.fl0TES :
'(1)
A complete sample is one in which the quantity of liquid sampled is proportional to the quantity of liquid waste discharge from the plant.
(2)
For certain mixtures of gamma emitters, it may not be possible to measure radionuclides in concentrations near their sensitivity limits when other nuclides are present in the sample in much greater concentrations.
Under these circumstances, it will be more appropriate to calculate the concentrations of such radio-nuclides using measured ratios with those radionuclides which are routinely identified and measured.
(3)
The detectability limits for activity analysis are based on the technical feasibility a'nd on the potential significance i,n the environment of the quantities released.
For some nuclides, lower detection limits may be readily achievable and when nuclides are measured below the stated limits, they should also be reported.
(4)
The pcwer level and cleanup or purification flow rate at the l
sample time shall also be reported.
i (5)
The Miscellaneous Water Evaporator is a batch liquid process involving change of phase from liquid to superheated steam, with at least 1200 fold volumetric expansion, the required detection 73..
levels are more conservative than batch gas release criteria.
