>Dear All
>Our regulatory body in revamping the Radiation Regs has for disposal
matters largely followed NRC guidelines. However NRC - CFR Part20 clearly
excludes patient excreta from the concentration limits. 
>Can anyone enlighten me as to the thinking behind this and whether there
are alternative concentration limits which apply in this case.
