Plant uptake of radionuclides is one of many vectors for introduction of contaminants into the human food chain. Thus, it is critical to understand soil-plant relationships that control nuclide bioavailability. Our objectives in this study were to (i

Plant uptake of radionuclides into the human food chain is one of many vectors used for calculating exposure rates and performing risk assessment. This study provides a pedogenic assessment of soil-plant relationships in terms of their relationships

Radium is a potential Ca analog that may interact with Ca and Al in forest ecosystems. Many hectares of forested land in New England occur on soils with naturally high levels of radionuclides-including radium-but little is known about interactions of

Spodosols are notably difficult to classify in terms of moisture regime, presumably because redox colors are masked by spodic colors, or perhaps because the absence of structure in sandy Spodosols is a hindrance to detection of redox features. Some v

Elevated levels of naturally occurring radionuclides in bedrock of many areas of North America pose important issues for public health. Although soil surveys provide a great deal of information on many soil properties and interpretations, most do not

Pedologists and Quaternary scientists working with stratigraphic columns which may include paleosols have need of a simple, quantitative procedure to distinguish paleosols from unweathered sediments and to represent the degree of soil development. So

Increased pedologic interest in grus has created a need for better understanding of geologic and pedogenic processes producing such materials. Progress in this area is hindered by the incomplete understanding of pedogenic processes, as well as the fa
