众所周知,用放射性测量方法测密度可以分γ射线吸收法及散射γ射线吸收法两类。我国野外队以采用γ射线吸收法测定岩(矿)石密度者居多。利用散射γ射线法测密度至今仍很少。虽然散射γ射线法测密度与γ射线吸收法相比具有打炮孔少,工作方法简单,生产效率高等优点。究其原因,主要是在开展散射γ法测密度时需要结合具体情况制作密度量板,
As we all know, with the radioactive measurement of density can be divided into γ-ray absorption and scattering γ-ray absorption method of two categories. Our field team to use gamma ray absorption method to determine rock (ore) stone density are mostly. Density measurements using scattered gamma-ray are still rare. Although the scattering gamma ray method to determine the density compared with the gamma ray absorption method has a small hole blowing, the working method is simple, high production efficiency. The reason, mainly in the conduct of scattering γ density measurement methods need to be combined with the specific circumstances of the density plate,
