R. Eisma et al., MEASUREMENTS OF THE C-14 CONTENT OF ATMOSPHERIC METHANE IN THE NETHERLANDS TO DETERMINE THE REGIONAL EMISSIONS OF (CH4)-C-14, Nuclear instruments & methods in physics research. Section B, Beam interactions with materials and atoms, 92(1-4), 1994, pp. 410-412
We give a brief description of a method to determine the (CH4)-C-14 em
issions in NW Europe. We report the first measurements of atmospheric
(CH4)-C-14 in The Netherlands, ranging from 124 3 to 426.5 pM. Prelimi
nary analysis suggests a contribution of (CH4)-C-14 from nuclear insta
llations other than pressurised/boiling water reactors.
