Description/Abstract:
SOILS AND PLANTS FROM THE AREA OF CENTRAL AND NORTHEASTERN NEW MEXICO, WHICH WAS CONTAMINATED BY FALL-OUT FROM THE ATOMIC BOMB DETONATION OF JULY 16, 1945, WERE ANALYZED FOR PLUTONIUM. PLUTONIUM WAS FOUND IN AM OUNTS UP TO 0.07 MICROGRAMS PER SQUARE FOOT OF SOIL, ONE-HALF INCH DEE P, AT A DISTANCE OF 88 MILES NORTHEAST OF THE SITE OF DETONATION. A MA XIMUM OF 1.47 MICROGRAMS PER SQUARE FOOT, ONE-HALF INCH DEEP, WAS FOUN D ON THE CHUPADERA MESA AT A DISTANCE OF 28 MILES NORTHEAST OF THE DET ONATION SITE. NO PLUTONIUM WAS FOUND IN SAMPLES COLLECTED 3 MILES SOUT H OF THE SITE. IN ASSAYING FOR PLUTONIUM, THE METHOD OF EISENACHER WAS ADAPTED TO SOIL AND PLANT SAMPLES. AN ESTIMATED PRECISION OF PLUS OR MINUS 15 PER CENT WAS OBTAINED WHEN THE METHOD WAS APPLIED TO FIELD SA MPLES. A RECOVERY OF 98.0 PLUS OR MINUS 3.0 PER CENT WAS OBTAINED WHEN THE METHOD WAS APPLIED TO A "STANDARD" SOIL. URANIUM AND THORIUM DO N OT INTERFERE IN THIS METHOS EVEN WHEN THEY ARE PRESENT IN QUANTITIES M UCH GREATER THAN THE MAXIMUM AMOUNTS NORMALLY FOUND IN SOILS.
