Abstract
The report gives results of a study of short- and long-term variations in radon concentration in about 80 houses in Florida. The study involves comparative sampling using the most common radon measurement technologies during the past year. The study, providing the most detailed database addresses the time variation of indoor radon concentrations in a significant number of occupied houses having moderately elevated radon concentrations. In the study houses, the degree of variation of radon varies roughly in proportion to the long-term mean concentration, with a coefficient of variation within a calendar quarter of about 25% of the quarterly mean, and a coefficient of variation within a year of about 35% of the annual mean. The study indicates a distinct seasonal effect on the average radon, with quarterly averages relative to the annual average increasing in the order of spring (82%) < summer (93%) < fall (97%) < winter (123%).
