On Wednesday TEPCO sent 6 workers into Fukushima Daiichi Units 2 and 3 to inspect the areas around the suppression chamber for the first time. Pipes littered the ground, and workers were careful to measure the radiation levels prior to entering a new area inside the wrecked building. The lower levels were confirmed to still be flooded with contaminated radioactive water, which is having a visible effect on the metal stairs and railing.
NHK reported the degree of clearness was 5m, but all the other important information,such as the radiation level, temperature, nuclides, the state of the pool were not reported.

Compared to Chernobyl, the Fukushima plant clean up seems to be doing well.
The video in the OP is only a prediction based on mathematical models. Not an actual map of the plume.
I wonder if the moby-duck scenario could be of help here...
en.wikipedia.org...
Moby-Duck: The True Story of 28,800 Bath Toys Lost at Sea and of the Beachcombers, Oceanographers, Environmentalists, and Fools, Including the Author, Who Went in Search of Them is a book by Donovan Hohn concerning 28,800 plastic ducks and other toys, known as the Friendly Floatees, which were washed overboard from a container ship in the Pacific Ocean on 10 January 1992 and have subsequently been found on beaches around the world and used by oceanographers including Curtis Ebbesmeyer to trace ocean currents.
I hope you're right but you contridict your own post. The "Moby Ducks" ended up on beaches all over the planet.

Again, the casualty figures tell their own story. Severe potential hazards did exist on the reactor sites because of high levels of radiation, but health controls were mainly effective.
There were no deaths attributable to radiation. Two workers received burns from beta radiation. They were discharged from hospital after two days. Two workers incurred high internal radiation exposure from inhaling iodine-131, which gives them a significant risk of developing thyroid cancer.
Doses incurred by about 100 other workers have been high enough to cause a small risk of developing cancer after 20 or more years. But the risk is very small indeed. About 25 per cent of the population dies from cancer whether accidentally exposed to radiation or not. This rate might be increased by an additional one or two per cent among the exposed workers.
What is more, exposures to radiation were nowhere near high enough to cause acute radiation sickness. Importantly, there have been no radiation injuries to children or to other members of the public. The INES was intended to aid public understanding of nuclear safety. In fact, it has caused more confusion. It has also probably added to the mental anguish of the Japanese people.
The accident at Fukushima Daiichi was moved to the top of the scale a month after the tsunami for technical reasons, when the estimate of radioactive material released exceeded the International Atomic Energy Agency's criterion for level 7. However, the amount of iodine-131 escaping from all the reactors at Fukushima Daiichi was less than 10 per cent of the amount released at Chernobyl, and the release of caesium-137, the next most important fission product, was less than 15 per cent of the Chernobyl total.
