Recent exposure to particle radioactivity and biomarkers of oxidative stress and inflammation: The Framingham Heart Study.

ABSTRACT:

Background

Decay products of radioactive materials may attach to ambient fine particles and form radioactive aerosol. Internal ionizing radiation source from inhaled radioactive aerosol may contribute to the fine particulate matter (PM_2.5)-inflammation pathway. However, few studies in humans have examined the associations.

Objectives

To examine the associations between particle radioactivity and biomarkers of oxidative stress and inflammation among participants from the Framingham Offspring and Third Generation cohorts.

Methods

We included 3996 participants who were not current smokers and lived within 50 km from our central air pollution monitoring station. We estimated regional mean gross beta radioactivity from monitors in the northeastern U.S. as a surr
