				effects in atoms and ions.

 	A new type of radiative corrections to parity nonconservation effects in atmos and ions has been studied in details. This type of rediative corrections is the electron self-energy type with electroweak interaction with virtual boson being neutral Z boson. The expansion in inverse powers of Z boson mass for zero- and one-potential terms in potential expansion of bounded electron propagator was obtained analytically.
	The relative size of the correction comparing to the ordinary radiative self-energy correction and interaction between bounded atomic electron and nucleus via Z boson was obtained. For atom Gadolinium the relative size of Z-boson loop correction turned out to be 1.6(3)%, which is a  significant value with respect to experimental accuracy about tenths of a percent.
