Interim report: The Fukushima disaster has not harmed health

Reference: News, 29. May 2012

Keywords: Fukushima, health, harmful fallouts

Abstract: “New Scientist” reports: already more than a year has passed since the Fukushima disaster, so it is possible to make a report on the effect of fallouts on people’s health. According to the specialist, there is no need to consider unfavorable consequences, since the quantity of radioactive fallouts is much less than the same of Chernobyl. The exposure level of children, affected by the Fukushima disaster, is 10 times less than those of Chernobyl.

Then water is poured into the gap and the electric arc is ignited. The high temperature, caused by the arc, melts the metallic surface. Under the force of the electro-shock, occurs a quenching of the discharge, wherein the molten metal is ejected out of the hole and granulated in cold water.
