核子密度仪具有其它检测方法所不具备的检测准确、快速、经济和无损检测等优点,但由于核子仪使用了同位素放射源,出于对辐射的忧虑,许多人希望获得一种不使用同位素也可以准确快速地进行密度和水分测试的手段,即无核技术。在过去,先后有数十种无核密度和湿度检测技术形成商品。新技术的应用加速了工程建设的速度,无核密度仪无疑是一种新型设备,但从使用情况来看,使用范围小,应用实践少仍制约着它的发展。本文结合兰州特有的地质条件,充分论证土壤无核密度仪在兰州永登地区所测的数据的准确性,对无核密度仪广泛的投入使用具有重要意义。
Nuclear densitometers have the advantages of accurate, rapid, economical and non-destructive testing that other detection methods do not have. However, due to the use of isotope radioactive sources by nuclear instruments, many people are anxious about obtaining radiation without using isotopes The means by which density and moisture can be measured accurately and quickly, ie without nuclear technology. In the past, there have been dozens of non-nuclear density and humidity detection technology to form a commodity. The application of new technology accelerates the speed of construction. Nuclear density meter is undoubtedly a new type of equipment. However, its use range is small and its practical application still restricts its development. In this paper, Lanzhou unique geological conditions, fully demonstrated soil non-nuclear density meter in Lanzhou Yongdeng accuracy of the measured data, a wide range of non-nuclear density meter put into use is of great significance.
