric particles in the surface air including aerosol and dust were collected using high volume air sampler (HVAS) for obtaining the activity levels of 210Pb and 210Po over Malaysian waters during the EPSP’09 Scientific Expedition. The average mass concentration of total suspended particles (TS...
