Japanese plant operator Tokyo Electric Power Company (TEPCO) studied a black rockfish in May and found that it contained levels of radioactive cesium that were 180 times over Japan’s regulatory limit.
The radioactive fish was caught near drainage outlets at the TEPCO plant, where three nuclear reactors melted down amidst a tsunami in March 2011. Rainwater from areas near the reactors flows into the area where the fish was caught.
The alarming discovery reignited concerns over TEPCO’s plans to start releasing 1.3 million tons of treated wastewater from the former Fukushima Daiichi nuclear power plant by August.
A report from July 23 showed that the problem is still unaddressed, prompting questions about how dangerous the company’s plans are for the public.
Radioactive cesium health risks
Radioactive cesium has been detected in surface water and different kinds of food, such as breast milk and pasteurized milk. The amount of radioactive cesium in food and milk depends on several factors.
The most important factor is whether or not there has been a recent fallout from a nuclear explosion, like a weapons test or an accident at a nuclear power plant.
