Uranium ExposureCytomg99 - 6 Answers
Holding a chunk of radioactive material on purpose in your hands can never be recommended. However, for the case of natural uranium, it is actually not that bad. Natural uranium is considered to be only weakly radioactive and it is unlikely that you will suffer from any immediate or long-term damages by holding it in your hands, although of course not recommended.
Since natural uranium is only weakly radioactive, it is actually used in a number of applications. Probably the most known ones are the use of depleted uranium. Depleted uranium refers to uranium that has had the fissile isotope uranium-235 (used in nuclear reactors) removed. The remaining uranium consists mostly of uranium-238 can be made into a metallic alloy of high density, i.e., 68% higher than lead. This is used in both the military and in civil technology.
In the military it is most commonly used in depleted uranium bullets and penetrators aiming to penetrate armors and other obstacles. Another commonly used area is depleted uranium tank armor where it is used to stop bullets and other projectiles. In civil technology we can find the use of uranium as ballast in aircrafts and radioactive shielding. The use of uranium as radioactive shielding tells us immediately that it cannot be very radioactive at all or else the exposure to the personnel would be worse than not having a shield at all.
Short term:Your hands begin to break down.Literally.Uranium emits alpha,beta and Gamma rays.The Alpha and Beta rays do the immediate damage,Although Alpha rays do not penetrate the skin,they do ionise the top layer of cells,literally breaking them down into their constituents,Beta rays are like lasers(beams of electrons)and when they bombard cells,they release free radicals and ions that are transported to the rest of the body and cause havoc!The water in the cells rapidly absorbs the energy as heat and starts rising in temperature.
LONG TERM:The Gamma rays penetrate into the deepest interior of your body,altering the dna of the cells they pass through.Then the cycles of cancerous cells forming all over your body start.
Uranium is the radioactive molecule. Radioactive molecules it has a property of giving out radiation including Alpha, Beta and Gamma radiations. this radiations are very dangerous as they have ionizing power property.Due to this property when held with bare hand my lead to change of genetic make up of the body as it my break hydrogen bond between two DNA strand which may lead to severe mutation and when this mutation becomes more prominent my subsequentily lead to death....
If you are speaking of uranium ore, the amount of radiation your hand would receive from a few seconds of exposure would barely be above "background radiation" found in the environment naturally during the course of a few days. If you have not experienced any skin damage after the exposure you probably did not receive enough to do damage. You should pay attention to any skin lesions, growths, eruptions, and see a dermatologist if they occur....
Uranium is radio active if you grab it without protection you will get cancer and die. All you have to do is see the report of what happened in chenobryl in ukraine, the nuclear reactors full of uranium exploded and the whole town was abandoned because of the radiation....
It basically enters the body disrupting cell growth and causes a whole lot of problems. Longer it is in your system then the more damage it can cause.
Dont play with Uranium!
