The scope of the catastrophe at Japan's Fukushima Daiichi nuclear complex is enormous. Nearby communities have been evacuated. Radioactive particles and water have spread into the ecosystem. The entire global economy is feeling the impact, as businesses are forced to slow or halt production due to a shortage of crucial parts manufactured in the region. 

Here are some of the numbers connected to the nuclear plant disaster:

7.5 million — Number of times over the legal limit for radioactive iodine that was registered in samples of seawater taken on April 2 at the sluice gate of one of the reactors at the Fukushima plant, according to the Tokyo Electric Power Company (TEPCO). Associated Press reported the figure had dropped to 5 million by April 4, with measurements taken further offshore showing levels down to 1,000 times over the legal limit.

4,080 — The level of becquerels per kilogram (a measurement of radioactivity) detected in seawater near the Fukushima plant, Japanese government officials say. The limit for vegetables is 2,000 becquerels per kilogram, say the officials, who will seek to apply this limit to fish.

$5,000 US — Daily danger pay offered by TEPCO to "jumpers," the name given to workers willing to work at damaged Fukushima nuclear plant, according to Reuters.

600 — Number of jumpers (also called "liquidators" or "samurai workers") on duty in the damaged nuclear plant, many of them resigned to the fact they could be ill or even dead within weeks due to the radiation hazards, according to wire reports.

735 — Number of workers the Japanese Red Cross deployed to Fukushima prefecture, working in 95 medical teams.

452,000 — Japanese government estimate of people who have been displaced from their homes and are living in shelters as a result of the earthquake, tsunami and nuclear disaster.

17,000 — Number of homes and buildings destroyed as a result of earthquake and tsunami, according to the United Nations Office for the Coordination of Humanitarian Affairs (OCHA).

1,400 — Number of schools and nurseries scheduled to be tested in the first week of April in Japan because of parental fears of radiation from the Fukushima plant.

20 kilometres — The distance from the nuclear plant to the edge of the no-go evacuation zone established by the government because of leaking radiation.

$240,000 US — Amount of "apology money" TEPCO has offered to each town or city within the mandatory evacuation zone around the Fukushima plant.

80 per cent — The nose-dive suffered by TEPCO's share price since the nuclear disaster.

57 million — Number of litres of contaminated water pooling around the Fukushima nuclear plant, according to Hidehiko Nishiyama, a spokesman for Japan's Nuclear and Industrial Safety Agency.

35 cubic metres — The amount of liquid waste that can be processed in a day by the Landysh, a Russian floating radiation treatment plant that Japan has asked to borrow, according to the BBC.

$95 million US — Amount donated bilaterally to the relief effort in Japan, according to OCHA.

$309 billion US — What Japan estimates it will cost to rebuild the country in the wake of the earthquake, tsunami and nuclear plant problems.
