Harmful effects of Fluoride , page 1

In support of the effort to remove flouride from drinking water, I wanted to share with you my well-founded theory on why male astronauts are coming back from space flights with brain damage and eventual blindness, whereas female pilots are largely unaffected. I wanted to point out that due to menstruation, women deposit far less iron in the body. Men on the other hand suffer a buildup. George Washington needed phlebotomies for that.

My Theory is that because of the high iron content in the male body, exposure to flouridated water is extemely hazardous to the male brain, blood-brain barrier, an area sensitive to radiation from celestial sources as well as bombs and cell phones.

NASA’s new priority is how to protect astronauts from going blind on the years-long trip to get wherever they are going.

“I absolutely agree that this is our number one priority,” Barratt said.

Why?

Because when Barratt blasted off to the international space station, he needed eyeglasses for distance. When he returned to Earth, his distance vision was fine, but he needed reading glasses. That was more than two years ago. And he’s not getting better.

“We really need to understand this. This is a critical point for understanding how humans adapt to spaceflight,” he said.

In the past few years, about half of the astronauts aboard the international space station have developed an increasing pressure inside their heads, an intracranial pressure that reshapes their optic nerve, causing a significant shift in the eyesight of male astronauts. Doctors call it papilledema.

Female space travelers have not been affected.

Some of the astronauts slowly recover. Others have not.

Space station astronauts typically spend about six months in orbit.

Barratt is one of 10 male astronauts, all older than 45, who have not recovered. Barratt returned from a six-month stint aboard the station in October 2009 and has experienced a profound change in his sight.

He used to be nearsighted. But now, the space veteran says he’s eagle-eyed at long distance but needs glasses for reading. There is no treatment and no answers as to why female space flyers are not affected.

For most essential vitamins and minerals, a male's body requires more. But that's not the case with iron. A female, depending on her stage of life, needs to take in up to more than double the amount of iron a man needs. During pregnancy, iron intake should almost triple a man's. The differences in our reproductive capabilities are cause for such a large difference.

Menstruation

Adult women need to increase iron intake once menstruation begins. Menstruation means a loss of blood every month, which can affect overall iron content of the body. Women must compensate by increasing iron intake. After the age of 50, or once menopause begins, women can reduce iron intake to the same as a man's.

IRON FLOURIDE FeF3·3H2O -- FeF2

en.wikipedia.org...(II)_fluoride

Chemical and physical properties

Iron(III) fluoride is a thermally robust, paramagnetic solid, consisting of high spin Fe(III) centers, which is consistent with the pale colors of all forms of this material. Both anhydrous iron(III) fluoride as well as its hydrates are hygroscopic.

[edit] Structure

The anhydrous form is adopts a simple structure with octahedral Fe(III)F6 centres interconnected by linear Fe-F-Fe linkages. In the language of crystallography, the crystals are classified as rhombohedral with an R-3c space group.[2] The structural motif is similar to that seen in ReO3. Although the solid is nonvolatile, it evaporates at high temperatures, the gas at 987 °C consists of FeF3, a planar molecule of D3h symmetry with three equal Fe-F bonds, each of length 176.3 pm.[3] At very high temperatures, it decomposes to give FeF2 and F2.[2]

Two crystalline forms - or more technically, polymorphs - of FeF3·3H2O are known, the α and β forms. These are prepared by evaporation of an HF solution containing Fe3+ at room temperature (α form) and above 50°C (β form). The space group of the β form is P4/m, and the α form maintains a P4/m space group with a J6 substructure. The solid α form is unstable and converts to the β form within days. The two forms are distinguished by their difference in quadrupole splitting from their Mössbauer spectra.[4]

[edit] Preparation, occurrence, reactions

Anhydrous iron(III) fluoride is prepared by treating virtually any anhydrous iron compound with fluorine. More practically and like most metal fluorides, it is prepared by treating the corresponding chloride with hydr
