Abstract
Elevated 222Rn levels in modern homes that had low air interchange rates with the out-of-doors prompted a survey of solar and conventional homes in northeastern New York State [USA]. The solar homes as a group had 3-fold the 222Rn levels of the conventional homes, and specific problems existed that were introduced or exaggerated by modern construction. The highest 2 levels of Rn in the solar homes gave radiation doses over 30 yr that were known to produce lung cancer in 1% of homes gave radiation doses over 30 yr that were known to produce lung cancer in 1% of Ur miners. Summer readings in more than half of the cases were different from winter ones by a factor of .gtoreq. 2, so that year-round measurements were necessary for precise dosimetry. The track etching technique was suited for such measurements.Keywords
