Preliminary comments, CRIIRAD mission in Japan from May 24th to June 3rd, 2011:


[Emphasis Added]


[…] During TEPCO’s press conference of May 30th, the CRIIRAD laboratory manager, Mr Chareyron, asked a TEPCO representative about the air contamination monitoring procedure in the vicinity of Fukushima Daiichi. TEPCO explained that there was only one monitoring station, located at the western gate, but stated that the device is used only about 20 minutes each day. This means that during the remaining 98,6 % of the time, the contamination of the air around the plant is not measured. The CRIIRAD wondered how it is be possible when a small NGO such as the CRIIRAD is able to run 5 air monitoring stations in France, that TEPCO could not afford one. TEPCO replied that it was not a money issue but a lack of personnel qualified to change the filters of the instruments.

In the same building belonging to the Fukushima prefecture, the CRIIRAD met with an officer in charge of emergency situations. The CRIIRAD asked about the type of measurement that was implemented to detect early increases of air contamination. The officer said that the air dose monitor located in Fukushima city was no longer operational due to contamination by the accident and that a network of air samplers were measuring air contamination in the vicinity of the nuclear plant. He explained that these devices are not automatically operated but instead manually operated by people who have to physically go there and change the filters. Unfortunately, this is done in such a way, that the measurements are done only during 15 to 20 minutes each day. […]
