>Results are in and Simpkin, Dixon, Archer win (even disallowing Dr.
>Simpkins response).  50% liked their methodology due to factors such as:
>
>use of parameters refelecting modern equipment; accounting for
>attenuation by patient, cassette, bucky and table; workloads are more
>reflective of modern facilities; etc.  The 30% that still use 49 do so
>because:  comfort with the conservatism in that method; regulatory
>requirements force them to use it; or feel that until the NCRP gives any
>
>other method approval, 49 remains the gold standard.   20% use a hybrid
>of both methods.
