四川省燃煤电厂粉煤灰制建材的辐射影响预断评价

PRE-EVALUATION OF RADIATIVE EFFECT OF THE BUILDINGMA-TERIALSMADE OF THE COAL-DUST OF POWER STATIONS OF SICHUAN

本文根据四川省八大燃煤电厂粉煤灰的天然辐射水平,使用KarPov及UNSCEAR报告提供的方法,估算了全省八大电厂粉煤灰所制建材给居民带来的附加辐射剂量(0.3～1.6mSv/a),推算出全省各大电厂粉煤灰在建材中满足国家放射标准的最大允许掺和量(54％～100％)。

According to the natural radiant level of the coal-dust in eight fire-coal power stations of Sichuan, this article estimates the additional radiation dose (0.3～1.6mSv/a) of the building-materialsmade of these eight power stations bring to the habitant by using the methods provided in the reports of Kar For and UNSCEAR, and calculates the maximun mixture of the coal-dust in the building materials that meets the demand of national radiant stardand in every large power station in the whole province.
