A versatile radiochromic dosimeter for low‐medium gamma radiation and its application to food irradiation

Abstract: This article presents a novel radiochromic film for selective detection of low-medium (0-10 kGy) gamma radiation ( 60 Co) doses. This dosimeter is based on a printed fluorescent multilayer structure comprising a paper substrate having layers of copper phthalocyanine (DY220) (a green emitter material) on the bottom, and layers of poly[2-methoxy-5(2 0 -ethylhexyloxy)-p-phenylenevinylene] (MEH-PPV) (a green-light absorber, red emitter, and radiation sensitive polymer) on the top. The effect of gamma radiation on … Show more
