SimplyInfo has reported that from Japan to the U.S. and Germany, nuclear evacuation zones are inadequate to deal with real world risks shown by what happened -- and is still happening -- at and around the destroyed Fukushima Daiichi nuclear power plant, even out to great distances. The article reported:

The US plans show an evacuation zone of about 10 miles (16km), half of what Japan has now moved to. The US has also quietly instituted changes in late 2011 to scale back evacuation plans based on some pre-Fukushima calculations now proven by Fukushima to be unrealistic. The NRC revisions to evacuation zones include a number of ideas we know to be not accurate:

—Accidents will develop more slowly than thought. 

Fukushima was drastically faster than the NRC assumes. 15 hours, not multiple days.

—Buildings designed to contain radiation leaks will hold.

Fukushima proved this is not the case as 4 of the reactors failed and now leak radiation in considerable amounts over a year and a half after the disaster.

—Emergency plans will work.

Fukushima left local government lost with no information to act with, prefecture and national government was in chaos and did not make needed information such as radiation and plume data public so people could react appropriately. There were not enough resources to get people out, evacuate hospitals or distribute protective iodine.

—Responders will do their jobs.

In Fukushima private fire department staff refused to be deployed, Tokyo Fire Department insisted on detailed information before they would agree to risk firefighters' safety and even the SDF fled the area multiple times as those on the ground determined conditions to be too dangerous to stay at that time.

—Ninety percent of those told to stay put will obey.

Many in Fukushima fled of their own motivation if they were able to obtain enough information and had the ability. Expecting 90% of people within 10 miles of a nuclear disaster to stay put defies human nature and common sense. Those with the ability will try to leave if they can. Sheltering in place also poses considerable risks beyond radiation exposure. The practice requires sealing up a house and turning off any air conditioning or forced air heating. In certain parts of the US and around the world this could quickly prove deadly during certain times of the year due to extreme temperatures. The NRC and other safety authorities around the world ignore this risk.
