摘要

The detailed characterization of ionizing radiation is essential for understanding occupational hazards as well as for planning scientific and industrial activities requiring well-defined conditions. The characterization of natural background radiation in the TU Bergakademie mine of Freiberg, Germany, which is one of the underground laboratories participating in the Baltic Sea Region's Underground Innovation Network (BSUIN), involves in-situ gamma spectrometry, neutron flux measurements, radon concentration, and alpha/beta laboratory spectrometry of water and rock samples. At a depth of 150 m within the gneiss formation (410 m w.e.), a neutron flux of (3.12 +/- 0.10) x 10(-6) [cm(-2) s(-1)] and a gamma ray dose of 0.036 +/- 0.008 mu Sv/h were determined.
