… like most, you have other fish to fry and cannot think about fukushima any more.

UPDATE at bottom
"… like most, you have other fish to fry and cannot think about Fukushima any more. However, in the middle of an election campaign, maybe it is appropriate to remind our politicians that they have responsibilities to their electors and the public in general.
so, here is my story/questions
1          the nyt (New York Times) just published an interesting article underlining how simulations done all around the world had a clear picture of what was happening and what was going to happen very early in the game.
2          the slides referenced to in the article are attached and they don't take much of a knowledge to figure out, i.e. even a domestic politician at the knowledge level of Mr Harper could understand them,
3          CDC (Centers for Disease Control and Prevention - Canada) still does not provide readings past March 23, but EPA has all the information that may be useful for the area; where is CDC personnel?
thanks for listening"

1   From Far Labs, a Vivid Picture Emerges of Japan Crisis - New York Times

"Thanks to the unfamiliar but sophisticated art of atomic forensics, experts around the world have been able to document the situation vividly. Over decades, they have become very good at illuminating the hidden workings of nuclear power plants from afar, turning scraps of information into detailed analyses."  Snip.....
"..... Robert E. Henry, a developer of the code at Fauske & Associates, an engineering company near Chicago, said that a first sign of major trouble at any reactor was the release of hydrogen — a highly flammable gas that has fueled several large explosions at Fukushima Daiichi. The gas, he said in an interview, indicated that cooling water had fallen low, exposing the hot fuel rods.

The next alarms, Dr. Henry said, centered on various types of radioactivity that signal increasingly high core temperatures and melting."

Crack found in pit for reactor

Japanese officials grappling today to end the world's worst nuclear crisis since Chernobyl were focusing on a crack in a concrete pit that was leaking radiation into the ocean from a crippled reactor.
Tokyo Electric Power Co. said it had found a crack in the pit at its No. 2 reactor in Fukushima, generating readings of 1,000 millisieverts of radiation per hour in the air inside the pit.
"With radiation levels rising in the sea water near the plant, we have been trying to confirm the reason why, and in that context, this could be one source," said Hidehiko Nishiyama, deputy head of the Nuclear and Industrial Safety Agency, on Saturday.
Leakage did not stop even after concrete was poured into the pit, and Tokyo Electric now plans to use waterabsorbent polymer to prevent contaminated water from leaking out into the sea.     Snip

Govt did not reveal high level radiation estimate
It has been learned that the Japanese government withheld the release of computer projections indicating high levels of radioactivity in areas more than 30 kilometers from the troubled Fukushima Daiichi nuclear power plant.

The estimates were made on March 16th following explosions at the plant by an institute commissioned by the government using a computer system called SPEEDI. The system made its projections on the assumption that radioactive substances had been released for 24 hours from midnight on March 14th, based on the available data.

But the government was reluctant to reveal the SPEEDI projections, and did not release them until March 23rd.
The released data showed that higher levels of radioactive substances would flow over areas to the northwest and southwest of the plant.
