It is a technical issue of choosing one Build Up Factor(BF) material when a contaminated water in a iron tank of that thickness is "a thin layer condition" to calculate a dose of tank surface by using the simple shielding calculation code(like QAD). To understand a suitable setting, We set benchmark probrem and carried out a Monte-Calro Calculation.
