Low doses release from Fukushima?.. bollocks.. Tepco released on 12/27/2012, 10 million Bq of cesium-134/1


According to mid/long term roadmap of Tepco released on 12/27/2012, 10 million Bq of cesium-134/137 is still released from reactor1, 2 and 3 every single hour.

This is measured at the top part of each reactor building. The amount is computed from the dust density of Cs-134/137, other nuclides are excluded.

Since this April, the releasing amount has been stably around 10 million Bq / hour.

every single hour..... every single hour.....

166 666.666~ Bq/per minute.......

100 per year normal dose... per year....
 
Caesium (Cs) has 40 known isotopes. The atomic masses of these isotopes range from 112 to 151. Only one isotope, 133Cs, is stable. The longest-lived radioisotopes are 135Cs with a half-life of 2.3 million years, 137Cs with a half-life of 30.1671 years and 134Cs with a half-life of 2.0652 years. All other isotopes have half-lives less than 2 weeks, most under an hour.
Beginning in 1945 with the commencement of nuclear testing, caesium isotopes were released into the atmosphere where it is absorbed readily into solution and is returned to the surface of the earth as a component of radioactive fallout. Once caesium enters the ground water, it is deposited on soil surfaces and removed from the landscape primarily by particle transport. As a result, the input function of these isotopes can be estimated as a function of time.
