(CNN) -- An explosion has been reported at a nuclear plant in northeastern Japan's Fukushima prefecture, Japanese public broadcaster NHK said Saturday, citing the country's nuclear and industrial safety agency.

The Tokyo Electric Company said four workers on the ground were injured, NHK reported.

It was not immediately clear where the blast occurred at the Fukushima Daiichi plant, or what caused it.

NHK said the injured workers were in the process of cooling a nuclear reactor at the plant by injecting water into its core.

Earlier Saturday Japan's nuclear agency said workers were continuing efforts to cool fuel rods at the plant after a small amount of radioactive material escaped into the air.

The agency said there was a strong possibility that the radioactive cesium monitors detected was caused by the melting of a fuel rod at the plant, adding that engineers were continuing to cool the fuel rods by pumping water around them.

A spokesman for Japan's Nuclear and Industrial Agency earlier said atomic material had seeped out of one of the five nuclear reactors at the Daiichi plant, located about 160 miles (260 kilometers) north of Tokyo.

Authorities evacuated people living near the reactor after an earthquake and tsunami crippled cooling systems there, as well as at another of the Tokyo Electric Power Company's nuclear plants.

The evacuations notwithstanding, the nuclear safety agency asserted Saturday that the radiatio... >>>

May be a little to worry!

 Mr.Rahmanian

There is some danger  if there is an  exposure to I-131, that can be  absorbed by the lungs and then in form of mucus will be introduced to digestive system( or to be ingested by mean of mucus).I-131 if

ingested the first place knows to go is the Thyroid gland and then can become harmful.

Usually I-131 is released after the 4 defense layer desgined to

protect the reacotr core and public called D.I.D has failed.

DID  or defense in depth has 4 layers, fuel cladding, reactor vessel,

containment and emergency cooling system.

The reactor vessel is desinged to hold up to 2500 psi and the

containment design is 50 psi but can hold up to 100 psi.

The Japan news said the roof of the containment is gone, that means there was enough I-131 which is gaseous form and some other gaseous form element has exceeded the 50 and even 100 psi

and those gases were introduced to the enviroment.

cheers

We'll Meet Again - Vera Lynn

by Darius Kadivar on Sat Mar 12, 2011 03:02 AM PST


 Let's say goodbye with a smile dear, 
Just for awhile dear, we must part 
Don't let this parting upset you, 
I'll not forget you, sweetheart, 

We'll meet again, 
Don't know where,don't know when. 
But I know we'll meet again, some sunny day. 

Keep smiling through , 
Just like you always do, 
Till the blue skies chase those dark clouds, far away. 

And I will just say hello, 
To the folks that you know, 
Tell them you won't be long, 
They'll be happy to know that as I saw you go 
You were singing this song .
