Summary:

Nuclear emulsions were used to detect radioactivity in Hawaiian lavas. The rocks studied were the trachyte from Hualalai, andesine-andesite from Mauna Kea, nephelite-melilite basalt from Moiliili quarry on Oahu, oligoclase andesite from Kohala on Hawaii, and olivine basalt from Mauna Loa on Hawaii. The results revealed slight radioactivities which were within the range reported for other basic rocks. The distribution of radioactive elements in Hawaiian lavas was more uniform than the distribution of granite. Radioactivity does not seem to contribute a major portion of the heat of volcanoes.
