Description / Abstract:
This guide covers procedures for using radiationsensitive
indicators (referred to hereafter as indicators) in radiation
processing. These indicators may be labels, papers, inks or
packaging materials which undergo a visual change when exposed to
ionizing radiation (1-5).2
The purpose for using indicators is to determine visually
whether or not a product has been irradiated, rather than to
measure different dose levels.
Indicators are not dosimeters and shall not be used as a
substitute for proper dosimetry. Information about dosimetry
systems for radiation processing is provided in other ASTM and
ISO/ASTM documents (see ISO/ASTM Guide 51261).
This standard does not purport to address all of the safety
concerns, if any, associated with its use. It is the responsibility
of the user of this standard to establish appropriate safety and
health practices and determine the applicability of regulatory
limitations prior to use.
