Wind speeds at jet streak levels (about 30,000 ft) have been rapidly west to east across the Pacific Ocean and the United Sta over 100 miles per hour.
Small amounts of radioactivity that mixed upward to Ehese levels from the Chernobyl nuclear accident have aircraft flying off the northwest U.S. coast.
Therefore, patches of activity are now moving across North America at high altitudes.
The most likely source of early detection near the ground will be in rainwater, particuiar darstorms reaching altitudes of 20,000 to 30,000 ft. or more.
As of this time,
(
it 'is believed that concentrations in rainwater will not .
be dang Activity at lower altitudes is being transported less rapidly and will proba the U.S. during subsequent days.
