Abstract

A continuous on-line beta sensitive water monitor was developed to determine the ⁹⁰Sr activity levels in water after processing at the Fukushima nuclear power plants. The sensitivity required by the customer, 10 Bq kg⁻¹, posed issues for any existing continuous on-line technology. The developed water monitor has maximized the efficiency to beta radiation while minimizing gamma background, and achieves a minimum detectable concentration of 6.3 Bq kg⁻¹ in a 1 h measurement.
