| Summary: | Natural radioactivity measurements in soil, sand, and water samples obtained
from Northern Peninsular Malaysia (NPM), comprising the states of Penang, Kedah,
Perlis, and Perak were carried out using the Exploranium GR-135 Plus, High Purity
Germanium (HPGe), and NaI (Tl) spectroscopes. The activity concentrations of 238U,
232Th, and 40K in Penang, Perlis, Kedah, and Perak states were found to be within
those reported from literatures for other countries of the world. All the health hazard
indices are well below their recommended value, except some soil from Kedah and
Perak states. Soils with Hin and Hex< 1 are suitable for agriculture and as building
materials. Also, in this study Hin and Hex< 1 for water, therefore, water after
processing and filtration is safe and suitable for use in household and industrial
purposes. The sites of high concentrations of displaying 226Ra/238U disequilibrium. |
