The water spinach (Ipomoea aquatica Forrsk.) is a common vegetable and a part of the staple diet in Vietnam. It has a well-known tendency for the high absorption of lead, including the radioactive isotope ²¹⁰Pb. ²¹⁰ Pb day to ²¹⁰Po, which is one of the most toxic radioactive isotopes when ingested. Currently, there are few data available on the activity concentration or transfer parameters of water spinach grown in Vietnam. To provide this data, in this study, the ²¹⁰Po activity concentrations in the soil, water and the roots, stems, and leaves of two types of spinach (grown in soil flooded with water and grown in normal soil) in Hanoi, Vietnam were determined by alpha spectrometry. The order of activity concentrations for water spinach grown in unflooded was C_stem < C_leaf < C_root, while for flooded C_stem ≈ C_root < C_leaf. The transfer factors followed a similar pattern.

菠菜（Ipomoea aquatica Forrsk。）是越南的一种常见蔬菜，也是主要饮食的一部分。具有铅的高吸收的众所周知的趋势，包括放射性同位素²¹⁰ Pb。 每天²¹⁰ Pb至²¹⁰ Po，这是摄入时毒性最高的放射性同位素之一。目前，关于越南种植的水菠菜的活性浓度或转移参数的数据很少。为了提供此数据，在本研究中，²¹⁰通过α光谱法测定了越南河内的两种类型的菠菜（在水淹没的土壤中生长并在正常土壤中生长）的土壤，水以及根，茎和叶中的Po活度浓度。放射性浓度的水菠菜被淹没生长的顺序为：C_干 <C_叶 <C_根，而对于淹没Ç_茎 ≈Ç_根 <C_叶。转移因子遵循相似的模式。
