“Krypton-85 is a radioactive inert gas produced during
normal operations of the nuclear fuel cycle. The quantities
of krypton-85, that will be produced in the next century, are
sufficient, if released, to alter the electrical state of the
atmosphere. The principal hypothesis is that an anthropogenic–
alteration of the electrical state of the atmosphere could
alter other meterological phenomena and lead to significant
environmental impacts. The goal of this project was to explore
some areas of basic science related to the evaluation of that
The approach was primarily theoretical. The
following topics were addressed, (1) a first approximation
model to estimate the effects of krypton-85 on the electrical
state of the atmosphere; (2) an analysis of the pathways between
krypton-85 production and the atmosphere; (3) an analytical
model for fair weather atmospheric electricity, and (4) a dipole
model for atmospheric electricity. The results will provide a
framework on which detailed models can be built. The results
should provide better understanding of some topics in atmospheric
electricity.” Source: US DOE:
