Setting a Limit on Anthropogenic Sources of Atmospheric 81Kr through Atom Trap Trace Analysis

We place a 2.5% limit on the anthropogenic contribution to the modern abundance of 81Kr/Kr in the atmosphere at the 90% confidence level. Due to its simple production and transport in the terrestrial environment, 81Kr (halflife = 230,000 yr) is an ideal tracer for old water and ice with mean residen...
