Measurement of Radiation Angel and Dose Distribution for a Pulsed X-ray Source

It introduces 120-Ⅱ portalble pulsed X-ray source which radiate pulse X-ray when electrons from cold cathode bombard W-target,the pulse width is about 150 ns.Using LiF-dosimeter we measured the dose distribution on cross section of 30 cm far from radiatation point.The safe area for operator has been found by experiment.
