Neutron Activation Procedures for Silver Analysis in Precipitation
Publisher: American Meteorological Society
Abstract: Laboratory techniques have been developed for concentrating and isolating silver from aqueous samples. When these concentrated samples are activated in a thermal neutron flux of 4 ? 1012n cm?2 sec?1, quantitative measurements ...
Neutron Activation Measurements of Silver in Precipitation from Locations in Western North America
Publisher: American Meteorological Society
Abstract: Thermal neutron activation methods have been applied to the determination of silver content in samples of hail, rain and snow. Hail and rain samples were collected in South Dakota in regions where AgI cloud seeding was ...
Assessment of Seeding Effects in Snowpack Augmentation Programs: Ice Nucleation and Scavenging of Seeding Aerosols
Publisher: American Meteorological Society
Abstract: Trace chemical analysis techniques have been used in a series of cloud-seeding experiments in the central Sierra Nevada with the ultimate purpose of distinguishing whether the submicron-sized aerosol particles used for ...
