Adaptation to Stresses Induced by the Effects of External Low Dose Ionizing Radiation

Many human biology features may be explained by the absence of inverse correlation between T3 and T4 (except in the case of patients with thyroid diseases). The health of Russian cosmonauts may be superior to that of US astronauts because of the use of reserpine for radioprotection in the USA. As long as biologic age is inversely correlated to the α2-macroglobulin/α1-protease inhibitor ratio, so it would be interesting to study the selection of humans with elevated α2-macroglobulin contents for longitudinal interplanetary flights.
