To compare caesium-137 concentrations in patients from the Western Isles Health Board, Glasgow area, and other parts of the Scottish mainland, and to investigate the source of 137Cs in patients from the Western Isles.
Study of hypertensive patients having electrolyte concentrations measured, including 137Cs. Interview by questionnaire of island subjects about intake of foods likely to contain radiocaesium and the source of these foods. Measurement of 137Cs and 134Cs in food, urine, and vegetation.
Scottish mainland and Western Isles, 1979-86. All measurements before Chernobyl nuclear accident.
413 consecutive patients referred to the blood pressure unit for investigation of hypertension. 60 from the Western Isles, including 44 from North Uist; 32 from North Uist participated in the dietary analysis.
Concentration of radiocaesium in the body, urine, food, and vegetation. Islanders' consumption of local produce.
Patients from the Western Isles had five times higher body concentrations of 137Cs (median 2.54 (interquartile range 1.25-3.73)) Bq/gK) than did patients from around Glasgow (0.47 (0.26-0.66) Bq/gK) and other parts of the Scottish mainland (0.42 (0.24-0.71) Bq/gK). Islanders often consumed local milk and mutton, but ate local fish rarely. 137Cs and 134Cs were present in coastal (21.6 Bq/kg 137Cs, 0.25 Bq/kg 134Cs) and moorland (135.9, 0.65 Bq/kg) grasses and in islanders' urine (2.01, 0.013 Bq/l). Lower concentrations (0.336, 0.004 Bq/l), were found in the urine of Glasgow controls (p less than 0.001 for both isotopes).
Islanders have excess body 137Cs concentrations, most of which probably comes from local milk and lamb. The radioactivity is not above the recommended safety limit. The presence of 134Cs suggests that nuclear reprocessing is the source of some of the radiocaesium.
比较西部群岛卫生委员会辖区、格拉斯哥地区以及苏格兰大陆其他地区患者体内的铯 - 137浓度，并调查西部群岛患者体内铯 - 137的来源。
对测量电解质浓度（包括铯 - 137）的高血压患者进行研究。通过问卷调查岛上居民关于可能含有放射性铯的食物摄入量以及这些食物的来源。测量食物、尿液和植被中的铯 - 137和铯 - 134。
1979 - 1986年的苏格兰大陆和西部群岛。所有测量均在切尔诺贝利核事故之前进行。
413名连续被转诊至血压科进行高血压调查的患者。其中60名来自西部群岛，包括44名来自北尤伊斯特岛；32名来自北尤伊斯特岛的患者参与了饮食分析。
体内、尿液、食物和植被中放射性铯的浓度。岛民对当地农产品的消费量。
西部群岛患者体内铯 - 137的浓度（中位数为每克钾2.54（四分位间距为1.25 - 3.73）贝克勒尔）是格拉斯哥周边地区患者（0.47（0.26 - 0.66）贝克勒尔/克钾）和苏格兰大陆其他地区患者（0.42（0.24 - 0.71）贝克勒尔/克钾）的五倍。岛民经常食用当地的牛奶和羊肉，但很少食用当地的鱼类。沿海（铯 - 137为21.6贝克勒尔/千克，铯 - 134为0.25贝克勒尔/千克）和荒地上的草（分别为135.9、0.65贝克勒尔/千克）以及岛民的尿液中（分别为2.01、0.013贝克勒尔/升）都含有铯 - 137和铯 - 134。在格拉斯哥对照组的尿液中发现的浓度较低（0.336、0.004贝克勒尔/升）（两种同位素的p值均小于0.001）。
岛民体内铯 - 137浓度超标，其中大部分可能来自当地的牛奶和羊肉。放射性不高于推荐的安全限值。铯 - 134的存在表明核后处理是部分放射性铯的来源。
