High-altitude sampling program.

The High Altitude Sampling Program was initiated
by the Joint Chiefs of Staff in 1954 to determine the
spread of weapon produced fission products through the
stratosphere. U-2 aircraft operated by the Strategic Air
Command have been sampling stratospheric air at various
altitudes along North-South paths from 66{sup 0}
to 57{sup 0} South at 70{sup 0} West since 1957.
North
Isotopes Incorporated, the principle contractor in this
program, has analyzed over 1500 samples to date. Further
metrological correlation has evolved a model of the
stratosphere which accounts for the non-uniform
deposition of fission products. The total stratospheric
inventory of
{sup 90}Sr as of the Fall of 1958 was
to be 1 megacurie. The half-residence time of polar
injections and equatorial injections into the
stratosphere was found to be six months
found
and twelve
months, respectively. The major portion of the
stratospheric debris moves into the troposphere through
the mid-latitude tropopause break. Predictions of {sup
90}Sr levels to be found in equilibrium bone have been
801.
