摘要:
由于粉煤灰和煤矸石均含有天然放射性，在再利用过程中，无论是制作建材，还是应用粉煤灰改良土壤，其中所含天然放射性物质对环境的影响，是人们关心的问题之一，也是关系到对它们的进一步开发利用的重要问题。本文通过对山西8个电厂粉煤灰中天然放射性核素含量测定，以及在农田施用粉煤灰后不同作物对放射性核素的积累和对用于制造建材的建筑物室内氡浓度的测定，进行了放射性安全评价，为其进一步资源化提供了依据。
Abstract:
This paper deals with the natural radioactivity contents of coal ash from Shanxi coal-fired electricity station and coal waste and their effects on the environment in the process of re-utilization of resources. The results obtained are as follows: 1.U and Th absorbed by crops are mainly located in the roots,and their magnitude is the highest in roots,higher in stem and foliage,and the lowest in seeds.The capacity of legume for absorbing Th is much greater than that of grass or that of the mustard family plants. 2.The concentration of Rn in the rooms built up of coal ash or coal waste is three times or two and half times as many as those built up of clay bricks,even higher than the value suggested by UNSCEAR in the report of 1977.Based on the above facts,circulation of air is an effective measure for reducing Rn concentration in the room.
