【 摘 要 】

References(20)We screened urinary iodine (UI) concentrations in high background radiation areas of the Kanyakumari district of Tamilnadu, India. We collected 331 urine samples from three villages in the district: Chinna-Villai, Kadiyapatinam, and Pallam-Annai nagar. The median UI concentrations were 257, 262, and 454 μg/L in Chinna-Villai, Kadiyapatinam, and Pallam-Annai nagar, respectively. Only 27 samples showed mild or moderate iodine deficiency (<100 μg/L) and none showed severe deficiency (<20 μg/L). These findings indicate that iodine supplementation in the villages is sufficient, probably as a result of appropriate fortification of iodized salt in the region. Further screening, including morphological and functional analysis of the thyroid gland, will be needed to clarify the health effects of chronic low-dose radiation exposure attributable to residing in a high background radiation area.
