Extract
Radiocarbon, Ltd. is a privately owned laboratory designed to provide quality service to the archaeologic and geologic communities. Operations began in 1969 using standard techniques for preparation, conversion to CO2, and purification of samples prior to counting. A sample is counted as CO2 in each of two identical proportional counters of volume 2.2 L, built on the design of östlund and Engstrand (1963); each counter has its own multi-anode guard ring, and is housed in a common shield of iron 8 in. thick.
