» New machine takes less than 30 minutes to detect strontium 90

New updated equipment that is scheduled to go into operation at the Fukushima No. 1 nuclear power plant in December will detect radioactive strontium 90 in contaminated water in less than 30 minutes, compared to the seven to 10 days it now takes.

The advanced detection equipment was developed as part of a group effort centered on the work of Yoshitaka Takagai, an associate professor of analytical chemistry in the Faculty of Symbiotic Systems Science at Fukushima University. Researchers from PerkinElmer Japan Co., based in Yokohama, were also involved in the research.

The improved technology involved making changes to an analytical device so that it automatically separates strontium 90 in order to analyze it in a shorter period of time.

TEPCO will use the equipment to test rainwater that has accumulated within containment barriers set up around tanks that store radioactive contaminated water.
