从同位素水文学视角看水体中氚等核素的监测研究

Key Points

• Tritium concentrations in global precipitation have been decreasing over the past 60 years, not increasing.
• The analysis focused on data from representative sites including Edmonton, Vienna, and Hong Kong.
• Data was derived from the GNIP database maintained by IAEA and WMO, covering a time series of atmospheric tritium levels.
• The findings highlight the need for enhanced monitoring of isotopes like tritium for environmental radiological safety.
