In this study, a model based on the Monte Carlo method was developed to investigate the radiation distribution produced by a Radiant Protective Performance (RPP) apparatus. Radiant Protective Performance (RPP) experiments were conducted to validate the model. It was found that the predictions of the model showed good agreement with the experimental data. Further, the results show a uniformly distributed heat flux area with a relatively high level at the center region of the incident surface of the test specimen. The radiation intensity image displays a high degree of similarity to the photo of the inside space of the RPP tester. The radiation intensity is obviously not parallel or uniformly distributed on the hemispherical space at the center of the specimen surface. The high level region corresponds to the lamp chamber. It was also found that the highest radiation intensity comes from the edge of quartz envelops nearby the gap.
