Description/Abstract:
LIVESTOCK. THE PRIMARY HEMATOLOGICAL RESPONSE IN SHEEP AND CATTLE EXP OSED TO THE DIFFERENT COMPONENTS OF FALLOUT RADIATION WAS THE DROP IN PLATELET AND WHITE CELLS FROM WHOLE-BODY GAMMA EXPOSURE ALONE AND IN C OMBINATION WITH SKIN AND GASTROINTESTINAL EXPOSURES. SKIN AND GASTROI NTESTINAL IRRADIATION CAUSED MINOR BLOOD CHANGES WHICH APPEAR TO BE IN SUFFICIENT IN MAGNITUDE TO ACCOUNT FOR THE HIGH MORTALITY FROM THE COM BINED EXPOSURES. DATA ON SURVIVING CATTLE SHOW THAT SKIN AND GASTROIN TESTINAL IRRADIATION SEVERELY REDUCED ANIMAL PRODUCTIVITY. SHEEP FED 44 TO 88 MICRONS FALLOUT SIMULANT RESPONDED SIMILARLY TO THOSE FED LAR GER PARTICLES. RATE OF PASSAGE OF THE SIMULANT WAS REDUCED BY INCREAS ING THE LEVEL OF FALLOUT SIMULANT FED. SWINE ARE LESS SENSITIVE TO GA STROINTESTINAL FALLOUT SIMULANT ALONE AND IN COMBINATION WITH WHOLE-BO DY EXPOSURE IN COMPARISON WITH CATTLE AND SHEEP. FIELD CROPS. VARIET IES OF CORN (ZEA MAYS L. 'WF-9 X 38-11' AND 'GOLDEN BANTAM') AND OF SO YBEAN (GLYCINE MAX L. MERRILL 'KENT' AND 'HILL') WERE EXPOSED TO COBAL T 60 GAMMA RADIATION AND GROWN TO MATURITY UNDER OUTDOOR CONDITIONS. CORN WAS MORE SENSITIVE TO IRRADIATION THAN SOYBEANS AND YIELD WAS MOR E SEVERELY AFFECTED THAN SURVIVAL AND HEIGHT. EXPOSURES DELIVERED AT A HIGH RATE WERE MORE EFFECTIVE THAN THE SAME EXPOSURES DELIVERED AT A LOW RATE. PLANTS IRRADIATED IN EARLY DEVELOPMENTAL STAGES WERE SOMEW HAT MORE TOLERANT THAN AT LATER DEVELOPMENTAL STAGES; YIELD WAS MOST S EVERELY AFFECTED DURING THE EARLY REPRODUCTIVE STAGE. VARIETAL DIFFER ENCE IN RADIOSENSITIVITY WAS GREATER IN CORN THAN IN SOYBEANS.
