In the report "Particle size fractionation of airborne gamma-emitting radionuclides by graded filters" by B. Shleien, T. P. Glavin, and A. G. Friend (15 Jan., p. 290), the second sentence of the fourth paragraph should have read, "A rotary blower provided a sampling rate of 1400 liters per minute through the system."
