在辐射污染地区居民的长期累积辐射暴露中，慢性内部辐射污染占很大一部分。然而，关于受损的福岛第一核电站附近居民中持续存在的慢性内部辐射污染的信息很少。使用全身计数器，对2013年5月至7月(灾后26至28个月)在南相马市22所学校通勤的中小学生的体内辐射污染水平进行了评估。在全市3299名中小学生中，有3255人(98%)通过学校健康检查进行了筛查。没有一名学生被检测到由于放射性铯造成的体内辐射污染。研究发现，受损核电站附近的居民没有长期接触内辐射的风险。目前由地方政府、志愿者和农民进行的食品检查在福岛县内运作良好。然而，通过筛查疑似污染以及全身计数器筛查进行食品管理是关键的公共卫生干预措施，应继续进行，以避免在受辐射污染的地区进一步暴露于内部辐射。
Chronic internal radiation contamination accounts for a substantial fraction of long-term cumulative radiation exposure among residents in radiation-contaminated areas. However, little information is available on ongoing chronic internal radiation contamination among residents near the crippled Fukushima Daiichi nuclear power plant. Using a whole body counter, internal radiation contamination levels among elementary and middle school students who commute to 22 schools located within Minamisoma city were assessed between May and July 2013 (26 to 28 mo after the disaster). Of 3,299 elementary and middle school students in the city, 3,255 individuals (98%) were screened through school health check-ups. Not a single student was detected with internal radiation contamination due to radioactive cesium. The study found no risk of chronic internal radiation exposure among residents near the crippled nuclear power plant. Current food inspection by local governments, volunteers, and farmers has been functioning well within Fukushima prefecture. However, food management by screening suspected contamination along with whole body counter screening are key public health interventions and should be continued to avoid further internal radiation exposure in radiation-contaminated areas.
