Reports are being issued saying emitted radiation levels, from Fukushima Daiichi, are going down. At the same time reports are being made about increasing radiation levels in water.
Japan’s Nuclear Safety Commission estimates the amount of radioactive emissions are down at around 1 terabecquerels per hour as of Sunday. They compare that to 154 terabecquerels per day on 05 April. But they are talking about emissions into the air.
Tokyo Electric Power Company is reporting skyrocketing radiation levels in water coming from Fukushima Daiichi’s damaged reactors. A survey done on 21 April, found an increase of radioactive substances in the flooded basement of Reactor 4’s turbine building.
TEPCo says the levels of cesium-134 and 137 increased about 250 times, compared to last month. Radioactive iodine has also increased.
A possible reason for the decrease in air borne radiation, and an increase in water born radiation, could be due to the amount of water being pumped into the reactors. However, the over all result is not a decrease in radioactive emissions, it’s just shifted from the air to the water.
