A cross-sectional study was conducted to examine the relationship between natural radiation exposure and Intima-Media
Thickness (IMT), an atherosclerosis indicator, among female residents in Karunagappally, Kerala, South India, which is known
to have areas with High Natural Background Radiation (HNBR) derived mainly from thorium. Cumulative radiation doses
received during childhood, adulthood, and entire life were estimated on the basis of annual indoor and outdoor radiation
doses and hours spent indoors and outdoors. In 2013-2014, IMT of the carotid artery was measured with ultrasonography
among 400 women aged 29-60 years living in Karunagappally. Since there were three subjects with outlying maximum IMT
values, corrected IMT values excluding those outliers were calculated. For statistical analysis, raw and corrected IMT values
were used. The regression analysis .. View More»
