Triglycerides, cholesterol, total lipids and phospholipids levels were
investigated in the serum of rats after cumulative whole body gamma i
rradiation at doses from 2.5 to 10 Gy. Hyperlipidemia was observed aft
er irradiation doses of 7.5 and 10 Gy. Different mechanisms were postu
lated for the radiation induced changes in the levels of serum lipid.
