Describes methods of measuring the three-dimensional flow field using a three-sensor hot-wire probe, with emphasis on the techniques developed by the author's group at the Pennsylvania State University. The hot-wire equations, data processing procedure, calibration techniques, and a discussion of various errors in the measurement are included. Some typical data acquired by thisprobe is also included.
Reports investigation into the radon dose from inhaled radon daughters during exposure indoors. The initial phase of the investigation comprised detailed measurements of radon daughter concentrations in each of four locations in the New York area. The investigation has now broadened considerably. Time-integrated measurements of radon concentrations and working levels have been obtained in twenty dwellings in New York and New Jersey in a two year period with which to estimate annual mean exposures of the inhabitants.
