title: [Effects of single and chronic low-intensity irradiation in small doses on K+ transport in brain slices].
abstract: Single and/or chronic X-ray low-intensity irradiation in doses from 0.01 up to 0.5 Gy invokes non-linear, oscillatory changes of K+ content in a native tissue of rat brain, and also of Na,K-pump activity in slices of rat brain cortex, incubated in vitro. It is found out that effects of separately taken equal doses of single and chronic exposure are of unequal means or of diverse directions. Thus the single irradiation is characterized by the lower degree of postradiation recovery processes.
