Can iodized salt be used to help counter any radiation exposure?

I heard that many people gather iodized salt to prevent counter effect of any radiation exposure with the fear of Japanese nuclear crisis. But in order to achieve WHO recommended  dosage people will need to intake 80 tablespoons would be needed to equal one tablet which is not practical and healthy. So I think it is only myth of people to try iodized salt. In many cities in counties around Japan, there are salt shortage as people try to prevent them with iodized salt. But I think this is not a practical solution as it is not possible to intake required potassium iodide amount iodized salt.

Potassium iodide tablets to help counter effects of potential radioactivity Japan's reactors

Today BBC report that Potassium iodide tablets were distributed among some US crops to prevent counter effects of potential radioactivity Japan's reactors. And it is heard that people all over the world searching for this tablet for help counter effects of potential radioactivity Japan's reactors.

I search about this tablets and found that in 1982 US FDA has approved this tablet for protect thyroid glands from radioactive iodine involving accidents or fission emergencies.

For more details please visit Wikipedia page 

I heard that people try to use iodized salt to get Potassium iodide to fight against potential threats but unfortunately it is only a myth as you need to take approximately 80 spoons to equal sufficient amount.

Staff to be evacuated from Fukushima Daiichi nuclear plant

After new fire happen in reactor 4 in Fukushima Daiichi nuclear plant radiation level on the site has raised   up to health risky level of the employees and they are force to evacuated from the plant. Japan already confirmed to  ask the US military for help in battling the crisis.

New earthquake hits Tokyo Japan

BBC updates a New earthquake hits Tokyo Japan and twitter updates says it pretty decent this time. I feel very sorry for people in Japan who already suffering.

Update: Several friend in Tokyo confirmed that they feel slight earthquake now. (While i am writing this blog post)

Lessons to learn from Fukushima Daiichi nuclear power plant disaster

globalvoicesonline.org



We had two main tragedies in Nuclear power industry; one in Chernobyl and other in Three Mile Island. I am sure, all nuclear experts around the world took these case studies to tighten their safety precautions. Now we have another disaster @ Fukushima Daiichi nuclear power plant, Japan. However, this new accident widen up our angle to see the safety of nuclear power plants.  Analysis says failure of cooling systems after automatic shutdown @ 8.9 earthquake was the main cause behind series of blast in Fukushima Daiichi nuclear power plant. As Japan is frequently subjected to earthquakes and tsunamis they might tighten their safety procedures for natural disasters. However the level of the impact of 8.9 earthquake might be very high than what they expected when they design and commissioning  Fukushima Daiichi nuclear power plant.

I think we must taken following factors in future discussions of nuclear safety

  1. 1.       Nuclear plants safety at natural disasters
  2. 2.       Shutting down procedures at natural disasters
  3. 3.       Effects on people who already affected by natural disaster (people without communication tools, transportation, … )
  4. 4.       Information management in emergency situation  
  5. 5.       Effects on wind patterns at emergency situation

Explosion at Fukushima Nuclear Power Plant (Video)

 (Picture source BBC News)


A Massive Explosion occurred  at Fukushima Nuclear Power Plant and we can see video of the blast on BBC. Several workers injured and experts measures the radioactive level of the site. This is third incident after Three Mile Island in the US in 1979, and Chernobyl in Ukraine in 1986. Definitely this accident will goes to history of Nuclear accident and even for industrial accident.

Due to safety procedures of nuclear power plant it was automatically shutdown after earth quake hits Fukushima. But one of cooling system of reactor was damaged and did not worked accordingly after the shutdown. This tends to meltdown one of reactor.

Download white paper on Failure Rates and Temperature Effects of Photovoltaic Modules



Photovoltaic modules are needed to design to meet the reliability and safety requirements of national and international test standards or company internal quality standards. Qualification testing is a short-duration which last long typically, 60-90 days accelerated testing protocol, and it may be considered as a minimum requirement to undertake reliability testing. This white paper will give you wide exposure on Failure Rates and Temperature Effects Photovoltaic Modules.
