The village of Vinaninkarena, Antsirabe, Madagascar (47 degrees 02'40''E, 19 degrees 57'17''S) is located in a high natural radioactivity area. In order to evaluate the natural radionuclide content in soil, sampling was done on-site by the transect method (85 soil samples) and off-site through transects across and beyond the region (up to a range of 100 km), to determine the natural radioactivity variation within vs. outside the region, and to detect significant differences, taking into account spatial variability.
马达加斯加安齐拉贝市的维纳宁卡雷纳村（东经47°02′40″，南纬19°57′17″）位于高天然放射性区域。为评估土壤中的天然放射性核素含量，采用样带法在现场采集了85份土壤样本，并在区域内外通过样带进行了场外采样（范围达100公里），以确定区域内与区域外的天然放射性变化情况，并考虑空间变异性来检测显著差异。
