(The summary shall include to the extent practicable an estimate of individual radionuclides present in the effluent. If the estimated average release after dilution or diffusion is less than 25% of the concentration allowed, a statement to this effect is sufficient.);

Thirteen areas (Numbered from 1 to 13) were monitored for the entire calendar year. A list of these numbered areas can be found in UFTR SOP. Note that among them, Area No. 2, which is the stack area, has the highest dose record. And 3 separate areas in the reactor building were monitored during the same time period.
