The News That Matters about the Nuclear Industry

Simple Error or Calculated Revisionism?

From Majia’s Blog
I was reading a Mainichi news story this morning on airborne radiation levels near Fukushima Daiichi, which remain quite elevated.

What struck me about the reported story is the assertion that the government set the radiation exposure level at 1 millisievert a year after the accident:

Airborne Radiation Near Fukushima Nuke Plant Still Far Higher Than Gov’t Max. (Jan 18, 2018) The Mainichi https://mainichi.jp/english/articles/20180118/p2a/00m/0na/020000c

Following the March 2011 triple meltdown, the government set a long-term radiation exposure limit of 1 millisievert per year, which breaks down to an hourly airborne radiation dose of 0.23 microsieverts.  The NRA took airborne radiation readings in the Fukushima Prefecture towns of Futaba, Okuma, Namie and Tomioka, and the village of Katsurao. The highest reading registered in the previous year’s survey was 8.89 microsieverts per hour, in Katsurao.

What I find confusing and disconcerting is the fact that the government set the radiation level after the accident at 20 millisieverts a year, not 1.

Was a simple error involved in the reporting here? Or is revisionism under way?

One way I’ve seen propaganda operate over the last five years is for an untruth to be planted and repeated over and over again until it becomes part of the public record as a “truth.”

Yet, the 20 millisievert a year limit has circulated widely in the media as well and will be difficult to replace (e.g., see here https://theconversation.com/acceptable-risk-is-a-better-way-to-think-about-radiation-exposure-in-fukushima-56190).

Was this an error or is it something else entirely?
