I don't know if it helps but ICRP-116 contains a database  of "ICRP/ICRU
Database of Dose Conversion Coefficients;" for example, they have a table of
effective dose conversion coefficients in units of pSv cm-2 for various
geometries for 0.01 to 10,000 Mev.

Content preview:  I have run into a problem where I have a known intensity
   of photons - too small and too intense and too low an energy to actually
  measure with all but maybe one instrument - which I don't have and am not
  about to get - and I need to come up with a shield value. And even that is
   ridiculous since the beam cross section is so small it hard to decide how
   any regulatory limits apply. I think the get the actual DOSE rate - I'd
   to do monte carlo calculations - not going there. It not hard to come up
  with a energy flux and make assumptions about attenuation in say water and
   calculate RADs to water - or Sv if you must! [...]
