     Paul,

     According to ISO 8529, the specific source strength for 241AmBe is
     6.6E-5 n/s/Bq.  The specific neutron dose equivalent rate at 1 m is
     2E-19 Sv/s/Bq.  The specific photon dose equivalent rate at 1 m is
     1.9E-19 Sv/s/Bq.  The photon fluence and does equivalent rates depend
     on whether the source has been wrapped in lead (and how much.)

     ISO 8529, "Neutron reference radiations for calibrating
     neutron-measuring devices used for radiation protection purposes and
     for determining their response as a function of neutron energy."
