Determination of elements due to atmospheric deposition on Barbula indica Moss at Dalat, Vietnam using NAA and TXRF techniques

In this paper, two multielement analysis techniques, Neutron Activation Analysis (NAA) and Total Reflection X-ray Fluorescence (TXRF), are combined to detect elemental concentrations in Barbula indica moss collected at Dalat, Vietnam. Combining these two techniques has improved the qualitative det...
