Radiachromic: A radiation monitoring system

Radiation dose measurements of the insertion devices using radiachromic film dosimeters.

“…Upon exposure to ultraviolet light or ionizing radiation, these films undergo radiation-induced coloration by photoionization [12,14]. The photochemical reaction that takes place when the radiachromic films are exposed to ultraviolet light or ionizing radiation is displayed in Figure 1.…”

“…The photochemical reaction that takes place when the radiachromic films are exposed to ultraviolet light or ionizing radiation is displayed in Figure 1. The change from a clear or colorless state to a deep blue-colored state occurs gradually as a direct function of the radiation exposure received [12,15]. The change in the color intensity, or optical density, is measured using a radiachromic reader, or simple spectrophotometer.…”

“…They have an equivalent response to x-rays, γ-rays, and electrons from ultraviolet energies up to approximately 10 MeV [17,18,19]. Radiachromic films also have a dose rate independence to over 10 14 rads/s [12].…”

“…Radiachromic film dosimeters are nylon-based aminotriphenyl methane dye derivatives [12,13]. Upon exposure to ultraviolet light or ionizing radiation, these films undergo radiation-induced coloration by photoionization [12,14].…”

“…The change in the color intensity, or optical density, is measured using a radiachromic reader, or simple spectrophotometer. The radiachromic films used at the APS have a linear response to ionizing radiation over a dose range of approximately 0.1 Mrad to 20 Mrad [12,15,16]. They have an equivalent response to x-rays, γ-rays, and electrons from ultraviolet energies up to approximately 10 MeV [17,18,19].…”
