Japan to raise worker emergency radiation exposure limits

21 May 2015

Japan's nuclear regulator is to increase the radiation exposure limit for workers in emergency situations from the current 100 millisieverts (mSv) to 250 mSv. The limit was temporarily raised following the March 2011 accident at the Fukushima Daiichi plant.

Normally nuclear workers are allowed to receive a dose of 20 mSv per year, although in practice they often receive very much less. In emergency circumstances, safety regulators allow workers to receive up to 100 mSv.

Japan's Nuclear Regulation Authority said in a statement today that it will increase the emergency exposure limit to 250 mSv from April 2016.

Making room for nature

The Ecomodernist Manifesto is positive, science-based, technologically upbeat and realistic in facing up to the expectations of 7+ billion people. And it isn't over the top, writes Ian Hore-Lacy.

The document was published on 14 April over the names of 18 individuals known for their environmental stance and writings. Mark Lynas, Michael Shellenberger, Linus Blomqvist, Ted Nordhaus and Stewart Brand are possibly the best-known internationally, along with Australia's Barry Brook, and filmmaker Robert Stone.

They wrote: "We affirm one long-standing environmental ideal, that humanity must shrink its impacts on the environment to make more room for nature, while we reject another, that human societies must harmonize with nature to avoid economic and ecological collapse."
