University of Cambridge Natural Radiocarbon Measurements XI

Abstract
The measurements presented in this paper were carried out at the University Radiocarbon Dating Research Laboratory during the second half of 1971 using carbon dioxide counting. The counting equipment used was substantially that described by Switsur, Hall, and West (1970). Oxidation of samples of sufficiently high carbon content was performed in a stainless steel high pressure combustion bomb, developed at this laboratory, otherwise by ‘wet’ oxidation using acidified permanganate solutions for lake mud and samples of low organic content.
