It is important to reduce avoidable radiation exposure of health care workers and patients at radiography room in hospitals. For this purpose, teaching methods/tools that can explain basics of radiation protection is useful. Here, we propose a new teaching tool for radiation protection at a general radiography room. X-ray scattering at the general radiography room is mapped by using a Monte Carlo simulation code, PHITS. The radiography room is modeled with a simple geometric form. Therefore, the model can be changed easily to fit each radiography room even by a PHITS beginner. Visualization of X-ray scattering in each radiography room help the effective understanding of radiation protection. Our teaching tool is useful to reduce the unnecessary radiation exposure in radiography rooms.

Key words: radiation protection; teaching method; general radiography; Monte Carlo simulation; PHITS
