Emergency Response:
Using Environmental Monitoring Data
Emergency Preparedness
and Response
The RadNet (formerly Environmental Radiation Ambient Monitoring System) database is a rich source of radiation data from the environment around us. Used properly, the data can tell us a great deal. One example of its use is the long-term trends radionuclides in certain media. Below is the trend of tritium in precipitation.
Trend of H-3 (Tritium) in Precipitation
This trend is from monthly concentrations compiled between 1978-2001. (You can see the data on the Environfacts website.) Data came from samples of rainfall,snow, or sleet that fell throughout the month and were then combined into a single sample for each station.
