Water at Fukushima nuclear plant still radioactive

Tokyo Electric Power Co. (TEPCO) has revealed that much of the water stored at the disaster-stricken nuclear plant – that the Japanese government was considering releasing into the Pacific Ocean – is still radioactive. This disturbing admission has indeed complicated the on-going decommissioning process, which is already marred by a number of other factors.

The Discovery of Cesium Rich Microparticles

The 2011 Fukushima nuclear disaster was the second-most serious nuclear accident in history, after Chernobyl in 1986. It caused serious damage to the nuclear reactors 1, 2, 3 and 4 at the Fukushima Daiichi Nuclear Power Plant. As a result, massive amounts of radionuclides were released in Fukushima prefecture, posing serious environmental threats of known, and unknown, nature.

How ionizing radiation affects the body

When we talk about radiation exposure and its effects on the body, we usually mean ionizing radiation (IR) – the kind that can damage living tissue. The fact is, we are exposed to ionizing radiation every day either from natural sources (coming from radon, minerals, rocks, soil, and cosmic rays) or from man-made sources (from exposure to X rays, CT scans, radiotherapy, nuclear accidents and workplace radiation).

Radiation Effects on Fukushima Monkeys

The radioactive material injected into the environment by the 2011 Fukushima accident, the world’s second largest nuclear disaster after Chernobyl, has led to widespread consequences on human health. Studies tell us that this radioactivity is going to persist in the environment for a long time and highlight that there is no safe dose below which there are no side effects.

Fukushima-borne Cesium-137 to contaminate food supply for decades

It’s been almost eight years since a major earthquake and the resulting 15-metre tsunami caused a severe nuclear accident at Japan’s Fukushima Daiichi Nuclear Power Station. The fuel meltdown and subsequent explosion released massive amounts of radioactive material into the environment – including iodine-131, cesium-134 and cesium-137 (Cs-137) – heavily contaminating the Pacific Ocean.
