Visualization of Radiation Scattering in an X-ray Room for Teaching Radiation Protection

Abstract

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.
