odel 31 detects less than 3 dpm C 1 4 , /cc air with Cary 250-cc ion chamber, provides measurements reproducible to better than 1%, and operates for months with a single calibration. It is ideal for simplifying measurement of either gaseous or combustible non-gaseous radioactive samples. Gaseous samples to 250°C are collected in or passed through the ion chamber for static 3r continuous flow measurements. Far more precise and sensitive than liquid trapping equipment, a Model 31 with ion chamber costs less than $2,000. < APPLIED PHYSICS CORPORATION
