In topsoils, the activity concentrations of natural radionuclides (hereafter NRs) increase due
to the addition of NRs from fertilizers, irrigation water, and air dust pollution. On the other …

Groundwater and inorganic fertilizers are regularly applied to agricultural soils, but their 226
Ra content is potentially hazardous to human health and the environment. Due to irrigation …

Groundwater is a major source of drinking water and agricultural water in some regions of
the world. However, it contains a high level of 226 Ra that is potentially hazardous to human …

In the world, many studies have focused on the natural radioactivity in agricultural soils and
food crops and the transfers of radionuclides between two components. However, the …

The effects of fertilizers, irrigation water, and air dust pollution on the long-term accumulation
of radionuclides in surface soils have been investigated worldwide. In addition, many factors …

Solid-liquid partition coefficients (K d) of Ra-226 and Po-210 were measured for five
agricultural soils in five fields in the south of Vietnam. Rice, maize, water spinach and tomato …

The mitigation rate (R j) was evaluated for Ra-226 in cultivated soil in twelve fields in
Vietnam. For the collected soils, the R j values were between 0.1 and 0.58 Bq kg− 2 y− 1 …

In this work, activity concentrations of 226Ra, 232Th, 40K and 137Cs in soil and plant
samples in Vi Thanh City were analyzed by laboratory gamma spectrometer with HPGe …

[en] The leaching process of radionuclides into the deep soil or groundwater is the main
