“…before the beginning of tritium releases by the centre. This phenomenon is probably due to the first nuclear bomb tests performed at this time; it was already reported in the literature (Brown, 1979;Stark et al, 2005;Yamada et al, 2004).…”

“…OBT measurements in annual tree rings have been conducted to estimate the historical tritium levels in the environment (Brown, 1979;Stark et al, 2005;Yamada et al, 2004). Such analyses allowed a first investigation on tritium impact by the Valduc nuclear facilities on the nearby environment.…”

“…The cellulose fraction of 100 g corresponding to a single year was gently burned to obtain the combustion water for tritium measurement and CO 2 for 14 C measurement. 15,19 The carbon dioxide gas was collected as a dry-ice form, and the resulting dry-ice was immediately converted to calcium carbonate. Approximately 280 g of dried CaCO 3 obtained from 100 g of cellulose was stored in an airtight vessel.…”

Concentrations of organically-bound 14 C in the tree-ring cellulose of a Japanese Cedar (Cryptomeria japonica) grown in a rural region of Kanazawa, Ishikawa prefecture, Japan (36.5°N, 136.7°E), were measured for the ring-years from 1989 to 1998 to study relationship between 14 C concentrations in tree-ring cellulose and atmospheric CO 2 in a narrow region. An interesting result in comparing our data of tree-ring cellulose with those of atmospheric CO 2 is that the 14 C concentration in tree-ring cellulose was close to the corresponding average from mid-June to early September of 14 C concentrations in atmospheric CO 2. Furthermore, the 14 C concentrations in tree-ring cellulose were found to be merely influenced by the drastic decrease of 14 C concentrations in atmospheric CO 2 in winter, which might be caused by air pollution from the Asian continent and additional local fossil fuel contribution. These results suggest that the 14 C concentration in tree-ring cellulose for a given growing year reflects the 14 C concentrations of atmospheric CO 2 during the warm summer months.
