Full Description

ISO 4037-1:2019 specifies the characteristics and production methods of X and gamma reference radiation for calibrating protection-level dosemeters and doserate meters with respect to the phantom related operational quantities of the International Commission on Radiation Units and Measurements (ICRU)[5]. The lowest air kerma rate for which this standard is applicable is 1 Gy h?1. Below this air kerma rate the (natural) background radiation needs special consideration and this is not included in this document.
