该讲习班审查了在超低活度水平下测量放射性的所有技术的最新水平以及低本底探测器开发的所有方面。需要这样的探测器来研究物理过程，只有当所有干扰本底的来源都减少到非常低的水平时才能观察到这些物理过程。这些技术对于开发用于中微子研究、太阳中微子物理和中微子天体物理的下一代探测器，以及测量双β衰变过程和寻找宇宙中的暗物质至关重要。主题包括：实验放射性纯度要求，屏蔽探测器免受宇宙射线和局部放射性影响的方法，测量散装材料、气体和表面杂质的方法，材料净化技术，以及相关主题。该研讨会标志着位于加拿大萨德伯里的新的深地粒子天体物理国际设施(SNOLAB)的挖掘工作的开始。
This workshop examined the state-of-the-art of all techniques for measuring radioactivity at ultra-low activity levels as well as all aspects of the development of low-background detectors. Such detectors are needed to study physical processes that can only be observed when all sources of interfering background are reduced to a very low level. These techniques are essential to develop next generation detectors for neutrino research, solar neutrino physics, and neutrino astrophysics, as well as measurement of the double beta-decay process and the search for dark matter in the universe. Topics covered include: experimental radio-purity requirements, methods for shielding detectors from cosmic rays and local radioactivity, methods for the measurement of impurities in bulk materials, in gases, and on surfaces, techniques for materials purification, and related subjects. The workshop marked the beginning of excavation for the new international facility for deep underground particle astrophysics (SNOLAB), located in Sudbury, Canada.
