Abstract

The penetrating radiation from 226Ra, 232Th and 40K in conventional building materials has been measured by gamma spectrometry. A simple model is applied to the results to calculate the external radiation dose for people living in a typical Spanish house constructed with these materials. The radioactivity concentrations in the building materials were found to be similar to those reported for other countries. The average specific concentrations of 226Ra, 232Th and 40K for the total of 125 samples analyzed ranged from 5 to 421, 3 to 266 and 11 to 599 Bq kg-1, respectively. The results are examined in the light of standards for indoor exposure adopted by the Federal Republic of Germany and the criteria set up in the OECD/NEA Report, 1979.

摘要

已通过伽马能谱法测量了传统建筑材料中镭 - 226、钍 - 232和钾 - 40的穿透辐射。将一个简单模型应用于测量结果，以计算居住在用这些材料建造的典型西班牙房屋中的人们所受到的外部辐射剂量。发现这些建筑材料中的放射性浓度与其他国家报告的浓度相似。在所分析的总共125个样品中，镭 - 226、钍 - 232和钾 - 40的平均比活度浓度分别为5至421、3至266和11至599贝克勒尔每千克。根据德意志联邦共和国采用的室内照射标准以及经济合作与发展组织/核能机构1979年报告中设定的标准对结果进行了审查。
