摘要

在环境室内模拟了菠菜叶片在光照和黑暗条件下对氚化水（HTO）的吸收研究，并尝试使用IAEA TECDOC1616中的基本方程计算CTFWTHTO、CpfwHTO、CpcwOBT和CpfwOBT。将预测的活性与观察到的活性进行比较。在光照条件下，组织游离水氚（TFWT）向有机结合氚（OBT）的转化率更高。OBT与TFWT的比率在0.006到0.082之间变化。在光照和黑暗条件下观察到的OBT活性的比率（Bq/kg鲜重）在34%至117%之间变化。

Studies on foliar uptake of tritiated water on Spinach sp. during light and dark simulated conditions using environmental chamber

Studies on foliar uptake of tritiated water (HTO) on Spinach sp. during light and dark condition was simulated inside the environmental chamber, and an attempt was made to compute CTFWTHTO, CpfwHTO, CpcwOBT, CpfwOBT using basic equations available in IAEA TECDOC1616. The predicted activity was compared with the observed activity. The conversion of tissue-free water tritium (TFWT) to organically bound tritium (OBT) was more in the light condition. The ratio of OBT to TFWT varied from 0.006 to 0.082. The ratio of observed OBT activity (Bq/kg fresh weight) in light to dark conditions varied from 34% to 117%.
