Ruthenium-103 + Ruthenium-106

All foods as prepared for consumption

Additional information on how a commodity is defined and how the level is applied can be found within the documents linked to in the Reference data field.
Contaminant: Ruthenium-103 + Ruthenium-106
Commodity: All foods as prepared for consumption
Contaminant Level Type: Derived Intervention Level
Levels: < 1 Bq/kg
Reference†: CPG 555.880
Notes: The equation for calculating adherence to the DIL is (C3 / 6800 ) + ( C6 / 450 ) < 1. Due to the large differences in DILs for Ruthenium-103 and Ruthenium-106, the individual concentrations of Ruthenium-103 and Ruthenium-106 are divided by their respective DILs and then summed. The DIL for the Ruthenium group is set at less than one. C3 and C6 are the concentrations, at the time of measurement, for Ruthenium-103 and Ruthenium-106, respectively.
