Hazards of Depleted Uranium Contamination Training DU Video

Hazards of Depleted Uranium Contamination Training Video; Between October and December 1995, the U.S. Army's Depleted Uranium (DU) Project completed a series of training videos and manuals about depleted uranium munitions. This training regimen was developed as the result of recommendations made in the January 1993 General Accounting Office (GAO) report, Army Not Adequately Prepared to Deal with Depleted Uranium Contamination. The training materials were intended to instruct servicemen and women about the use and hazards of depleted uranium munitions. In addition, the training regimen included instructions for soldiers who repair and recover vehicles contaminated by depleted uranium. Metallic uranium (U) is a silver-white, lustrous, dense, weakly radioactive element. It is ubiquitous throughout the natural environment, and is found in varying but small amounts in rocks, soils, water, air, plants, animals and in all human beings. Natural uranium consists of a mixture of three radioactive isotopes which are identified by the mass numbers 238U (99.27% by mass), 235U (0.72%) and 234U (0.0054%). On average, approximately 90 µg (micrograms) of uranium exists in the human body from normal intakes of water, food and air. About 66% is found in the skeleton, 16% in the liver, 8% in the kidneys and 10% in other tissues. Uranium is used primarily in nuclear power plants. However, most reactors require uranium in which the 235U content is enriched from 0.72% to about 1.5-3%. Depleted uranium: The uranium remaining after removal of the enriched fraction contains about 99.8% 238U, 0.2% 235U and 0.001% 234U by mass; this is referred to as depleted uranium or DU. The main difference between DU and natural uranium is that the former contains at least three times less 235U than the latter. DU, consequently, is weakly radioactive and a radiation dose from it would be about 60% of that from purified natural uranium with the same mass. The behaviour of DU in the body is identical to that of natural uranium. Spent uranium fuel from nuclear reactors is sometimes reprocessed in plants for natural uranium enrichment. Some reactor-created radioisotopes can consequently contaminate the reprocessing equipment and the DU. Under these conditions another uranium isotope, 236U, may be present in the DU together with very small amounts of the transuranic elements plutonium, americium and neptunium and the fission product technetium-99. However, the additional radiation dose following intake of DU into the human body from these isotopes would be less than 1%. Applications of depleted uranium: Due to its high density, about twice that of lead, the main civilian uses of DU include counterweights in aircraft, radiation shields in medical radiation therapy machines and containers for the transport of radioactive materials. The military uses DU for defensive armour plate. DU is used in armour penetrating military ordnance because of its high density, and also because DU can ignite on impact if the temperature exceeds 600°C. Public Domain video.

Americans get screwed by their own governments and military lolz thats funny.

@49target

You'd have to breathe in a dose comparable to having a shell blow up next to you for it to be horribly dangerous. Seriously, its U-238. Alpha radation can't go through paper and we get it all day from the sun. It doesn't have enough energy to rip electrons off atoms, not exactly harrowing.

Your confusing this with the stockpiles of yellowcake saddam had, bought from the french, which leaked into the water table for about 10 years.

Ha, no wonder their kids all turn into monsters.. i still cant believe army officers told soldiers during 1991 said: "this Du round has less radiation than your house hold microwave." but what those soldier dont know is that those du rounds are solid U-238, which near them for 20min can reach the maximum radiation recieve by a normal person for a year. even worse during second gulf war, retarded usa decides to use nuclear waste from power stations. U-235 and 236 were found in returned soldier.

Cavities were simply redefined for those with high fluoride in their water... The cavities don't have rotten color to them though. The reality is that fluoride weakens bones and is neurotoxic.

IF it has topical benefits then OK.. But it doesn't belong in our water.

The same group that said fluoride in the water was good also said cigarettes and asbestos had no negative health effects.. This so called scientific investigation was in response to legal action against the aluminum industry.

@gregrutz So that's why nobody in America gets cavities? You are a dangerous moron.

Dental floridosis causes cavities.

[DRcaprice]

@myso2008 no we dont, we are just "misinformed". our government and millitary loves the people.

[gregrutz]

@wilsonpwt People who live in areas with natural Fluoride in the water don't get cavities. Hmmmm?

[gregrutz]

Sure fucked up a lot of Russian tanks, good work troops.
