to see if a low dose of x rays could induce this response in cells at other phases of the cell cycle , human lymphocytes were irradiated with 0.01 or 0.05 gy before stimulation by phytohemagglutinin ( g0 ) or with 0.01 gy at various times after stimulation ( g1 ) , followed by 1.5 gy ( 150 rad ) at g2 phase .
