Radioactively-Hot Particles in Japan; New Study Shows Full Radiation Risks are not Recorded

The article details the analysis of radioactively hot particles collected in Japan following the Fukushima Dai-ichi meltdowns. Based on 415 samples of radioactive dust from Japan, the USA, and Canada, the study identified a statistically meaningful number of samples that were considerably more radioactive than current radiation models anticipated. If ingested, these more radioactive particles increase the risk of suffering a future health problem…

Fukushima city is going to host Olympic baseball and softball games in 2020.
What is the level of radio-contamination there? This is the question on everybody’s mind, spectators and players from all over the world. Is it really safe?

Baseball and softball games will take place in Azuma Sports Park in Fukushima city.

Fukushima prefecture provides the information below on the radiation measurements of the Park.

4Measurements of the airborne radiation dose in the baseball stadium: No 13-16
Those of the softball stadium: No 4
The lines above and below indicate the value of the radiation dose at 1cm and 5cm above the ground.

We notice that, as usual, Fukushima prefecture gives only measurements in terms of radiation dose. Based on this information, one might think that it would be relatively safe to play there or to attend the games. However, monitoring only the radiation dose is not enough for…

31 july 2017.jpg

A government advisory body has compiled a draft blueprint for recovering nuclear fuel debris  from the No. 1 to 3 reactors that melted down at Tokyo Electric Power Company Holdings Inc.’s Fukushima No. 1 power plant, it has been learned.

According to the draft from the Nuclear Damage Compensation and Decommissioning Facilitation Corporation, the recovery project will prioritize collection of debris that has piled up at the bottom of the reactors, installing a robot arm into the reactor containment vessels from the side and controlling it remotely as its main operation.

The aim is to start the project in 2021. All the decommissioning work is expected to be completed sometime from 30 to 40 years after the disaster occurred.

The draft was presented Monday at an expert panel meeting held by the Economy, Trade and Industry Ministry in Iwaki, Fukushima Prefecture, to discuss ways to decommission reactors and get rid…
