Remarks:
This CRM was prepared from brown rice grains. The brown rice grain of 81.00 g was sealed with a height of 5 cm in a polypropylene container (with an outside diameter of 55 mm and a height of 55 mm). And the container was sealed in an aluminum-coated bag. This CRM should be stored at a temperature between 5 °C and 35 °C in a clean place and shielded from light.

Intended Use:
This CRM is intended for use in controlling the precision of analyses and validating analytical methods and instruments used for determination of 134Cs and 137Cs in brown rice and rice.

Remarks:
Environment and Climate Change Canada matrix reference materials (RMs) are collected in bulk from various locations across North America. PERADE-17 was collected from the Ste Anne River in Quebec in September 2016. The bulk sample was pre filtered to remove particulates and filtered through a 0.2 µm sterilizing filter to remove bacteria. This bulk Major Ions and Nutrients in water RM is stored in a dark cold room and is unpreserved.

Intended Use:
This Reference Material is intended for the verification or development of analytical methods for environmental analysis. It is not intended for use as a calibration standard.
