[ RadSafe ] Effluent Stack Monitoring

[John Andrews]

Make a plan that identifies the possible contaminants in the stack 
effluent.  This should include particulate and gasseous materials of 
interest and the appropriate sampling approach for each depending on the 
temperature and humidity of the effluent.

Plan a method of sampling the average flow from the stack.  Round stacks 
and square stacks are different.  Consider the distance from turns in 
thestack that would provide non-uniform flow rates in different parts of 
the stack.  If necessary propose to do a profile of the stack velocity 
to determine the appropriate point to sample the average flow.

If sampling particulates and especially if particles greater than 10 
microns will be present, plan to do isokinetic sampling.

Give us more information and we will provide more help.
