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

Abstract

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%.
