Variation in ozone concentration and volumetric activities of radon progeny on the Curonian Spit

Anotacija

This paper presents the study of variation in ozone concentration and volumetric activities of radon decay products as well as their relationship at the ground level of the atmosphere on the Curonian Spit. The simultaneous measurements of the ground-level ozone concentration and volumetric activity of radon progeny gave a possibility to identify the presence of a breeze phenomenon on the Curonian Spit during an extreme weather event in summer when ozone concentration exceeded the target value of 120 µg m⁻³ that can have a negative impact on human health. The evident influence of wind direction on ozone concentration and volumetric activity of radon progeny was estimated.
