Relevés de radioactivité éfféctués par l’université de Tokyo

Loic Queval, Etudiant à l’université de Tokyo propose de nous transmettre les relevés de taux de radioactivité effectués dans son université…

Je rappelle que les doses de radioactivite dans l’environnement naturel ; 0.1 – 0.3micro Sv/h
Mon résumé : aucune mesure de précaution à envisager pour le moment.

Bonjour Ines,

L’université de Tokyo conduit des mesures des taux de radioactivités sur 3 Campus (Hongo, Komaba, Kashiwa). Je me permet de vous transmettre ces mesures.

To all members of the University of Tokyo
{{1. Environmental Radiological Countermeasures Project}}
As part of university-wide measures against radiation, the University has established
the Environmental Radiological Countermeasures Project Team, as a unified University
entity, in order to tackle the current radioactive-related issue facing Japan.
The Project team will be led by Professor Yoichiro Matsumoto, Executive Vice
President.

Radiation dose rate in natural environments; 0.1 – 0.3micro Sv/h
The value in natural environments varies depending on areas or weather conditions.
Areas around some natural spas or granites rocks could show readings of relatively
higher dose rates even though such areas are a natural environment.

There is no need to take any emergency measures at the moment.
