Comparison between short- and long-term measurements of radon concentration in dwellings of upper silesia (Poland)

A Comparison of Winter Short-term and Annual Average Radon Measurements in Basements of a Radon-prone Region and Evaluation of Further Radon Testing Indicators

“…The geometric mean of the basement short-term concentrations overestimated the geometric mean of the basement annual concentrations (181 Bq m −3 , GSD=2.0) by 18 Bq m −3 . A similar trend was observed in a survey of more than 300 residences in Poland by Wysocka et al (2004) and in a study of 709 New Jersey homes by Klotz and colleagues (1993) where the average of four-day winter basement radon measurements also overestimated their corresponding annual average basement radon concentrations by 34 and 8 Bq m −3 , respectively.…”

“…Previous studies that compared short-term radon measurements to long-term measurements on the same floor did not incorporate methods that maximized the reliability (e.g., accuracy, precision) of the short-term radon test (Ruano-Ravina et al 2008 Wysocka et al 2004 Klotz et al 1993). For example, the E-PERMs used in this study are not affected by humidity (Rad Elec, Inc) and provide a true integrated mean radon measurement.…”

“…Indoor radon concentrations can exhibit significant temporal variability (Klotz et al 1993 Steck 1990 Ruano-Ravina et al 2008 Wysocka et al 2004) and are affected by housing factors (e.g., forced air heating system) and occupant practices (e.g., air conditioner usage) (Field et al 1993). A specific aim of this study was to determine the temporal agreement between short-term and annual radon airborne measurements that were both collected at the same location in the lowest livable level of homes in the state of Iowa.…”

Predictability of radon airborne measurements based on surrogate measures

“…The variance inflation factors (VIF) for each variable in all the final regression models were close to one, indicating that the predictor variables were not strongly correlated (i.e., multicollinearity). was observed in a survey of more than 300 residences in Poland by Wysocka et al (31) and in a study of 709 New Jersey homes by Klotz and colleagues (32) where the average of four-day winter basement radon measurements also overestimated their corresponding annual average basement radon concentrations by 34 and 8 Bq m -3 , respectively.…”

“…Indoor radon concentrations can exhibit significant temporal variability (29)(30)(31)(32)(33)(34) and are affected by housing factors (e.g., forced air heating system) and occupant practices (e.g., air conditioner usage) (28). A specific aim of this study was to determine the temporal agreement between short-term and annual radon airborne measurements that Once case and control ascertainment was completed, a contact letter describing the study was mailed to the potential participants.…”
