Ludlum Model 9-4 Ion ChamberLudlum Model 9 4 Ion Chamber The Ludlum Model 9 4 is a rugged air ionization chamber for performing beta gamma dose rate measurements over a five decade span ranging from 0 to 500 mSv h (0 to 50,000 mR hr). The ion chamber automatically compensates for changes in temperature and pressure. The chamber wall (including the instrument case) is 1000 mg cm2. A 1000 mg cm2 retractable beta shield allows beta measurement with a 7 mg cm2 window. The six
