Plutonium is injected into the stratosphere by large atmospheric thermonuclear explosions. When aerosols bearing plutonium reenter the troposphere, they are removed by such processes as rainfall and sedimentation. In this work, the mean tropospheric residence time of stratospherically injected plutonium is calculated. A mean residence time of 71 days was obtained for the Northern Hemisphere. Calculated residence times showed little variation by geographic location or for different years.
