Abstract
The laboratory routinely operates two proportional counters; one 2-L (Dyck and Fyles, 1962) and one 5-L (Dyck et al. , 1965). CO 2 is used as the counting gas. The 2-L counter is operated mainly at 2 atm. and the 5-L counter mainly at 1 atm. On occasion the 2-L counter is operated at 1 atm. and the 5-L counter at 4 atm. No changes have been made in the CO 2 preparation and purification techniques described in previous GSC dating lists (Lowdon et al. , 1969; Lowdon and Blake, 1970).
