Measurement of tritium in tree rings: Relationship between tritium concentrations in pine tree rings and environmental samples

Organically bound tritium (OBT) for various plants in the vicinity of a continuous atmospheric tritium release

“…Lots of studies have been done on tritium incorporation into plants such as trees (Brown, 1979;Fuma and Inoue, 1995;Kalin et al, 1995;Kozak et al, 1993;Murphy and Corey, 1979;Stewart et al, 1972;Sweet and Murphy, 1984;Yamada et al, 1989), radishes (Choi et al, 2005), tomatoes (Spencer, 1984), and wheat (Diabaté and Strack, 1997). Nevertheless, some data are missing about the behaviour of tritium in the environment and the associated transfers.…”

Use of Tritium Accelerator Mass Spectrometry for Tree Ring Analysis

“…Therefore, tree rings appear to have the precision and sensitivity for use as passive monitors in tritium exposure reconstruction. More recently, studies have used trees to monitor anthropogenic sources of tritium in the environment ( − ). In the previous studies ( − ), sample sizes in excess of 10−100 g of woody tissues were needed for decay counting.…”

“…More recently, studies have used trees to monitor anthropogenic sources of tritium in the environment ( − ). In the previous studies ( − ), sample sizes in excess of 10−100 g of woody tissues were needed for decay counting. This required a prohibitive amount of effort in collection and preparation for analysis and destruction of old trees each time.…”
