Dear experts!
I was tested how many atoms are in per 3 nm gold nanoparticle and compared it with some experimental work. In Geant4.10.07, it was counted about 219 gold atoms by via the function “GetTotNbOfAtomsPerVolume()” , whereas there were about 479 gold atoms per nanoparticles in the experimental work.
The material was considered as the Au197 isotope with a 19.32 g/cm³ density.
In this case, is it normal to calculate and validate for the radio-enhancement effect?
Best wishes,
