RE: S.Korea Launches Probe Into Nuclear Accident

["Carroll,Raymond" <carrollrg@pgdp.usec.com>]

One other little tid bit.  Quality factors are not applicable for high acute
doses of radiation.  For more information you might want to research the
NCRP and ICRP documents.

The LD50/60 is normally quoted in Gy, not Sv.

Assuming Hisashi Ouchi received 1.7 SV, and assuming a neutron quality
factor of 10, one might guesstimate this is about 0.15 Gy gamma and 0.15 Gy
neutron. Would you expect this to be a fatal dose?
