What is a drinking water PAG?

The drinking water Protective Action Guide is a health-based value that can be used in the event of a nationally significant radiological emergency to determine when alternative drinking water should be provided and the use of contaminated water supplies be restricted.  The drinking water PAG are doses of radiation that should be avoided during an emergency event. They do not represent acceptable routine exposures. PAGs trigger safety measures—in this case, provision of alternative drinking water -- to keep doses to the public as low as possible during emergency situations only.
