<p>PROBLEM TO BE SOLVED: To enable simultaneous display of a plurality of kinds of trend graphs when the trend graphs showing results of radiation measurements are displayed. SOLUTION: A real time trend graph 102 and a past trend graph 104 are displayed in a display screen 100. A magnified trend graph 106 is displayed in the past trend graph 104. An axis of ordinate has the same scale in these trend graphs, while an axis of abscissa is different in scale among the trend graphs. However, connecting points 108, 110, 112 of the trend graphs keep time continuity. A dose change at present can be estimated on the basis of a past change. The dose change at an optional segment in the past can be magnified to be grasped.</p> |
