Naturally occurring <sup>32</sup>Si and low-background silicon dark matter detectors
2018, Astroparticle PhysicsCitation Excerpt :In Ref. [11], e.g., Martoff notes that silicate rock sourced from deep underground should be low in 32Si because it has been isolated from the atmospheric 32Si source for a sufficiently long time. A later review by Plaga acknowledges 32Si as a potential background issue and advises use of silicate rock that has not mixed with ground water as a source material for low-background silicon detectors [12]. Plaga goes on to cite measurements in which water from deep wells showed 32Si activities of 0.04–0.06 decays/(kg d) [13], thereby cautioning that deep underground water may not be entirely free of 32Si; thus it is not certain that underground sources of silicate rock will necessarily be free of 32Si.
