X-ray irradiation of KDP-K_2SeO_4 mixed crystal is shown to produce SeO_4^<3-> and SeO_3^- radicals. The ESR spectrum of SeO_4^<3-> has well-resolved proton hyperfine structure which exhibits the "quintet to triplet" transition as seen on AsO_4^<4-> radical in KDA. This radical may be used as a new "probe" to study the proron dynamics of KDP. The tensors of hyperfine interaction with Se^<77> for these radicals are evaluated from the angular dependence of ESR spectra of the radicals. The principal-values of the hyperfine tensor of SeO_4<3-> are as follows, T⫽=3389MHz and T⊥=3178MHs in the paraelectic phane, and T_1=3055MHz, T_2=2986MHz and T_3=3490MHz in the ferroelectric phase.
