SOME EFFECTS OF 400 MEV PROTONS ON PRIMATES. THE RADIATIONS OF SPACE IV

Primates were given spaced doses of 400 Mev protons. From the mortality data a lethal dosage 50/30 of 585 plus or minus 33 (S.E.) rads was calculated. Hematologic measurements, LDH and SGOT concentrations, Fe ferrokinetics, and histopathologic findings indicate the effects produced by the protons ar...

Zusammenfassung:	Primates were given spaced doses of 400 Mev protons. From the mortality data a lethal dosage 50/30 of 585 plus or minus 33 (S.E.) rads was calculated. Hematologic measurements, LDH and SGOT concentrations, Fe ferrokinetics, and histopathologic findings indicate the effects produced by the protons are virtually identical to those produced by equivalent doses of 2 Mev x-rays. The only differences in response were clinical; relatively more intense gastrointestinal and hemorrhagic signs occurred after proton irradiation than after similar doses of the x-rays.
