The radiation from the Fukushima nuclear power plant failure in Japan has turned out to be less of a problem than predicted.

The radiation from the Fukushima nuclear power plant failure in Japan has turned out to be less of a problem than predicted.

[O]utside the immediate area of Fukushima, this is hardly a problem at all. Although the crippled nuclear reactors themselves still pose a danger, no one, including personnel who worked in the buildings, died from radiation exposure. Most experts agree that future health risks from the released radiation, notably radioactive iodine-131 and cesiums-134 and – 137, are extremely small and likely to be undetectable. Even considering the upper boundary of estimated effects, there is unlikely to be any detectable increase in cancers in Japan, Asia or the world except close to the facility, according to a World Health Organization report. There will almost certainly be no increase in birth defects or genetic abnormalities from radiation.

Even in the most contaminated areas, any increase in cancer risk will be small. For example, a male exposed at age 1 has his lifetime cancer risk increase from 43 percent to 44 percent. Those exposed at 10 or 20 face even smaller increases in risk — similar to what comes from having a whole-body computer tomography scan or living for 12 to 25 years in Denver amid background radiation in the Rocky Mountains.

The entire article is worth reading, as it outlines in detail the less than deadly consequences of both Fukushima and Chernobyl. This is the kind of information we should use to rationally decide whether we want to build more nuclear power planets.

While thousands protest the restarting of any nuclear power plants in Japan following last year’s earthquake, some scientists have questions about one particular plant.

The article’s headline falsely suggests that the scientists oppose all nuclear power plants, which is not the case. If anything, the overall manner in which the Fukushima power plant withstood the biggest earthquake in history demonstrated that most of Japan’s nuclear power plants are probably safe from future earthquakes. For scientists to have concerns about one particular plant seems reasonable, however, and is not the same thing as opposing all nuclear power.

The radiation released from the Fukushima nuclear power meltdown in Japan last year will cause almost no cases of cancer according to two separate reports.

This story is almost a week old. I missed it initially because Nature buried the results, headlining the story in the most boring way possible: “Fukushima’s doses tallied”.

These results however illustrate again the success of the engineering at the nuclear power plant. Certainly they did things wrong, and certainly there were engineering failures there. Nonetheless, the safety features allowed them to contain the power plant even after it experienced the most powerful earthquake in recorded history followed by the most powerful tsunami in a thousand years.

It appears that the floating debris from the earthquake and tsunami in Japan last year is reaching North America sooner than expected.

I got a laugh from the last two sentences of this story. The early arrival of “more than 200 bottles, cans, buoys and floats” from Japan was immediately turned into a crisis that required government intervention.

With debris making landfall sooner than predicted, U.S. lawmakers have started to question whether the government is truly prepared. “Many people said we wouldn’t see any of this impact until 2013 or 2014, and now ships and motorcycles and this various debris is showing up and people want answers,” U.S. Sen. Maria Cantwell, D-Wash., said.

And if the debris was taking longer to get here? Cantwell would then argue we need to spend more money to track it more precisely. By her standards, no matter what happens, government has got to get bigger.

At a conference in Washington DC yesterday both Russia and Japan announced the Moon as their next primary space exploration goal.

If the U.S. gets a competitive private aerospace industry going — which seems increasingly likely — I’m willing to bet those companies will get to the Moon before either of these governments.

New simulations suggest that the magnitude of tsunamis predicted to hit Japan have previously been underestimated.

New simulations suggest that the magnitude of tsunamis predicted to hit Japan have been significantly underestimated.

The difficulty here is that these predicted giant tsunamis are still expected to be very rare events. It is thus unclear what is more practical, to build things at great cost so that they can survive these rare events, or to live with the risk and rebuild each time after disaster strikes.

A Thank You From Japan

One year ago today Japan was hit with one of the most powerful earthquakes in recorded history, followed almost immediately by one of the most powerful tsunamis in recorded history. Since then, that nation and its people have done an incredible job recovering from that disaster, proving once again that there really is no limit to what humans can do.

The video below is their thank you to the rest of the world for the help and support brought to Japan by people everywhere. As they say, “Arigato.”

I say, bless you all for never giving up.
