Japan: Damaged Nuclear Plant Released More Radioactive Material Than Previously Estimated; Thousands Call for Nuclear Moratorium

Japan: Damaged Nuclear Plant Released More Radioactive Material Than Previously Estimated; Thousands Call for Nuclear Moratorium.

Democracy Now!

Newly released data from the Japanese government indicates radioactive material was leaking into the atmosphere from the Fukushima Daiichi nuclear power plant Number 1 Unit in far greater quantities than previously estimated. The Daily Yomiuri newspaper reports the level of radiation on April 5 was six times higher than initially reported. In other news from Japan, 25,000 Japanese soldiers are being sent into the disaster zone to scour for the bodies of nearly 12,000 people missing and presumed dead. The estimated death toll from the tsunami and earthquake is 26,000. On Sunday, thousands of people rallied in Tokyo to call for the closure of all nuclear power plants in Japan. 

Atmospheric radiation leak underestimated

(japanese Article)

On April 17, plant operator Tokyo Electric Power Co. said in its plan for stabilization of the crippled reactors it would not start to get radiation leakage under control until the plan’s fourth month of implementation.

This would mean 10,000 terabecquerels of radioactive substances would be released into the atmosphere from the plant during the coming three months, according to simple calculations based on the estimated emission rate as of April 5…

The total amount of radioactive material discharged from the plant from March 11 to early April was estimated between 370,000 and 630,000 terabecquerels, according to government sources.

terabecquerel equals 1 trillion becquerels, a measure for radiation emissions…a measurement in becquerels is proportional to activity, and thus a more dangerous source of radiation gives a higher reading…One Becquerel is defined as the activity of a quantity of radioactive material in which one nucleus decays per second…so I guess 1 terabecquerel is radioactive material in which one nucleus decays per 11,574 days or every 31 years??? If my math and understanding is correct. – VT4Evolution
