title: [Sensitivity of biological objects to the effects of the geomagnetic field].
abstract: It is shown on the basis of calculations of energy sublevels of the hyperfine structure that the effect of the geomagnetic field upon the impurity atoms in the volume of living cells should be considered in relation to the value of geomagnetic field induction pulses delta B. When delta B > or = 10 pT and the dielectric constant epsilon > or = 10, magnetodipole transitions between sublevels of the hyperfine structure within one term are possible in impurity atoms in their 2P-state. During magnetic storms with delta B > or = 100 nT magnetodipole or magnetoquadrupole forced transitions from 2P1/2 and 2P3/2 states to 2S1/2 metastable state are possible in the resonant zones formed by intersection of hyperfine energy sublevels of the corresponding excited levels.
