Abstract
SUMMARY A simple and convenient particle tracer for studies of the effectiveness of isolation units and other places in limiting the airborne transfer of bacteria is described. Particles of potassium iodide 7–8 µm. diameter are generated by spraying from solution and collected on membrane filters. The particles can be identified by development with 0·1 % acid palladium chloride solution, when dark brown spots approximately 100 µm. in diameter are produced.Keywords
