This morning MSNBC had a similar article that included dose estimates. The
areas, shown on a map, receiving the maximum dose had a dose of 3-10 mGy
over a long period. The period was not stated, but was probably 12 years.

........as a colleague here pointed out, " 3-10 mGy over a decade or so? If that's whole-body then we're talking ~10% of background exposure. If it's iodine or strontium the localized doses are higher (to the thyroid or bones, respectively), but still -- these aren't observable cancer-causing doses."

U.S. study ties 15,000 deaths to nuclear tests
Senator releases progress report on long-delayed study
By Miguel Llanos, MSNBC

FOLLOWS 1997 STUDY
The study was ordered after a 1997 study found that a single radionuclide, which is a by-product of above-ground nuclear testing, was tied to between 11,000 and 212,000 cases of thyroid cancer.
The new study examines 18 additional radionuclides linked to the tests, and addresses potential cancers in red bone marrow as well as the thyroid gland.

.........recall that the Fred Hutchinson Cancer Research Center in Seattle, which conducted the nine-year, $18 million study for the Centers for Disease Control and Prevention, found no link between offsite releases of radioactive iodine and increased thyroid disease among nearly 3,500 people born near Hanford between 1940 and 1946.
I have seen some fallout isopleth maps showing areas of higher readings running due north and extending well into Canada (southern Saskatchewan, etc.).
The Hanford Thyroid Disease Study (HTDS) web site is at <http://www.fhcrc.org/phs/htds/>
......three separate fallout maps from the new "unreleased" study are at :
http://msnbc.com/news/717299.asp
..........the MSNBC article says that " Fallout from U.S. tests in Nevada spread substantial amounts of radioactivity across many states, particularly Nevada, Utah, Idaho, Colorado, Kansas, Nebraska, Iowa and Missouri..........Heavy pockets from both sources of fallout were found in Iowa, Tennessee, California, Oregon, Washington and Idaho."
.....which shows that there was substantial fallout in the due north direction - not just west-east.
