Factors associated with elevated222rn levels in iowa

Abstract

The University of Iowa, in conjunction with the Environmental Protection Agency’s State Radon Survey Assistance Program, performed a222Rn screening survey of 582 rural households in the winter of 1989. The distribution of maximum indoor222Rn concentrations throughout Iowa as well as the relationship between222Rn screening measurements, detector placement, and housing characteristics are summarized. This report is unique in that site-specific home construction characteristics were collected in the field from participants prior to222Rn monitoring. The findings of the survey indicate that the significance of a particular housing characteristic on a222Rn screening measurement is dependent on the placement of the radon detector. © 1993 Health Physics Society Pergamon Press plc.
