Dear Mahmoudreza,
lung has a local density larger than its average density, due to its alveolar structure.
Look at the FLUKA manual, option MAT-PROP. Example 2 shows how to define a local density of Lung (1.05 g/cm3) with command
MATERIAL, as well as an average density (0.3 g/cm3) by means of option MAT-PROP.

Subject: [fluka-discuss]: which publication of ICRP has reported the lung density equal to 1.05 g/cm3
Dear FLUKA experts
During the lung tissue simulation, I encountered to 1.05 g/cm3 for lung tissue densiy in the flair material data library?
In which publication of the ICRP this value was reported? isn't it too high for lung? 0.26 g/cm3 would be a proper choise?
however, lung tumor (GTV/ITV)might have the same density as 1.05 g/cm3.
