Dr. N. Harley's major research interests are in the measurement of inhaled or ingested radionuclides, measurement of environmental radioactivity, the modeling of their fate within the human body and the calculation of the detailed radiation dose to the cells specific to carcinogenesis.

Recent reseach concerns the modeling of indoor radon concentration and why it varies. To view a 5 year data base showing the major effect of
