Re: FW: Heavy water face spray
The problem with Tritium it is its a beta emitter (electrons).
Sorry for the missed up. I know D2O it's not radioactive. I was talking about T2O and the activation of D2O produced in nuclear power plants (HWR) by neutron capture.
So you could not access a restricted zone if you have ingested D2O.
That's why I mean that product was just natural water.
About D2O water it is regulated. Because you can use it to produce a bomb with low % of U235.
Thanks for the note.

What dose are you talking about? It can't be radiation because D2O is non-radioactive (It is Tritium in THO or T2O forms that is radioactive "water").
The effects of tritium in the body have to do with the change in kinetics of reactions because the molecular weight of the hydrogen is doubled.

Considering the internal dose involved using D2O directly applied over the skin the Regulatory comission of UK should evaluate the ammount of D2O in this product (even though the elimination of water is fast in the human organism).
In case of beign approved (because the ammount of D2O is natural), it means we are talking about "ppm" of D2O, almost nothing.

Carlos Correa.

It should obviously be a really good product, but it doesn't say that
it's organic, too.

Hi.
Had an enquiry from the UK seller of the item on this website:
