Exploring Seasonal Variation of Indoor Radon in Campania: Preliminary Findings

This study focuses on the indoor radon gas monitoring in 30 residences in Campania to evaluate seasonal variability. Approximately 570 CR‐39 solid‐state detectors were employed. Measurements were taken monthly, quarterly, semiannually, and annually, starting in October 2022 and ending in September 2023. The seasonal variability was assessed using the Gini coefficient, with quarterly and semiannual values being comparable at 6% and 7%, respectively, while the monthly measurements exhibited a higher Gini coefficient, 13%. The measurements were conducted in accordance with the UNI ISO 11665‐4:2021 standard. This preliminary study investigates the seasonal variability of radon concentration in Campania. The results obtained may support future research on a larger scale.
