The Fukushima Daiichi nuclear power plant will start releasing treated and diluted radioactive wastewater into the Pacific Ocean as early as Thursday — a controversial step that the government ...
Tokyo Electric Power Company (Tepco) started releasing on Thursday more treated radioactive water from Japan's wrecked Fukushima Daiichi nuclear power plant, as part of a plan that has caused ...
Highly radioactive water leaked from a treatment machine at the tsunami-hit Fukushima Daiichi nuclear power plant, but no one was injured and radiation monitoring shows no impact to the outside ...
About 60 tanker trucks have been filled with filtered water to remove radioactive contamination from the K West Reactor basin as it is being drained. The work will protect the nearby Columbia River.
Caesium-137 concentration in the air, 19 March 2011. Radioactive materials were dispersed into the atmosphere immediately after the disaster and account for most of all such materials leaked into the environment. 80% of the initial atmospheric release eventually deposited over rivers and the Pacific Ocean, according to a UNSCEAR report in 2020.

A recent report on the Sava river in Serbia suggests that many of the river silts contain about 100 Bq kg −1 of natural radioisotopes (226 Ra, 232 Th, and 238 U). [2] According to the United Nations the normal concentration of uranium in soil ranges between 300 μg kg −1 and 11.7 mg kg −1 . [ 3 ]
RTGs are still a potential source of radioactive contamination: if the container holding the fuel leaks, the radioactive material will contaminate the environment. The main concern is that if an accident were to occur during launch or a subsequent passage of a spacecraft close to Earth, harmful material could be released into the atmosphere.
After months of controversy and anticipation, Japan is set to begin releasing treated radioactive wastewater from its Fukushima nuclear plant later this week despite fierce objections from some ...
