DIN 25462-2000《核裂变专用环境测量的现场伽玛射线光谱术》
The document deals with in-situ-gamma-ray spectrometry for nuclide specific environmental measurements of contaminations. The procedure is an evident and effective means to detect contaminations in the ground by gamma irradiating radionuclides and the resulting ambient dose rate of local single radionuclides. This is especially valid for dry or wet fall out/wash out contaminations.
