Iodine advice for children dosage

Thu, 2011-03-24 16:38 — AlMac99

IAEA PDF 19 March (attached) reports that on 16 March, Japan's Nuclear Safety Commission recommended local authorities to instruct evacuees leaving the 20-kilometre area to ingest stable (not radioactive) iodine. The pills and syrup (for children) had been prepositioned at evacuation centers. The order recommended taking a single dose, with an amount dependent on age:
Baby 12.5 mg
1 mo.-3 yrs. 25mg
3-13 yrs. 38mg
13-40 yrs. 76mg
40+ yrs. Not necessary

News Media declared war against truth and against the victims of disaster

Thu, 2011-03-24 16:02 — AlMac99

People's lives are on the line, as there are efforts to rush aid to vulnerable members of society. Some aid is seriously delayed due to bogus stories about the radiation risks.

Public policy is expensive, especially when it comes to figuring out how to be better prepared against similar disasters.  I am also seeing how Japanese imports are being blocked at foreign borders, thanks to misinformation about radiation.

News media should endeavor to report the truth, to help the helpers who seek to get relief aid to the vulnerable.

But instead, the news media is on a science fiction fantasy trip, describing their worst nightmares as pure speculation. People on the USA west coast are tooling up to protect against radiation coming across the Pacific from Japan, and I have seen lots of lovely maps speculating the path of this radiation, but it is all a fiction.  The only radiation risk so far, is inside the evacuation zone, and trivial rainfall contamination, where Japan tracing where that happening.

International Nuclear and Radiological Event Scale (INES)

INES – The International Nuclear and Radiological Event Scale

 What is INES?

INES - is a tool for promptly communicating to the public in consistent terms the safety significance of reported nuclear and radiological incidents and accidents, excluding naturally occurring phenomena such as Radon. The scale can be applied to any event associated with nuclear facilities, as well as the transport, storage and use of radioactive material and radiation sources.

Description - Construction of Fukushima Nuclear Power Plants, and Fuel Pellets

Thu, 2011-03-24 14:54 — Kathy Gilbeaux

by Dr. Josef Oehmen of Massachusetts Institute of Technology (MIT)

The plants at Fukushima are Boiling Water Reactors (BWR for short). A BWR produces electricity by boiling water, and spinning a a turbine with that steam. The nuclear fuel heats water, the water boils and creates steam, the steam then drives turbines that create the electricity, and the steam is then cooled and condensed back to water, and the water returns to be heated by the nuclear fuel. The reactor operates at about 285 °C.

NISA = Japan’s Nuclear and Industrial Safety Agency - thru Mar 18

Thu, 2011-03-24 06:26 — AlMac99

I shared some earlier reports - thru March 15 - here.  I continue to work my way thru the Japan reports from the horse's mouth, and attached are NISA reports March 16 17 18.  I will share more as I get thru more. 

Here, from my notes, are my sources of this information.

Date at beginning of sub-head is vintage of the official information.

Date in parentheses at end of each sub-head is when I got my hands on the info.


U.S.: Nuclear Safety Task Force To Be Formed

Wed, 2011-03-23 23:49 — Kathy Gilbeaux

March 23, 2011

The U.S. Nuclear Regulatory Commission will set up a task force to review nuclear plant safety, according to a statement released by the commission March 23. The task force will be made up of former senior managers and former agency experts to analyze lessons from the nuclear disaster in Japan. Each plant will send representatives to participate in the task force’s work, which will be released to the public, according to the commission.
