The radioactivity concentration of environmental radionuclides was analyzed for soil and
sand at eight locations within a radius of 255 m centered on the Dongnam Institute of …

Natural and fallout radioactivity were estimated in topsoil samples collected in eastern
region of Shangrao Prefecture, China. The average activity concentrations of 238 U, 226 Ra …

In this study, we investigated the activity concentrations of natural (226 Ra, 232 Th, 40 K)
and artificial (137 Cs) radionuclides of soils in Jeju Island, and radiation hazard indices …

This paper presents the evaluation of natural radioactivity and radiological hazards of the
terrestrial naturally occurring radionuclides of^ 226 Ra 226 Ra,^ 232 Th 232 Th and^ 40 K …

The present study aims to obtain the baseline data on natural and fallout radioactivity and to
evaluate radiation hazards caused by ionizing radiation emitted from 226 Ra, 232 Th, 222 …

The concentrations of natural and artificial radionuclides in soil and gamma ray dose rate in
air at 233 locations in Korea have been determined. The national mean concentrations of …

We investigated the amounts of radiation exposure from $^{238} U $, $^{232} Th $, and
$^{40} K $ which are three major radionuclides naturally residing in soil of the Korean …

The concentrations and activity ratios of 90Sr, 137Cs, 239+ 240Pu and 238Pu in surface
soils (0–5cm) of Korea were determined. The concentrations were in the range of 1· 10–13 …

The activity and gamma-absorbed dose rate due to the naturally occurring radionuclides in
the terrestrial environment such as 238U, 232Th and 40K were determined in soil and rock …

Specific activities of 134 Cs and 137 Cs in surface soil and moss samples were investigated
at 12 locations of Jeju Island, Korea. Specific activities of 134 Cs and 137 Cs in the surface …
