The electromagnetic transitions of the doublet bands with different triaxiality parameter {gamma} are discussed in the particle rotor model with {pi}h{sub 11/2} x {nu}h{sub 11/2}{sup -1} configuration. It is found that B(M1) staggering as well as the resulting B(M1)/B(E2) and B(M1){sub in}/B(M1){sub out} staggering are sensitive to the triaxiality parameter {gamma}, and they associate strongly with the characters of nuclear chirality for 15 deg. {<=}{gamma}{<=}30 deg., i.e., the staggering is weak in the chiral vibration region while strong in the static chirality region. For partner bands with near degenerate energy spectra and similar B(M1) and B(E2) transitions, the strong B(M1) staggering can be used as a fingerprint for the static chirality.
