In Topic: Fukushima Radioactive Ocean Impact Map

16 March 2012 - 06:10 PM

Hi guys,

I don't know if this is accurate, but if it is, is very alarming.

Fukushima Radioactive Ocean Impact Map - March 2012 Update

Does anybody has more information about this?


This is not accurate at all. This is based solely on drift models. There are water monitors right offshore the power plant that constantly test the water and the fish showing levels well below anything considered unsafe.

Theres's no good data regarding the initially amount released (source) and no good data regarding the concentrations of the type of contamination (Iodine vs cesium's uranium) Additionally the Iodine isotopes break down very quickly (matter of weeks) and most of the contamination was iodine related (but some cesium and uranium was detected). This drift model cannot account for these factors (especially that iodine isotopes have a half life of ~8days)

do not put stock in this graphic, it's not based on enough facts to accurately represent the situation.

Thanks,
john

I've begun to get worried about you guys so I've added a picture of something I am drooling over at the moment for reasons of bringing back some sanity.


Does it come with a 45 deg viewfinder?????????
