摘要： A color-change dosimeter film made of a halogen-containing polymer in which is dispersed an acid-sensitive leuco dye, which dye a) is substantially free from groups that are sensitive to high-energy radiation and b) becomes colored in acid. This color-change dosimeter film (1) remains substantially colorless upon exposure to artificial illumination, including fluorescent light, for at least several months, (2) becomes colored upon exposure to high-energy radiation and accurately indicates small changes in dosage by the intensity of its color, and (3) remains substantially unchanged in its intensity of that color after being stored for several months, whether or not exposed to artificial illumination. An article of either quantitative or qualitative determination of the extent of high-energy radiation exposure is also provided, displaying a colored message of words, codes, symbols, or patterns on a substrate after exposure to the high-energy radiation.
