Medical examinations performed on four monks of a monastery in the northern Greece revealed heavy metal contamination. Hair analysis, performed by a toxicological laboratory abroad, indicated, among other, the presence of uranium. The uranium concentrations determined in a laboratory of "Elemental Hair Analysis' indicated a uranium level that was about five times the maximum value of the reference range, which has been adopted by the measuring laboratory. After these diagnostic findings, on request of 10 monks, uranium determination in hair and urine samples was performed by means of alpha spectrometry in GAEC's laboratory. The measured uranium concentrations in hair varied from 0.15 to 2.10 mBq g(-1), which correspond to 12.1 and 170 ng g(-1), respectively. The uranium concentrations in urine were between 41 and 174 ng d(-1). For comparison purposes, urine and non-dyed hair samples from the staff of the laboratory were analysed. Because one of the major sources of uranium intake is through drinking water, water samples were also analysed. The mean value of the uranium concentration in the two drinking water samples collected from the residence area was found to be 2.35 μg l(-1).
对希腊北部一座修道院的四名僧侣进行的医学检查显示存在重金属污染。由国外一家毒理学实验室进行的头发分析表明，除其他元素外，还存在铀。在“元素头发分析”实验室测定的铀浓度表明，铀含量约为测量实验室采用的参考范围最大值的五倍。在这些诊断结果出来后，应10名僧侣的要求，GAEC实验室通过α能谱法对头发和尿液样本中的铀进行了测定。测得的头发中铀浓度在0.15至2.10 mBq g(-1)之间，分别对应于12.1和170 ng g(-1)。尿液中的铀浓度在41至174 ng d(-1)之间。为作比较，对实验室工作人员的尿液和未染色头发样本进行了分析。由于摄入铀的主要来源之一是饮用水，因此也对水样进行了分析。从居住区域采集的两份饮用水样本中铀浓度的平均值为2.35 μgl(-1)。
