文摘

Part I Summary of relevant topics from 1923 to present—including: Currie (Anal Chem 40:586–593, 1968) detection concepts & capabilities; International detection & uncertainty standards; Failure of classical 14C dating and birth of new scientific disciplines; Exploratory nuclear data analysis of 85Kr monitors found coincident with the collapse of the Iron Curtain (1989); Faulty statistics proved responsible for mistaken assertions that Currie’s L_C yields excessive false positives; Low-level counting and AMS for atmospheric 37Ar and µmolar fossil/biomass carbon in the environment; Erroneous assumption that our low-level background is a Poisson Process, linked to ~8 % spurious anticoincidence events.
