The log10 of survivors from radiation is plotted against the radiation dosage, and the radiation D or D10, which is comparable with the thermal D value, is obtained. The D10 is defined as the amount of radiation in rads (ergs of energy per 100g of material) required reducing the microbial population by 1 log (90%).

若将照射中存活微生物数目的log10值对照射剂量进行标绘，则可求出辐照D值(即D10值)，此值与热力D值相当。D10值的意义是微生物总数减少一个对数周期(90％)所必需的照射拉德数(每100克物质得到的能量尔格数)。
