The methods of detection and measurement of radioactive contaminants in air and gases are described. The direct methods examined are measurements using the scintillation chamber for alpha particles, ion currcnt detection instruments, pulse ionization chamber, and the proportional counter. The indirect methods examined are the analysis of activities obtained by filtration of air, by electrostatic precipitation, by filtration of air through adsorbing materials, differential separation and collection of air dust by impact, and by collection of dust from the flow (fall-out). 28 references.
