Summary

The proton energy spectra for the Class 2 solar flare of February 5, 1965, as reported by a polar orbit satellite at five different times during the two-day period of enhanced intensity, are evaluated in terms of tissue depth doses for a semi-infinite slab with 0.1 g/sq cm shielding and for the Gemini and Apollo shield distribution. Maximum dose rates for the tissue surface are 714 millirads/hour, 81 and 11 millirads/hour, respectively. For the unidirectional beams, half value layers range from 2.6 to 5.6 millimeters of tissue. The integral flare dose over forty-four hours is 8.3 rads for the tissue surface behind 0.1 g/sq cm shielding. (Author).
