Going Nuclear: Notes from the officially unofficial book tour
I work in the analytical labs at one of Europe’s oldest and largest nuclear sites: Sellafield, in northwestern England. I spend my days at the fume hood front, pipette in one hand and radiation probe in the other (and dosimeter pinned to my chest, of course). Outside the lab, I have a second job: I moonlight as a writer and public speaker. My new popular science book—Going Nuclear: How the Atom Will Save the World—came out last summer, and it feels like my life has been running at full power ever since.

Atmospheric tritium concentrations and organically bonding tritium OBT of pine needles at NIFS Toki site had been measured considering environmental safety of future deuterium plasma experiment by large helical device (LHD). Atmospheric tritium concentrations of three chemical forms such as water HTO, hydrogen HT and methane CH3T had been measured since 2004. Tritium concentrations of HTO, HT and CH3T were distributed around 2-23 mBq/m3, 6-11 mBq/m3 and 0.5-3 mBq/m3 respectively. The HTO concentration principally depends on humidity in air. Recent decreasing rate of HT concentration to half was estimated 19.4 years. The OBT concentration tends to decrease and the rate to half was almost 9.4 years. Also the OBT measurements were cross checked with burning and liquid scintillation counting method and 3He mass spectrometric method. Both analyzed results showed good agreement. Long term monitoring of environmental tritium would be necessary from view point of safety on future nuclear fusion development.
