    PR # 31172                                                                   
     Powerful Radio Galaxies (PRG) have the radio properties which are ver       
     y similer to Radio Laud Quasars (QSR). The unified model suggest that       
      they are intrinsically similar objects observed from different angle       
     s. We can test this model by the X-ray observation of the PRG. The X-       
     ray properties of the PRG have not been investigated well. We selecte       
     d 3C99 and 3C300 considering their strong optical magnetude among the       
      PRGs. We suggest the observation of this two PRG to investigated the       
      unified model.
