Abstract: The buildup factor will be used whilethe dose rate calculation is done according to cylindrical source formula in Handbook of Radiation Protection. There is not, however, too much description of the buildup factor caused by scattering effect of photon inside a cylinder in thehandbook. The factor is obtained with software simulation in this paper. A comparison is furthermore made between it and that of point source with slab shieldsof a thickness equivalent to the cylinder radius. And the approximate mathematical relationship between them is then provided.

Key words: Cylinder source, Point source, Exposure buildup factor
