URI allows for multiple pathways and multiple calculation methods, so one could conceivably use the effluent stack pathway combined with Containment radiation monitors to quantify the release. Personally, I'd rather use Field Team data than taking dose rate reading on a stack to quantify the release since it would be more representative of "actual" release.

Does anyone have an alternative or additional method of estimating an accident releases-such as taking radiation readings on the effluent stack, or providing an additional stack monitor of some kind?
