Abstract
We present the preliminary findings of our XMM-Newton Survey performed in the hard band [7-11] keV. The survey covers nearly 30 squares degrees for a total of 112 fields observed. We detected in the [7-11] keV band, down to a limit flux of about 3*10^(-14) erg cm^(-2) s^(-1) a total of 45 sources, 30% of which show strongly absorption. A detailed spectral characterization of these sources allows us to constraint the local N_H distribution.
