Description/Abstract:
WASHINGTON NAVEL ORANGE LEAVES WERE IMMERSED IN SOLUTIONS CONTAINING T HE RADIONUCLIDES FE-59, ZN-65, CS-137, AM-241 AND PB-210 WITH AND WITH OUT THE CHELATING AGENT DTPA ( 10-4M ), AT PH VARYING FROM 2.0 TO 8.0 AND WITH AND WITHOUT THE RESPECTIVE STABLE NUCLIDES AS CARRIERS ( 10- 4M ) EXCEPT FOR 241-AM. LOW PH DECREASED THE UPTAKE OF ALL 4 RADIONUCL IDES. WITHOUT CARRIER THE UPTAKE OF 65-ZN INCREASED WITH PH 8.0 AS DID UPTAKE OF 241-AM. THE ADDITION OF CARRIERS DECREASED UPTAKE OF ALL 4 RADIONUCLIDES BUT CARRIER EFFECT WAS LEAST ON 137-CS. DTPA LARGELY NE GATED THE EFFECTS OF PH ON UPTAKE AND GREATLY DEPRESSED UPTAKE.
