These problems are low energy photon and its thin glare was mainly used to in the past, did not greatly matter. However, the recent 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, in recent years the industrial x-ray scintillator 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, industrial x-ray flash itself, become a problem.
