Study of soil-to-plant transfer factors (TFs) of Ra, Th, and K on plants cultivated on ex-tin mining land in Bangka Belitung, Indonesia.

Soil-to-plant transfer factors (TFs) are of fundamental importance in measuring the environmental impact due to the presence of radioactivity in soil and agricultural crops. The present study thus to measure soil-to-plant TFs of Ra, Th, and K on horticultural plants cultivated on ex-tin mining land in Bangka Belitung islands. There were 21 samples of 15 species and 13 families from 17 locations comprising four vegetables species, five fruits species, three staple foods species, and three others.

Heavy Metal Assessments of Soil Samples from a High Natural Background Radiation Area, Indonesia.

Mamuju, Indonesia, is an area with high natural background radiation. This study assesses heavy metal content in soil samples from this area to determine the level of public and environmental hazard it presents. This study analyzes natural radionuclide elements using high purity germanium (HPGe) gamma spectrometry and performs heavy metals analysis using a flame atomic absorption spectrometry (FAAS).

Comprehensive exposure assessments from the viewpoint of health in a unique high natural background radiation area, Mamuju, Indonesia.

Mamuju is one of the regions in Indonesia which retains natural conditions but has relatively high exposure to natural radiation. The goals of the present study were to characterize exposure of the entire Mamuju region as a high natural background radiation area (HNBRA) and to assess the existing exposure as a means for radiation protection of the public and the environment. A cross-sectional study method was used with cluster sampling areas by measuring all parameters that contribute to external and internal radiation exposures.

Radon Activity Concentrations in Natural Hot Spring Water: Dose Assessment and Health Perspective.

The world community has long used natural hot springs for tourist and medicinal purposes. In Indonesia, the province of West Java, which is naturally surrounded by volcanoes, is the main destination for hot spring tourism. This paper is the first report on radon measurements in tourism natural hot spring water in Indonesia as part of radiation protection for public health.
