Following the Chernobyl accident, Austria was one of the most contaminated Western European countries. Predictions of internal dose in humans due to this contamination were based on the average activities in major dietary products and average consumption rates. We have measured the amount of radiocesium in human adult muscle samples obtained at forensic autopsies within a limited area in Southern Austria over a period of 4 yr. From the measurements, we have estimated a mean individual effective dose equivalent of 252.2 muSv (25.2 mrem) due to internal exposure to radiocesium during this 4-yr period. This estimate, based on actual measurements, is approximately 25% of the predicted dose and is less than 50% of the dose received in the body from naturally occurring potassium-40. Comparisons of radiocesium activities measured in muscle tissues with data obtained after nuclear weapons tests and whole-body countings are given.
切尔诺贝利事故之后，奥地利是受污染最严重的西欧国家之一。此次污染导致人体内部剂量的预测是基于主要膳食产品中的平均活度以及平均消费率。我们测量了在4年时间里于奥地利南部一个有限区域内法医尸检时获取的成年人类肌肉样本中的放射性铯含量。根据这些测量结果，我们估算出在这4年期间由于体内暴露于放射性铯，个体平均有效剂量当量为252.2微希沃特（25.2毫雷姆）。基于实际测量得出的这一估算值约为预测剂量的25%，且小于人体从天然存在的钾-40所接受剂量的50%。文中给出了肌肉组织中测量的放射性铯活度与核武器试验及全身计数后获得的数据的比较结果。
