NOTES OF THE DEPOSITION OF FALLOUT IN RELATION TO TOPOGRAPHY AND LOCAL METEOROLOGICAL CONDITIONS [electronic resource]

Activities in a program to collect radioactive effluents released during the test operation of a Kiwi reactor (Kiwi B-la) on December 7, 1961, are reported. Granular fallout collectors and cheesecloth aerosol collectors were prelocated along roads approximating arcs of 5, 16, and 37 miles from the r...

520 3 |a Activities in a program to collect radioactive effluents released during the test operation of a Kiwi reactor (Kiwi B-la) on December 7, 1961, are reported. Granular fallout collectors and cheesecloth aerosol collectors were prelocated along roads approximating arcs of 5, 16, and 37 miles from the reactor test cell at the Nevada Test Site. Each of these arcs crossed successively lower and wider parts of a gently sloping valley. A last-minute shift in wind direction carried the effluent cloud away from the prelocated sampling devices. Apparently, the cloud was trapped until nightfall in an inversion layer from 2000 to 3500 feet above the surface. During the night following the reactor test, tropospheric or stratospheric fallout probably derived from nuclear detonations in the U.S.S.R. (but no short-lived fission products) were deposited on the abovementioned sampling devices. The shallow-valley inversion and cold air drainage caused the pattern of this deposition to be closely related to the local topography. The betagamma activity deposited on samplers at low elevation (presumably below the valley inversion layer) was less than that deposited on samplers at higher eleveations. The highest levels of beta-gamma activity were detected on samplers which had been located direcly in the most probable pathway of nocturnal cold-air drainage. Further studies are recommended.
