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.

Neutron penetration in water and through iron-water shields of practical interest obtained from P3 multigroup calculations employing P0-P3 scattering components has been reasonably reproduced by P3 11-group (10 nonthermal) calculations limited to P0 and P1 scattering components to which an extended transport approximation incorporating empirically determined cross-section adjustment factors is applied.
