OSTI ID:4060919
The counter described has the following characteristics: a background of 2.40 cpm; a counting rate for modern carbon of 10.43 cpm; and an efficient volume of 0.570 1. It is used mainly for radiocarbon dating. Shielding is accomplished by 27 cm of iron and blocks of paraffin mixed with boric acid. The hard component of cosmic radiation is anti-coincidenced by means of 18 Geiger counters. (T.F.H.)
