These problems are low energy photon and its thin glare was mainly used to in the past, did not greatly matter. However, it is used a lot in recent years and energy-based industrial x-ray Flash in the body becomes a problem.
This problem has not been significant problems in the past was mainly used for low-energy photons with a thin scintillator thereof. However, the high-energy X-ray scintillator-based industry that are widely used in recent years is a problem.
the problem is that the energy of the photon, and according to the use of thin light mainly in the past is not a problem. however, in recent years, a lot of energy is based on the industrial x-ray flash itself, become a problem.
