Description/Abstract:
VERTICAL DISTRIBUTIONS FOR BERYLLIUM-7, SODIUM-22, PHOSPHORUS-32, PHOS PHORUS-33, AND SULFUR-35 HAVE BEEN OBTAINED BY RADIOCHEMICAL ANALYSIS OF AIR-FILTER SAMPLES COLLETED BY AIRCRAFT IN THREE SETS OF ORBITAL FL IGHTS IN 1960, 1961, AND 1964 BETWEEN 4.6 AND 20 KM OVER 70 DEGREES NO RTH, 144 DEGREES WEST. CONCENTRATIONS OF STRONTIUM-89, STRONTIUM-90, R HODIUM-102, AND CADMIUM-109 WERE ALSO DETERMINED IN SOME SAMPLES. SUPE RSATURATION RADIOACTIVITY LEVELS WERE FOUND AT 12 KM IN ALL PROFILES F OR NATURALLY-PRODUCED PHOSPHORUS-32 AND PHOSPHORUS-33. IN MARCH 1964, SODIUM-22, AND SULFUR-35 EACH WITH A LARGE ARTIFICIAL COMPONENT, ARE M OST HIGHLY SUPERSATURATED AT 12 KM. FROM RADIOSONDE DATA, IT IS CONCLU DED THAT THE 12-KM EFFECT MAY BE EXPLAINED ON THE BASIS OF LARGE-SCALE DOWNWARD MIXING FROM REGIONS OF HIGHER PRODUCTION RATE TO 12 KM, WITH RELATIVELY INHIBITED MIXING TO LOWER ALTITUDES. SUPERSATURATION QUANT ITIES OF PHOSPHORUS-32 AND PHOSPHORUS-33 IN THE TROPOSPHERE IN MARCH 1 64 ARE CONSIDERED TO BE EVIDENCE OF TRANSPORT ACROSS THE TROPOPAUSE. S OME DATA SUPPORTING THE EXISTENCE OF PHOSPHORUS-32 AND PHOSPHORUS-33 S UPERSATURATION AT OTHER LOCATIONS ARE CITED. IN CONTRAST TO THE OTHER NATURALLY-OCCURING RADIONUCLIDES, LEVELS FOR BERYLLIUM-7 WERE FOUND TO BE HIGHLY UNDERSATURATED.
