The source explained that the move is part of concerns about the spilling of treated radioactive water from the Fukushima nuclear power plant in Japan into the ocean.

The hyperpure germanium detectors, also known as HPGe gamma ray spectroscopy, are a precision device that checks the radiation levels of a product, for three hours.

The government explained these new devices are in addition to existing rapid testers, which take one hour to test for radiation.

The city also plans to set up a laboratory for comprehensive radiation inspection, equipped with a pretreatment facility; and will hire more professionals to ensure food safety.

According to authorities, professional inspectors will check the radiation level of randomly taken seafood samples and request the Seoul Public Health Research Institute to conduct a re-examination in case of suspected excessive radiation.
