Abstract
ISO/ASTM 51539 covers the use of radiation-sensitive indicators in radiation processing. These indicators may be labels, papers, inks or packaging materials which undergo a colour change or become coloured when exposed to ionizing radiation.
The purpose of these indicators is to determine visually whether or not a product has been irradiated, rather than to measure different dose levels.
