USE OF La(140) AS RADIOTRACER IN (PRE-BUGGY) CHEMICAL EXPLOSIONS: PREPARATION AND DETERMINATION OF ITS REACTION WITH ENVIRONMENTAL MATERIALS

Abstract

The pre-Buggy experiment was designed to measure the fraction of vented radioactivity from a series of HE underground detonations containing radioactive sources. Capsules (29) containing curie amounts of La(140) were prepared. The level of gamma activity in each capsule was sufficient to provide a radiotracing of the debris which resulted from the detonation. In addition NRDL furnished 'always open' fallout collectors to sample the debris, and a low-geometry scintillation counter to measure its La(140) content. Particle size measurements of the debris indicated that La(140) was adsorbed on the surface of the soil particles. Some 96% of the activity was associated with sub-sieve particles representing only 8% of the mass and 90% of the available surface area.
