Abstract : Some of the implications of new rules set forth in the report named in the title concerning exposure to proton radiations in space are discussed. The proposed formulae assigning precise values of Relative Biological Effectiveness (RBE- and Quality Factor (QF) to any given Linear Energy Transeer (LET) are evaluated for typical spectra of x-rays, flare produced protons, and neutron recoil protons. The results essentially reconfirm earlier assessments established on the basis of the recommendations in NBS Handbook 59. Since the report re-emphasizes the basic difference between low LET and high LET radiation with regard to residual damage from low dose rate exposures, operations provide ways and means for separate measurement of the two fractions of exposures to proton beams.
