Cambridge University natural radiocarbon measurements V.

Abstract

The dates and activity measurements in this paper have been obtained during the year 1961, and have been made with CO (sub 2) at 3 atm pressure in a proportional gas counter as described in previous contributions from this laboratory. The assays were directed largely toward particular projects under investigation in the University Sub-department of Quaternary Research. In particular, concentration during 1961 was on the dating of sequences of samples from raised bogs where pollen-zone boundaries, stratigraphic horizons and the levels of important anthropogenic effects upon the countryside are all registered. The 30 samples described are from Great Britain with the exception of one each from Libya, Greece, and Israel.
