Atmospheric distribution of 85 Kr simulated with a general circulation model
A three-dimensional chemical tracer model for the troposphere is used to simulate the global distribution of 85Kr, a long-lived radioisotope released at northern mid-latitudes by nuclear industry. Simulated distributions for the period 1980–1983 are in excellent agreement with data from six latitudi...
