Low-resolution gamma-ray measurements of process hold-up

Abstract This tool, consisting of software with a compact detector, an M3CA, and an Intermec datalogger: 1. 1. acquires and manages several hundred spectra in an hour; 2. 2. produces prompt and reliable quantitative analyses; 3. 3. is self-powered, easily carried and operated by a single user; 4. 4. accomodates varying degrees of user expertise; 5. 5. corrects for the effects of equipment geometry; 6. 6. corrects for the effects of equipment attenuation; 7. 7. tolerates facility variables such as temperature fluctuations and equipment accessibility; 8. 8. has been subjected to quality testing under field conditions; and 9. 9. does not require extensive specialized training for the operators.
