Researchers from RIKEN Report Recent Findings in Risk Management (Sample Size Allocation for Food Item Radiation Monitoring and Safety Inspection)

By a News Reporter-Staff News Editor at Insurance Weekly News -- Investigators publish new report on Risk Management. According to news reporting originating from Saitama, Japan, by VerticalNews correspondents, research stated, "The objective of this study is to identify a procedure for determining sample size allocation for food radiation inspections of more than one food item to minimize the potential risk to consumers of internal radiation exposure. We consider a simplified case of food radiation monitoring and safety inspection in which a risk manager is required to monitor two food items, milk and spinach, in a contaminated area."

Our news editors obtained a quote from the research from RIKEN, "Three protocols for food radiation monitoring with different sample size allocations were assessed by simulating random sampling and inspections of milk and spinach in a conceptual monitoring site. Distributions of I-131 and radiocesium concentrations were determined in reference to I-131 and radiocesium concentrations detected in Fukushima prefecture, Japan, for March and April 2011."

According to the news editors, the research concluded: "The results of the simulations suggested that a protocol that allocates sample size to milk and spinach based on the estimation of I-131 and radiocesium concentrations using the apparent decay rate constants sequentially calculated from past monitoring data can most effectively minimize the potential risks of internal radiation exposure."
