Heavy water density.

well.

the second link was added for it`s info on the N and H bomb, as for the Tritium dangers, that was an irellevance really. but anyway, since it`s shifted towards that, these maybe of interest also:

 

http://www.ccnr.org/tritium_1.html

http://www.ccnr.org/tritium_2.html

 

as you said, it more the Oxides of it from the quick read I had.

The Canadian Coalition for Nuclear Responsibility (the source of your links) is a rabid anti-nuke group who seem primarily concerned that Canadian uranium and tritium has found it's way into U.S. weapons. They engage in the usual FUD of quoting numbers out of context, and quoting their officers as experts.

 

No one is suggesting that tritium is not a hazmat. However standards and practices that were in force over twenty-five years ago, have since been tightened. This same group is now protesting that tritium recovered form Ontario Hydro's reactors may wind-up in the hands of the U.S. military.

 

Tritium is used in luminous watches, self-powered signs and in the new BetaBattery technology. It's used as a tracer in a number of medical and industrial applications, and today sells for about $3000USD/oz. It's unlikely at those prices that anyone will be cavalier about releasing into the environment

Not to mention that if it's the pure gas, releasing it into the environment really can't happen. The gas is so freaking light that it just flies right out of the atmosphere, then converts into helium which is just as light and just as escapeable.

Yet nobody notices how the general public not only knows the plutonium and uranium isotopes needed to make nuclear weapons, but also the kilogram quantities and where to get it. Wow. I'd imagine a Dr. Strangelove situation soon.

Well that's not exactly particle physics there. It's simple science. ANYTHING that is based upon scientific findings will soon be known to everybody who wants to know. It's not like we can hide nature from people.

Found this on heavy water:

 

Partly because of its intrinsic structure (Katz, 1965), D2O increases the stability of organic molecules, macromolecules, viruses and vaccines. This can have important practical effects when vaccines and other heat-sensitive therapeutic substances must be distributed in developing countries, many of whose districts may lack electricity and refrigeration. A number of patents exist for biostabilizing ability of heavy water. These describe increased thermal and microbial stability and slower disaggregation of certain macromolecules (e.g., Crainic and Simpson, 1994). The presence of 95% D2O was found equivalent to a 4-5C reduction in storage temperature relative to H2O, for macromolecular pharmaceuticals such as vaccines; as little as 7-25% D2O helps prevent protein denaturation. D2O medium has been recommended for storing organs, tissues, tissue parts, proteins or enzymes, sera and blood preparations and for the perfusion of organs intended for transplants (Wenzel, 1974), microorganisms and enzymes (Hamaya and Horikoshi, 1989), and hydrolysable compositions such as alpha-hydroxy-carboxylic acids (especially benactyzine) (Teva Pharm. Ind. Ltd. 1989).

 

also:

 

Boron neutron capture therapy (BNCT) is used to treat tumors, especially brain tumors, by neutron irradiation of boron-containing compounds bound to malignant cells. Subsequent emission of -particle and other radioactive rays selectively kills these cells. The degree of neutron penetration into tissue, which limits this method, can be greatly increased if the patient's brain is "loaded" with heavy water (Hatanaka, 1989, 1991).

 

and:

 

In recent years patents have been obtained for the use of deuterated polymers and other compounds in laser and optical technology. These include deuterated 4-'nitrobenzylidene-3-halo -alkanoylamino-4-methoxy aniline crystals for nonlinear optical devices used for optical communication or information processing and optical recording material (Toray Ind. Inc. 1995), deuterated N, N'-diamino dicarboxylic acid amides with similar uses (Mitsui Petrochem. Ind. Co. Ltd., 1994), deuterated polyvinyl alcohols or polymethaerylic acids for optical recording devices (Iwamoto et al., 1992) and deuterated 1-arginine phosphate frequencyconversion crystals for use in lasers (Barker et al., 1992). Deuterated acrylate polymers have been claimed to be specially useful in optical fibres (Kitahara et al., 1984; Mitsubishi Rayon KK, 1984).

 

finaly:

 

Synthetic deuterated fibres may be incorporated in currency notes. This provides a method of tagging large amounts of currency (for example from drug smuggling) whose transfer is of dubious legality (Muller 1991)
