Isotopic Measurements at Broadlands

Abstract

Measurements were made on samples from Broadlands area in 1976 for many as to assess their usefulness for understanding the allow between the measurements and to with results for. purpose with a wide of half-lives were (5735 years), (12.5 years), (4.8 days)). are related to different aspects of the system. Carbon-14 levels were very low where is percent of the standard) because of extensive dilution by old from rock or sources. (high of the dilution with old A t Wairakei, wells are may be sensitive measure of dilution by young Tritium contents are low and probably Tritium is a good indicator of inflow of young water into the geothermal aquifer. Even quite high proportions of 14C) groundwater would not be detected Broadlands because.
